Smoky Quartz

Silicon Dioxide (SiO2)

Quartz (Smoky Quartz variant)

Silicon Dioxide (SiO2)

Quartz (Druzy / Goldstone Gemstone Cabochon)

Silicon Dioxide (SiO2)

Smoky Quartz

Silicon Dioxide (SiO2)

Opalite

Man-made Synthetic Glass (Silicon Dioxide with metal additives)

Blue Quartz / Glass Gemstone Pendant

SiO2 (Silicon Dioxide) or Synthetic Glass

Silicon Carbide

Silicon Carbide, SiC

Faceted clear gemstone in a gold-colored ring

Unidentified colorless faceted gem; possibly quartz, glass, or another transparent gem material

Faceted clear gemstone in a gold-colored setting

Unidentified transparent faceted stone; possibly quartz, glass, or another colorless gem

Opalite

Synthetic Glass (typically Silica/Magnesium based with metal additives)

Goldstone

Aventurine glass (Synthetic glass with copper inclusions)

Corundum (Pink Sapphire / Ruby)

Al2O3 (Aluminum Oxide)

Opalite

Synthetic Opalised Glass

Goldstone

Avventurina (Man-made Glass with Copper inclusions)

Blue Goldstone

Synthetic glass with cobalt and copper inclusions

Opalite

Synthesized glass / Silicon dioxide

Black onyx or black obsidian bead bracelet

Likely chalcedony (microcrystalline quartz, SiO₂) if onyx; alternatively volcanic glass (obsidian)

Opalite

Man-made Glass (Synthetic Opalized Glass)

Turquoise cabochon or turquoise-bearing material

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

Opalite-style pendant (likely synthetic glass, not natural opal)

Opalescent glass; commonly sold as “opalite” (not a recognized mineral species)

Opalite

Man-made opalescent glass (SiO2 + metal oxides)

Red cabochon gemstone ring (likely glass or synthetic stone)

Undetermined; the image does not establish a natural mineral identity

Faceted clear gemstone in a metal setting

Unidentified transparent faceted gem; possibilities include quartz (SiO₂), topaz (Al₂SiO₄(F,OH)₂), or glass—the image is insufficient for identification.

Opalite

Synthetic Glass (Hydrated Crystalline Silicon Dioxide simulation)

Blue Goldstone

Aventurine glass (Synthetic borosilicate glass with cobalt and metallic inclusions)

Red Cubic Zirconia (Simulated Garnet)

Zirconium Dioxide (ZrO2)

Decorative opal-like turtle mosaic

Likely imitation or assembled opal material; exact stones cannot be confirmed visually

Goldstone (Brown)

Aventurine Glass (Silicon Dioxide infused with Copper crystals)

Smoky Quartz

Silicon Dioxide (SiO2)

Blue glassy mineral specimen, possibly blue topaz or aquamarine

Tentatively topaz (Al₂SiO₄(F,OH)₂) or beryl/aquamarine (Be₃Al₂Si₆O₁₈); identification is limited by severe image blur

Tumbled Clear Quartz and Citrine Points

Silicon Dioxide (SiO2)

Rough Citrine Quartz

Silicon Dioxide (SiO2) with ferric iron impurities

Opalite (Synthetic Moonstone/Opal)

Synthetic Silica Glass

Green faceted gemstone earrings, likely synthetic emerald-colored glass or cubic zirconia

Undetermined; possible glass (amorphous silicate) or synthetic cubic zirconia (ZrO₂)

Loose faceted colorless gemstones, likely quartz or glass-like mineral chips

Most consistent with quartz (SiO₂), though the photograph cannot exclude synthetic cubic zirconia or glass

Goldstone

Avventurina (Cu + SiO2 glass)
