Emerald

Beryl (Be3Al2(SiO3)6) with Chromium/Vanadium impurities

Garden Quartz (Lodalite)

Silicon Dioxide with various mineral inclusions (SiO2)

Milky quartz

Quartz (silicon dioxide, SiO₂)

Red gemstone ring, likely ruby or synthetic ruby

Corundum (Al₂O₃), chromium-colored; the image alone cannot confirm whether it is natural or synthetic

Blue-green tumbled gemstone, likely turquoise or dyed turquoise

Turquoise: hydrated copper–aluminum phosphate, CuAl₆(PO₄)₄(OH)₈·4H₂O; identification is uncertain from the blurry image

Blue Sapphire

Corundum (Al2O3 with trace Titanium and Iron)

Quartz (Smoky Quartz variant)

Silicon Dioxide (SiO2)

Raw ruby (corundum)

Ruby variety of corundum, aluminum oxide (Al₂O₃), colored chiefly by chromium

Turquoise cabochon or turquoise-bearing material

Turquoise, hydrated copper aluminum phosphate — CuAl₆(PO₄)₄(OH)₈·4H₂O

Strawberry Quartz

Silicon Dioxide with Hematite inclusions (SiO2 + Fe2O3)

Colorless faceted gemstone, likely cubic zirconia

Cubic zirconia (synthetic ZrO₂), possibly glass or white sapphire

Ruby (varieties of Corundum)

Aluminum oxide (Al2O3) with Chromium traces

Red faceted gemstone, likely synthetic ruby

Corundum (Al₂O₃); ruby is red chromium-bearing corundum

Polished pink quartz cabochon

Quartz (SiO₂), likely rose quartz or included quartz

Amethyst (faceted gemstone)

Quartz, silicon dioxide (SiO₂), purple variety colored mainly by iron-related defects

Colorless faceted gemstone, likely cubic zirconia

Polished blue-black cabochon, likely blue obsidian or dyed glass-like stone

Indeterminate from image; possible natural obsidian (volcanic glass), commonly SiO₂-rich rhyolitic glass

Colorless faceted gemstone, likely cubic zirconia or diamond

Uncertain from image; cubic zirconia (ZrO₂) is a common diamond simulant, while diamond is crystalline carbon (C)

Colorless faceted gemstone (likely cubic zirconia)

Cubic zirconia, zirconium dioxide (ZrO₂); possibly synthetic quartz or glass imitation

Faceted golden beryl (likely heliodor)

Beryl, Be₃Al₂Si₆O₁₈; yellow color from iron impurities

Hematite cameo or hematine imitation

Hematite (Fe₂O₃); possibly synthetic hematine or black glass

Clear faceted gemstone, likely quartz (rock crystal)

Quartz, silicon dioxide (SiO₂); visual identification is uncertain because the stone is heavily faceted and photographed with flash

Green cabochon gemstone, likely glass-filled or synthetic emerald imitation

Uncertain; possible synthetic emerald (beryl, Be₃Al₂Si₆O₁₈) or green glass
