Mineral (Synthetic Glass)

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

Green Obsidian Sphere (man-made glass)

Vitreous Silica with Chromium/Iron additives

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

Opalite

Synthetic Opalized Glass (SiO2 + additives)

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

Spinel

Magnesium Aluminum Oxide (MgAl2O4)

Faceted yellow gemstone (possibly citrine or synthetic glass)

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

Faceted red gemstone, likely ruby

Corundum (Al₂O₃), red variety colored mainly by chromium

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

Blue Goldstone

Synthetic Avanturine Glass (or Aventurine Glass)

Goldstone

Man-made glass with copper inclusions

Opalite (likely man-made opalescent glass)

Opalite; not a true mineral, typically synthetic opalescent glass (silica-based)

Clear Quartz (faceted) / Diamond Simulant

Silicon Dioxide (SiO2) / Cubic Zirconia (ZrO2)

Goldstone

Aventurine Glass (SiO2 + Cu small inclusions)

Faceted purple-blue beads, likely synthetic glass or treated gemstone

Indeterminate; possible synthetic corundum, synthetic spinel, or dyed quartz (SiO₂)

Opalite

Synthetic Glass (Silica-based)

Opaline Glass (Opalite)

Synthetic Silicon Dioxide Glass

Green faceted gemstone, likely synthetic glass or peridot

Indeterminate from image; possible peridot (olivine, (Mg,Fe)₂SiO₄) or green synthetic glass

Blue Goldstone

Aventurine Glass

Tumbled tiger’s-eye

Quartz variety, fibrous golden-brown SiO₂ (pseudomorphic quartz after crocidolite)

Green faceted gemstone earrings

Undetermined; possibly green glass or synthetic emerald-type material, rather than identifiable natural emerald

Luminous Stone (Glow-in-the-dark Synthetic/Man-made Stone)

Strontium Aluminate tinted glass or resin (Crystalline silicate/oxide mix)

Green faceted gemstone, likely emerald or synthetic emerald

Beryl, Be₃Al₂Si₆O₁₈, colored green by chromium and/or vanadium; identity cannot be confirmed visually

Blue opalite (often sold as synthetic opal)

Opalite glass; amorphous hydrated silica if natural opal (SiO₂·nH₂O)

Opalite (likely man-made glass)

Opalite; amorphous silica glass, not a natural mineral

Opalite

Opalescent Glass (SiO2 + coloring agents)

Blue Goldstone

Man-made glass with cobalt and metal flecks
