Lab-grown gemstones that do not exist in nature are primarily man-made compounds designed for industrial or jewelry use, often referred to as synthetic, simulated, or proprietary stones. Key examples include Cubic Zirconia (CZ), Yttrium Aluminum Garnet (YAG), Gadolinium Gallium Garnet (GGG), and many synthetic colored gems.
Common Lab-Only Gemstones
Cubic Zirconia (CZ): While zirconia is found in nature as tiny monoclinic crystals, the stable cubic form is rarely found and is instead almost exclusively produced in labs as a durable, inexpensive diamond substitute.
YAG (Yttrium Aluminum Garnet): A synthetic material widely used for its hardness and high refractive index, originally developed for laser applications rather than jewelry.
LuAG (Lutetium Aluminum Garnet): Another synthetic garnet not found in nature.
Moissanite: While natural moissanite (silicon carbide) exists, it is extremely rare; therefore, virtually all gem-quality moissanite in jewelry is lab-grown.
Synthetic Spinel: Frequently manufactured in colors not found in natural spinel, often used to mimic other stones like emerald and blue sapphire.
Differences in Lab vs. Natural
Composition: These materials are often not just grown, but manufactured using compounds not commonly found in the Earth's crust in a crystalline state.
Appearance: These stones often exhibit an "incredibly bright, saturated, and uniform color" or "flawless" appearance that is exceptionally rare to find in natural gems, which typically exhibit inclusions.
Properties: Some lab-grown materials, such as those and listed on Reddit, are not true silicates (like natural garnets) but rather aluminates or gallates.

Nephrite Jade Origins from Around the World | Where does jade come from?
The USA has significant deposits of nephrite jade, particularly in Wyoming, Alaska, California, and Washington. Wyoming is renowned for high-quality nephrite, including olive green and rare "turtle back" varieties. California's Jade Cove in Big Sur is famous for underwater jade deposits, while Alaska features the Jade Mountains.
Key Locations and Types
Wyoming: Known for olive green and black nephrite, often found with quartz inclusions, making it popular for jewelry and carving.
California: The Central Coast, specifically Jade Cove in Big Sur, is a noted source for collectors.
Alaska: The Jade Mountains in Kobuk Valley National Park are a historic source of, particularly, nephrite jade.
Washington: Various deposits exist, contributing to the diversity of American jade.
Italian Jade Cabochon
European jade, primarily found as rare green jadeite in the Italian Alps, was prized during the Neolithic period (c. 5300 BC) for producing high-quality polished axeheads and rings, symbolizing wealth and power.
