Synthetic Glass (Often Categorized As A Simulated Mineral)

Strawberry Quartz (Hematoid Quartz)

Silicon Dioxide with Iron Oxide inclusions (SiO2 + Fe2O3)

Chipped Glass/Plastic Fragment

Silicon dioxide (SiO2) for glass (amorphous) or various polymer compounds for plastic

Red gemstone ring, likely synthetic ruby or red glass

Unidentified red faceted stone; ruby is corundum (Al₂O₃)

Red cabochon gemstone ring (likely ruby or red spinel; identity unconfirmed)

Possibly corundum (ruby, Al₂O₃) or spinel (MgAl₂O₄); visual identification alone cannot distinguish these from glass or synthetic stones.

Smoky Quartz

Silicon Dioxide (SiO2) with aluminum impurities and natural radiation

Cubic Zirconia (simulant) or Diamond

ZrO2 (Cubic Zirconia) or C (Diamond)

Hematite

Iron(III) oxide, Fe2O3

Ruby / Red Corundum

Al2O3 (Aluminum Oxide with Chromium trace)

Red corundum (ruby) crystal fragment

Corundum, Al₂O₃; ruby is red corundum colored mainly by chromium

Emerald in Matrix

Beryl (Be3Al2Si6O18) with Chromium/Vanadium impurities

Tourmalinated Quartz

Crystalline Silicon Dioxide with Schorl inclusions (SiO2 + NaFe3Al6(BO3)3Si6O18(OH)4)

Red gemstone ring, likely synthetic ruby or red spinel

Ruby: corundum (Al₂O₃); spinel: MgAl₂O₄; exact identity requires testing

Raw Topaz

Aluminum Silicate Fluoride Hydroxide, Al2SiO4(F,OH)2

Green Aventurine

Quartz with fuchsite inclusions (SiO2)

Synthetic Sapphire and Ion-X Glass

Single-crystal Alumina (Al2O3) and Ion-strengthened Aluminosilicate Glass

Smoky Quartz

Silicon Dioxide (SiO2)

Amethyst gemstone ring

Quartz, purple variety — SiO₂

Blue Sapphire

Corundum (Al2O3) with traces of Iron and Titanium

Small blue cut gemstone, possibly synthetic spinel or glass; species cannot be determined from the photo

Undetermined; blue synthetic spinel (MgAl₂O₄) is one possibility

Faceted colored gemstones, likely synthetic corundum or glass imitations

Not identifiable from the image; possible synthetic corundum (Al₂O₃)

Blue glassy mineral fragment, possibly sodalite or dyed/cobalt glass

Uncertain; likely sodalite (Na₈Al₆Si₆O₂₄Cl₂) if natural, but vivid blue color may indicate cobalt-colored glass

Pink faceted gemstone, likely synthetic or treated quartz

Quartz, silicon dioxide (SiO₂); exact identity cannot be confirmed from the image

Goldstone (with Tiger's Eye and Quartz)

Aventurine glass (Synthetic SiO2 with Cu inclusions)

Dyed or synthetic turquoise-blue glass-like specimen

Likely man-made colored glass or resin; exact identification requires testing

Tumbled amethyst

Quartz, crystalline silicon dioxide (SiO₂), purple variety colored mainly by iron impurities and irradiation

Purple faceted gemstone, likely amethyst or synthetic colored corundum

Amethyst: quartz (SiO₂); possible alternative: purple corundum (Al₂O₃) or glass

Emerald in Matrix

Beryl (Be3Al2Si6O18) with trace amounts of Chromium/Vanadium

Opalite

Synthetic Opalized Glass (SiO2 + additives)

Silicon Carbide (Carborundum)

Moissanite (SiC), though mostly synthetic

Tumbled hematite

Hematite (Fe₂O₃), commonly sold as “magnetic hematite” when synthetic or magnetized

Red faceted gemstone, possibly synthetic ruby or red glass

Unidentified red gem; ruby is corundum (Al₂O₃), while glass is amorphous silicate

Green gemstone ring (likely synthetic or imitation emerald)

Possibly emerald, beryl (Be₃Al₂Si₆O₁₈); the photo cannot confirm the center stone’s identity or whether it is natural.

Blue-green cut gemstone, possibly aquamarine

Unconfirmed; aquamarine is blue-green beryl, Be₃Al₂Si₆O₁₈

Red gemstone ring; likely synthetic ruby or red glass

Undetermined from the image; ruby is corundum (Al₂O₃), while red glass is amorphous silicate

Blue gemstone ring, likely blue topaz or synthetic blue spinel

Likely topaz (Al₂SiO₄(F,OH)₂) or synthetic spinel (MgAl₂O₄); identification is uncertain from the image

Opalite

Man-made opalized glass

Blue Sapphire

Corundum (Al2O3)

Spinel

Magnesium Aluminum Oxide (MgAl2O4)

Rough White Zircon

Zircon (Zirconium Silicate, ZrSiO4)

Faceted yellow gemstone (possibly citrine or synthetic glass)

Undetermined; citrine is yellow quartz (SiO₂), but the image cannot confirm the material

Blue glass-like gemstone specimen (likely dyed or synthetic quartz)

Uncertain; possibly blue-dyed quartz or synthetic glass, not confidently identifiable from the image

Small clear faceted gemstone, possibly cubic zirconia

Unconfirmed; cubic zirconia (ZrO₂) is a possibility, but diamond or another colorless stone cannot be identified from this image alone
