Magnetic properties in gemstones range from strong, natural magnetism to subtle responses detectable only with specialized tools. While Magnetite (or Lodestone) is the most powerful naturally magnetic mineral, many other gems like Garnets and Tourmalines exhibit "paramagnetism" due to traces of iron or manganese in their chemical makeup.
Core Magnetic Gemstones & Minerals
Magnetite (Lodestone): The strongest naturally occurring magnetic mineral. Lodestone is a specific variety of magnetite that acts as a permanent magnet, capable of attracting iron objects like paperclips.
Magnetic Hematite: While natural hematite is typically not magnetic, a common synthetic version known as Hematine is manufactured to be strongly magnetic for use in therapeutic jewelry.
Pyrrhotite: A sulfurous iron mineral that is naturally and often strongly magnetic, though typically less intense than magnetite.
Iron-Bearing Gems: Many popular gemstones show weak magnetic attraction (paramagnetism) because they contain iron. These include:
Garnets: Specifically
Almandine
Spessartine
Pyrope varieties.
Peridot: Always contains iron, making it one of the most magnetic transparent gems.
Tourmaline: Varieties like Indicolite (blue)
Schorl (black) often show a magnetic response.
Magnetic gemstones are primarily iron-rich minerals that either naturally attract magnets or can be magnetized. Magnetite (often called Lodestone in its naturally magnetized form) is the most magnetic natural mineral on Earth.
Rhodonite
Black Star Diopside also exhibit magnetic properties due to high iron or manganese content.
The term Marco Polo Pearl most likely refers to the Arco-Valley Pearl, a massive 575-carat natural pearl famously gifted to Marco Polo by Kublai Khan.
Alternatively, it may refer to recent commemorative collectibles or specific local businesses.
1. The Arco-Valley Natural Pearl
This historic gemstone is one of the largest natural pearls in the world.
Origin: It belonged to the Mongol ruler Kublai Khan, who gave it to Marco Polo as a parting gift in the 13th century.
Description: It is a baroque (irregularly shaped) pearl weighing 115 grams(575 carats) with distinct blue-pink overtones.
History: The Polos allegedly smuggled this and other gems back to Venice hidden in their clothing to prove their wealth and travels.
In his travels, Marco Polo documented the pearl industry in Maabar(India), describing how kings wore necklaces of over 100 pearls to represent their daily prayers.
Arco-Valley Pearl
The Arco-Valley pearl, is a 575-carats natural blister baroque pearl. Historical accounts suggest that the remarkable pearl, thought to have been in the possession of Kublai Khan, the 13th century emperor of China and grandson of Genghis Khan, may have been bestowed upon Marco Polo as a generous gift. In May 2007, the pearl was put up for auction with an estimated value of up to $8 million dollars. The Arco Valley Pearl has been unseen for many years.
The second largest natural pearl ever discovered, the Arco Valley Pearl is reported to have once been owned by the famed explorer Marco Polo, who was given it by the Mongolian emperor Khubilai Khan. It's the largest natural pearl outside of a museum in the world today.
Pearls are unique, organic gemstones created by living mollusks (oysters and mussels) rather than being mined from the earth. They are primarily composed of nacre, forming layers around an irritant. Valued for their luster and rarity, pearls require gentle care (3.5–4 on the Mohs scale) and are distinct from mineral gems
Key Characteristics and Types of Pearls
Formation: Pearls form inside saltwater or freshwater mollusks when layers of nacre coat an irritant, such as a parasite or piece of shell.
Organic Origin: Unlike diamonds or rubies, pearls are not minerals, making them unique in the gem world.
Types: Major types include saltwater pearls (Akoya, Tahitian, South Sea) and freshwater pearls.
Colors: While white and cream are classic, pearls occur in a wide variety of colors, including black, grey, pink, green, and blue, often influenced by the mollusk type.
Quality Factors: The GIA defines 7 value factors for pearls: size, shape, color, luster, surface quality, nacre quality, and matching.
GIA +5
Pearls vs. Mineral Gemstones
Durability: Pearls are soft and delicate (3.5–4 on the Mohs scale), making them susceptible to damage from chemicals, perfumes, and dry air.
Maintenance: Pearls should be stored separately, ideally in soft cloth, to avoid scratches from harder, mineral-based gemstones.
Symbolism: They are renowned as symbols of purity and wisdom.
Combining Pearls with Gemstones
Pairings: Pearls are often paired with vibrant stones such as blue sapphires, amethyst, citrine, peridot, and rose quartz to complement their luster.
Jewelry Use: They are commonly used in necklaces, earrings, and rings, frequently combined with materials like gold vermeil or in combination with mother-of-pearl.
Occasions: Pearls are traditional gifts for the 3rd and 30th wedding anniversaries.
Price Worth Value
South Sea pearls, particularly large, perfectly round, or deep gold varieties, are the most expensive cultured pearls, with necklaces often exceeding $200,000 due to their rarity, 5-year cultivation time, and large size.
Top Factors Driving High Pearl Prices
Type & Rarity:South Sea pearls are most expensive ($1,000–$100,000+), followed by Tahitian ($500–$25,000+) and high-end Akoya ($300–$10,000+).
Size: Pearls larger than 15.0mm are rare and exponentially more expensive.
Shape: Perfectly round pearls are the most valuable due to difficulty in cultivation.
Color: Deep gold South Sea and deep peacock Tahitian pearls are highly prized.
Nacre Quality: Thick, high-luster nacre, especially in saltwater, increases
Varieties
South Sea pearls are large, rare, and highly valuable pearls cultured from Pinctada maxima oysters, primarily in Australia, Indonesia, and the Philippines. Renowned for their satin luster and sizes typically ranging from 9–20mm, they come in white, silver, and golden colors. They are considered among the most valuable cultured pearls.
Key Characteristics and Types
Varieties: White South Sea pearls are predominantly produced in Australia, while Golden South Sea pearls are associated with the Philippines and Indonesia.
Luster: Known for a "deep, molten radiance" or satin glow rather than a sharp sparkle.
Shapes: They appear in perfectly round, drop, and baroque (irregular) shapes.
Size: Generally larger than other pearls.
treasured for their large size and soft, satin-like white, cream, or golden colors
Tahitian black pearls are cultured saltwater pearls from the black-lipped oyster (Pinctada margaritifera), primarily cultivated in French Polynesia. Ranging from 9–12mm, they feature natural dark, iridescent colors like green, blue, and peacock.
Key Aspects of Tahitian Black Pearls
Colors and Overtones: While called "black," they display a range of colors including dark green, blue, bronze, purple (aubergine), and silver. The most prized is a greenish-black known as "peacock".
Tahitian pearls are cultivated in the warm, clean waters of the South Pacific.
The first successful, high-quality round Tahitian pearls were produced in the early 1970s, establishing a strong, lasting, and popular industry
Melo Melo and Conch pearls are exceptionally rare, non-nacreous natural gems with porcelain-like luster and distinct flame-like patterns, prized for their unique colors rather than typical pearl iridescence. Melo pearls, found in Southeast Asian sea snails, display vibrant orange to brown hues, while Conch pearls are renowned for their rare, delicate pink coloring.
Melo Melo Pearls
Origin: Produced by the Melo melo sea snail (a carnivorous gastropod) in the South China Sea, particularly near Vietnam, Myanmar, and Thailand.
Characteristics: These are non-nacreous, meaning they lack the typical pearly layers of traditional pearls. They have a "porcelaneous" luster—a glazed, glossy surface that often exhibits a unique flame-like pattern.
Color & Shape: Ranging from light orange to deep tangerine (the most prized) to brown, they are often large and remarkably round.
Rarity: They cannot be cultured; they are natural treasures formed over decades, making them highly coveted by collectors and historically favored by Vietnamese royalty.
Conch Pearls
Origin: Formed inside the Queen Conch (Strombus gigas), a sea snail found primarily in the Caribbean.
Characteristics: Also non-nacreous with a similar porcelain-like surface, they are often characterized by a delicate, silky, flame-like structure.
Color: Known for their distinct, vibrant pink, though they can range from yellow to brown.
Rarity: Exceptionally rare, as they are natural and cannot be cultured, often found by chance during fishing.
World Record
Pearl of Puerto (34 kg / 75 lbs): Discovered by a Filipino fisherman in 2006 near Palawan Island. He kept it under his bed for 10 years as a lucky charm before bringing it to local officials in 2016 after a house fire. It is currently displayed at the Puerto Princesa City Hall and is valued at approximately $100 million.
The Giga Pearl is widely recognized as the world's largest natural pearl, weighing 27.65 kilograms (over 60 lbs) and measuring 15.5 x 9 x 8.25 inches. Certified by the Gemological Institute of America (GIA), this cream-colored, misshapen specimen was found in the Philippines and is valued at over $140 million.
No, the Giga Pearl is not considered a South Sea Pearl. It is a massive, natural pearl formed by a Tridacna gigas(giant clam), whereas South Sea pearls are cultured in Pinctada maxima oysters. While discovered in the Philippines (a South Sea region), its origin as a clam pearl makes it biologically and physically distinct from oyster-grown South Sea pearls.
Marco Polo,a 13th-century Venetian merchant, provided some of the Western world's earliest and most vivid accounts of the vast gemstone wealth in Asia. His family were gem merchants, and his writings often focused on the quality, mining, and trade of precious stones he encountered during his 24-year journey.
Famous Gemstones and Origins
Polo's accounts highlighted several regions as the primary sources for the world's most valuable gems:
Rubies and Spinels (Badakhshan): In the province of Badakhshan (modern-day Afghanistan and Tajikistan), Polo described mines producing "Balas Rubies". Modern mineralogy identifies these as high-quality red spinels, which were often mistaken for rubies in the medieval world.
Pearls (Ceylon and India): He described Ceylon (Sri Lanka) as the "Island of Gems," reporting that precious stones were so abundant they could be found on riverbanks. In the Gulf of Mannar, he documented sophisticated pearl fishing operations where divers collected oysters from the seabed.
Diamonds (India): Polo recorded a famous, albeit fantastical, account of diamond "harvesting" in the kingdom of Mutfili (near modern Golconda). He claimed locals threw raw meat into deep, snake-infested ravines for diamonds to stick to; eagles would then swoop down to retrieve the meat, and hunters would later collect the gems from the eagles' nests or droppings.
Lapis Lazuli: He noted that the finest lapis lazuli in the world came from the steep mountains of the Hindu Kush in Badakhshan.
The Great Khan’s Treasure
During his service to Kublai Khan, Polo witnessed immense concentrations of wealth:
The Mint: He was fascinated by the Khan's use of paper money, noting that all gold, silver, and gems brought into the empire had to be exchanged at the Mint for this currency, effectively concentrating the empire's physical treasure in the Khan's possession.
The Arco-Valley Pearl: Legend and some historical accounts suggest Kublai Khan gave Marco Polo a massive, 575-carat baroque pearl (the Arco-Valley Pearl) as a parting gift.
The "Hidden" Treasures
Upon returning to Venice in 1295, the Polos were reportedly unrecognized until they ripped open the seams of their shabby traveling clothes to reveal a cascading fortune of rubies, sapphires, diamonds, and emeralds they had sewn into the linings for safety during their journey.
Marco Polo (1254–1324) was a Venetian merchant and explorer who documented vast, exotic gemstone wealth during his travels to Asia. He reported on massive diamonds in India’s Golconda region and enormous rubies and sapphires in Ceylon (Sri Lanka). Polo was famously gifted the 575-carat Arco Valley Pearl by Kublai Khan.
Key insights on Marco Polo's connection to gems include:
Ceylon (Sri Lanka): Polo identified this region as the world's premier source for high-quality, large rubies, sapphires, and other gems, describing them as abundant.
Golconda Diamonds: He provided early, partially legendary accounts of the diamond mines in India, noting the exclusive access rulers had to the largest stones.
The Arco Valley Pearl: A 575-carat natural baroque pearl, gifted by Kublai Khan, is believed to be one of the treasures Polo brought back, often considered the largest private natural pearl.
Gem Smuggling: To safely return to Italy, the Polo family reportedly concealed their treasure, including precious stones, within their clothes.
Legacy: Modern high-end jewelry collections, such as those by Alessio Boschi, are inspired by his travels, often combining materials like Burmese jade with historical motifs from his 13th-century journey.
He was also one of the first Westerners to report that rubies were perceived as having special, phosphorescent powers.
Here’s what you’ll learn when you read this story:
The Nuestra Señora de las Maravillas left Spain heavily loaded with royal treasure and salvaged riches, but after a collision in the Bahamas, it sank within 30 minutes—scattering gold, silver, and artifacts across an eight-mile debris field.
Despite decades of looting and recovery efforts that pulled up millions of coins and silver bars, large portions of the wreck—including contraband goods and personal artifacts—remained buried under sand and coral.
After securing excavation rights in 2020, Allen Exploration uncovered gold chains, emerald pendants, and rare historical items.
Carrying a double load of bounty, the Nuestra Senora de las Maravillas (“Our Lady of Wonders”) wrecked about 43 miles off the shore of the Bahamas in 1656. During its descent, the ship scattered a debris trail at least eight miles long. Scavengers pillaged that bounty for centuries until the government put a moratorium on it in the late 1990s.
But the water still hid a surprising amount of treasure. Under a new excavation license granted in 2020, Allen Exploration, an investment company that partnered with the Bahamian government, finally found it.
At least 3.5 million pieces of eight (a global currency from Spain) and silver bars had already been salvaged from the Maravillas. This latest search, led by the retired millionaire plastics businessman Carl Allen, combed the ocean floor to locate more artifacts. He ended up finding gold chains, emerald pendants, and plenty of 1600s-era remnants worthy of a museum.
“When we brought up the oval emerald and gold pendant, my breath caught in my throat,” Allen said in a news release. “I feel a greater connection with everyday finds than coins and jewels, but these Santiago finds bridge both worlds. The pendant mesmerizes me when I hold it and think about its history. How these tiny pendants survived in these harsh waters, and how we managed to find them, is the miracle of the Maravillas.”
I found a hidden treasure trove in the Caribbean!
When it left Spain for Colombia in 1654, the two-deck Spanish galleon Nuestra Senora de las Maravillas was armed with 36 bronze cannons. Her purpose was to bring back treasure to Seville, both as royal tax and private property.
The weather forced the crew to pause for the winter in Colombia. Coincidentally, when the Jesus Maria de la Limpia Concepcion sank off Ecuador, salvage of the wealth from that wreck was transferred to the Maravillas.
So, when the Maravillas set sail for Spain, after a stop in Havana, it was doubly loaded with valuables.
That fortune didn’t make it far. Just after midnight on January 4, 1656, while the ship was navigating the Bahama Channel, slicing between Florida and the Bahamas, the Nuestra Senora de la Concepcion, lead ship in the Tierra Firme fleet, struck the Maravillas. Within 30 minutes, the ship sank, and only 45 of the 650 crew, merchants, and travelers on board survived.
The trail of treasure spread as much as eight miles and had been buried beneath sand and dead coral on the Little Bahama Bank ever since. Under the Antiquities, Monuments, and Museum Act, all wreckage in the Bahamian water is the property of the Government of the Bahamas. Allen Exploration (AllenX) earned a survey license in 2019 and an excavation license in 2020.
“The Maravillas offers an opportunity to study the end of the Golden Age of Spain that drew to a close with the Treaty of the Pyrenees in 1659 after the Franco-Spanish War,” according to the Bahamas Maritime Museum. “The wreck of the Maravillas is a sunken porthole into the consumer tastes of Spain in a very tight and crucial period in the country’s history and into its colonial relationship with Mexico, Colombia, Peru, and Bolivia in the Americas.”
Experts figured there wasn’t much left to find from the shipwreck, but Allen Exploration believed the stern castle had broken off and drifted away, opening a new area of exploration in an area 7.5 miles by 5 miles. Using magnetometers and Icon A5 aircraft, the team started an original search with the humble goal of investigating the personal belongings of officers, crew, and passengers to reconstruct daily life at sea.
They found far more than that.
Throughout the haul, they discovered valuable pieces, including a two-pound, six-foot-long gold filigree chain with ornate decorations, uncut emeralds and amethysts, and jewel-encrusted pendants. Some of the pieces, such as a golden pendant in the form of a scallop shell, are tied to the Order of Santiago, a Christian order of knights founded in about 1160 in Spain to fight Spanish Muslims and protect pilgrims. Plenty of valuables weren’t on the original ship’s cargo manifest, highlighting a common practice of the day: smuggling.
Ten Spanish salvage expeditions have recovered “a huge chunk of the Maravillas’ treasure cargo,” Allen says. “The galleon, though, was stuffed with contraband illegally greasing the palms of Spanish merchants and officials. Defrauding the Spanish Crown continued into the salvage years. Our archaeology is finding that most recovered coins were minted in Mexico. But the Maravillas didn’t officially load coins in Mexico. Illegal contraband again raises its suspicious head.”
The team also found iron fasteners from the hull; rings and pins from the rigging; olive jars; plates; a silver sword hilt; and other personal belongings once part of the 891-ton Maravillas. Each item is being mapped in geo-referenced databases.
More than enjoying the excitement of the historical finds, AllenX wants to learn from the process. “By mapping each type of find, AllenX is finally reconstructing the mystery of how the ship was wrecked and fell apart,” James Sinclair, a marine archaeologist with the project, says in the news release. “This isn’t just forensic marine archaeology. We’re also digging into former excavations, working out what previous salvage teams got up to, where and why. So much data has been sadly lost from this ravaged wreck.”
Sinclair says the company is continuing the hunt for more treasure and trying to paint a more detailed picture of how the ship was destroyed. “Now we’re connecting the dots, for the first time plotting how the Maravillas galleon broke up in 1656 and became a scattered wreck.”
From August to December 1654, the Spanish galleonNuestra Señora de las Maravillas(Our Lady of Wonders) waited in Cartagena, Colombia, for a cargo of silver that would never arrive. Unbeknownst to the ship’s crew,its supply vessel, theJesus Maria de la Limpia Concepción, had sunk on a reef off Ecuador that October.
Only after theConcepción’s silver was salvaged and stowed on theMaravillas, alongside the galleon’s own fresh load of silver coins and bars, did theLady of Wondersembark on its journey home to Spain. At the time, ships sailing between Europe and the Americas had to pass through theBahama Channel, a shortcut between Florida and the Bahamas’ then-unmapped reefs. There, on January 4, 1656, the galleon lost its bearings.
Sailing as the vice-flagship of theTierra Firme(Mainland) fleet, theMaravillaswas rammed by its flagship and violently collided with a reef. The vessel sank like a stone, weighed down by its double cargo—the wreck of a wreck.
Today, the 891-tonMaravillasis the sunken crown jewel of the Bahamas, an island nation abounding in shipwrecks. Long exploited bytreasure hunters, the 17th-century galleon is now being surveyed scientifically for the first time—an endeavor showcased in theBahamas Maritime Museum, a privately owned institution slated to open in Freeport, Grand Bahama, on August 8.
“TheMaravillashas never seen the right level of archaeological respect,” saysDavid Gibbins, a marine archaeologist and bestselling novelist who is not involved in the ongoing excavations. “Past teams indiscriminately used smash-and-grab tactics. Everyone thought the ship, the wreck, was destroyed forever.”
Exploring theMaravillas
Over 40 miles off the Little Bahama Bank, agroup of scientistsheaded by philanthropist and explorerCarl Allentowsmagnetometers(navigational devices that measure magnetic fields) across miles of seabed. Every find is plotted, from a shard of pottery to a cannon; currents are modeled, and seabed geology is assessed. Up in the air, an Icon A5 aircraft searches for scattered wreckage. Beneath the waves, a Triton submarine plummets down to 650 feet, eyes peeled for sections of theMaravillasthat may have slipped into the abyss. Even with all hands on deck, the work is slow and painstaking.
Throughout history, the waters surrounding the Bahamas have been aninfamous playgroundfortreasure hunters. Founded by Allen in 2016,Allen Exploration(also known as AllenX) is the first team to study theMaravillaswith scientific rigor. Allen, a multimillionaire who made his money through a plastics business, also owns afleet of yachtsand the Bahamian island ofWalker’s Cay.
In 2019, the Bahamian government granted AllenX a license to explore the wreck, ending amoratoriumon shipwreck salvage expeditions that had been in place since 1999. The company owns and operates the soon-to-open museum, which features finds from theMaravillas, as well as displays on local history and culture.
TheMaravillaswas built in the province of Guipúzcoa, today part of the Basque Autonomous Community in northern Spain, during the 1640s. It was named after a 13th-centurysculpture of the Virgin Marythat was housed in a Carmelite convent in Madrid and famed for its miracles. The ship featured two decks, a chapel for mass and a golden lion figurehead. Stowed in its cargo hold were royal and private consignments and smuggled treasures.
Some 650 people—a mix of travelers, merchants and crew—were on board theMaravillasduring its final voyage. After the ship was wrecked, enormous waves broke it into pieces. Most of the passengers grabbed hold of floating debris and drifted away, never to be seen again. About 150 clung to pieces of the hull still above the water, only to die from exposure or be eaten by sharks. By sunrise on January 5, only 45 remained alive.
Previously, many scholars believed theMaravillashad been salvaged into oblivion. The Spanish Empire had no intention of leaving a royal ransom sitting on the ocean floor. Between 1656 and 1679, Spain sent ten expeditions to salvage the wreck site. English, French, Dutch and Bahamian ships tried their luck with the wreck in the late 17th and 18th centuries.Moderntreasure huntershit the site hard between the 1970s and early 1990s. Over three centuries, around 3.5 millionpieces of eightand an undisclosed but significant number of silver bars were salvaged.
Without accurate records for both the historic and modern salvages, exactly what was lifted and what was left behind is educated guesswork. AllenX’s experts discovered that some Spanish treasure hunters went to great lengths to conceal their sunken bonanza. One Captain Iriarte hid gold from his 1657 salvage and was sentenced to death by hanging. In 1661, the Spanish crown sued Juan Somovilla de Tejada and Gaspar de los Reyes Palacio for failing to declare one millionpesos recovered from the wreck. Over the centuries, countless happy-go-lucky divers stuffed their breeches with coins from the site.
“AllenX reversing the past’s disrespectful quarrying of the wreck comes as a relief,” says Gibbins. “Finally, we can look forward with hope to some science answering research questions long thought dead and buried.”
To search for surviving traces of the wreck, AllenX used magnetometers, which identified 8,800 metallic hits (spots of potential interest) across a search area covering 11 by 5 miles. Clusters of cultural debris soon emerged: shards of Spanish olive jars and Chinese porcelain, iron straps used to rig cannons on gun decks, glass wine bottles, sword handles, silver coins, tobacco pipes, and jewelry. Together, the finds serve as a sunken porthole into the tail end of theGolden Age of Spain, a flourishing of art and exploration that spanned roughly 1500 to 1681.
According toJames Sinclair, director of marine archaeology for the AllenXMaravillasproject, the researchers are delving into the mystery of the ship’s demise by thoroughly mapping all of their finds. “This isn’t just forensic marine archaeology,” he says. “We’re also digging into former excavations, working out what previous salvage teams got up to, where and why. So much data has been lost from this ravaged wreck. It’s time to reverse those trends.”
The wreck’s rare treasures
Held annually since 1566, the Tierra Firme’s yearly sojourns to the New World had one main goal: to fill the fleet’s ships with riches from Latin America’sgold, silver and emerald mines, as well as copper, tobacco and Venezuelan pearls. Mined first by Indigenous peoples and then by enslaved Africans, these precious metals and gems helped fund theFranco-Spanish War, which began in 1635 and ended in 1659.
Though gold and silver “were a large part” of theMaravillas’ voyage, Allen says he feels a “greater connection with everyday finds than mass-produced coins. We’ve discovered artifacts that connect with the crew and passengers. … Everything you touch, from a musketball to a piece of jewelry, links with the past to people like you and me.”
A remarkable find made by the AllenX team is an almost 2-pound, 6-foot-long gold filigree chain crafted from circular flat and tubular links and decorated with rosettes. A similar chain appears in aportraitofPhilip IVof Spain, who was on the throne when theMaravillassank. The jewelry’s ornate appearance hints that it was commissioned by an elite client—perhaps even a royal one.
During the 17th century, merchants sometimes used individual gold chain links as currency. “This, however, cannot be said of theMaravillas’ chains,” notesBeatriz Chadour-Sampson, a jewelry historian and curator who has examined photos of the finds. “These are of high-quality craftsmanship, almost certainly made in Spanish Manila in the Philippines, possibly by Chinese craftsmen.”
Chadour-Sampson adds, “Such chains are a rare survival, as almost all were later melted down to be refashioned.”
The star finds from AllenX’s three years of underwater surveys are tiny jewels, no more than two inches long, found on top of dead coral reefs. “Exploring the debris field veering away from theMaravillas’ strike point”—where the boat was wrecked—“is a mixed feeling,” says Allen. “The sea bottom is barren. Thecolorful coralthat divers remembered from the 1970s is gone, poisoned by ocean acidification and choked by shifting sand. It’s painfully sad. Still lying on those dead grey reefs, ... here and there, are sparkling finds.”
Uncut emeralds and amethysts, neither of which are listed on theMaravillas’ Spain-bound cargo, are especially common. Spanish galleons returning from the Americas oftencarried contrabandat least 20 percent above what was declared, and sometimes as much as200 percent over.Smugglingwas a national sport.
“[This] galleon was stuffed with contraband illegally greasing the palms of Spanish merchants and officials,” Allen says. “Our [surveys are] finding that most recovered coins were minted in Mexico. But theMaravillasdidn’t officially load coins in Mexico.”
In addition to smuggled loot, the ship carried personal items and rare objects ready to be sold to wealthy Europeans. Among these privately owned treasures was a golden pendant shaped like a scallop shell and adorned with the cross of Santiago, or Saint James. The pendant is backed with an Indianbezoar stone, famous in Europe for its healing properties. At the center of a second golden pendant, this one oval in shape, is a gold cross of Saint James atop a large Colombian emerald. The outer edge is framed by 12 square emeralds, perhaps symbolizing the 12 apostles.
AllenX has so far tied four finds—including three pendants—to theOrder of Santiago, Spain and Portugal’s most prestigious military body. They were likely owned by high-ranking officers on theMaravillas, as the order’s knights were especially active in the sea trade. When Portuguese navigatorVasco da Gama, the first European to sail to India, commanded a 21-ship armada in 1502 and 1503, it sailed with eight Santiago knights. Martin de Urnieta, the shipwright who finished building theMaravillasin 1647, was also a knight of the order.
The jewelry’s scalloped shape was designed to replicate the scallops picked up along the coast of Galicia, in northwest Spain, and carried home by pilgrims who visited the shrine ofSantiago de Compostela. Built by Spain’s Alfonso III in 899 C.E., the pilgrimage destination supposedly housed Saint James’ bones. During the medieval era and beyond, knights of the Order of Santiago were charged with protecting the 500-mile pilgrimage route from attack by the Moors.
“Finding so many pendants linked to the Order of Santiago in varying designs and gemstones is incredibly rare on land,” says Chadour-Sampson. “They would have been strung around the neck on gold chains to show that pious owners had made a pilgrimage to Saint James’ shrine. … They make the decks of theMaravillasfeel like a floating aristocratic court mixed with the sweat of sailors heaving on rigging.”
Artifacts recovered from theMaravillasby AllenX form the bulk of the Bahamas Maritime Museum’s collection. Carl and his wife,Gigi Allen, have also donated materials salvaged by other teams in Bahamian waters between the 1970s and 1990s and acquired for the museum.
Next to the shipwrecked wonders are displays on a range of topics, including the IndigenousLucayanpeoples, theBahamas’ little-known rolein the transatlantic slave trade, and the island of New Providence’sinfamous rolein the golden age of piracy. The museum worked closely with the Bahamian government to plan these exhibits.
“For a nation built from the ocean, it’s astonishing how little is understood about the Bahamas’ maritime links,” says Michael Pateman, the museum’s director. “Few know that the … Lucayan peoples, for instance, settled here 1,300 years ago. Or that the whole population, up to 50,000 people, was forced out by Spanish guns, made to dive forpearls off Venezuelaand killed off in less than three decades.”
Pateman adds, “There was a dazzling Old World culture in the Bahamas long before European ships thought they found a New World.”
Under theAntiquities, Monuments and Museum Act(amended in 2011), all wreckage in Bahamian waters is the property of the Bahamian government. AllenX is keeping all of itsMaravillasfinds together, conserved for display or storage in the museum. None of the artifacts recovered will be sold.
The museum’s goal is to share the Bahamas’ maritime legacy with Bahamians and the wider world. Visitors can watch artifacts from the wreck of the Maravillasbeing conserved through a glass window in an on-site lab; a museum education program teaches children about traditional boat building and archaeological techniques.
Since 2019, AllenX has discovered a total of 18 wrecks in the Bahamas. The company’s archaeologists are still searching for theMaravillas’sterncastle(a raised section of the ship), which probably broke off and drifted away before the galleon sank, and they plan to continue their work long after the museum opens its doors.
“I could spend my life looking for ships in the Bahamas and only scratch the surface of what’s down there,” says Allen. “There are wrecks here from the 1500s forward. And who knows what’s even earlier? These potential discoveries can help shape the story of the making of the Americas and the peoples that owned the land before colonial Europe arrived.”
