Synthetic Glass

Clear faceted quartz-like gemstone

Probably rock crystal quartz (SiO₂), though the image may show synthetic glass or cubic zirconia

Goldstone (Red)

Aventurine Glass (Cupriferous glass)

Tumbled blue glass-like specimen, possibly dyed chalcedony or synthetic glass

Uncertain; possible dyed quartz/chalcedony (SiO₂), but appearance strongly suggests cobalt-blue glass

Faceted colorless gemstone, likely quartz (rock crystal) or synthetic glass imitation

Quartz: silicon dioxide (SiO₂), trigonal crystal system; exact identity cannot be confirmed visually

Cut colorless gemstone, likely quartz or glass imitation

Most plausibly rock crystal (clear quartz, SiO₂); synthetic glass cannot be ruled out from the image

Blue glassy mineral fragment, possibly dyed/cobalt-colored calcite or aragonite

Uncertain from image; vivid blue coloration may indicate treated calcite (CaCO₃), aragonite (CaCO₃), or synthetic glass

Rough Diamond (Uncut Diamond)

Native Carbon (C)

Green gemstone ring, likely emerald simulant or jade

Uncertain; possible beryl (emerald, Be₃Al₂Si₆O₁₈) or jadeite (NaAlSi₂O₆), but the blurred image may show synthetic glass or another treated stone

Black rectangular gemstone pendant, likely obsidian or black glass imitation

Most plausibly black obsidian (volcanic glass; SiO₂-rich), though the image cannot exclude synthetic glass or black onyx

Cat's Eye Moonstone (Simulated/Synthetic or natural Cat's Eye Quartz/Glass)

There is no single scientific name. The appearance suggests either: Moonstone (feldspar group), Cat's Eye Quartz (SiO2), Apatite (Ca5(PO4)3(F,Cl,OH)), or most likely a synthetic material such as Fiber Optic Glass or 'Opalite' (a type of glass).

Black faceted gemstone, likely spinel or black tourmaline

Most plausibly black spinel (MgAl₂O₄); visually similar possibilities include schorl tourmaline (NaFe₃Al₆(BO₃)₃Si₆O₁₈(OH)₄) or synthetic glass

Goldstone (Red)

Aventurine Glass (SiO2 + Cu)

Faceted Gemstone

Unknown transparent mineral, possibly Diamond (C), Cubic Zirconia (ZrO2), Quartz (SiO2), or Glass

Blue cabochon gemstone, likely synthetic spinel or glass

Undetermined; possible synthetic cobalt-blue spinel (MgAl₂O₄) or colored glass

Red faceted gemstone, likely synthetic ruby or red glass imitation

Possibly synthetic corundum (Al₂O₃:Cr³⁺); image alone cannot distinguish it from glass or another imitation

Mood Ring Stone

Liquid crystal thermotropic polymer

Clear Quartz (Faceted) or Cubic Zirconia / Glass imitation

SiO2 (if Quartz), ZrO2 (if Cubic Zirconia)

Red glassy cabochon, likely synthetic ruby or red glass

Uncertain; possible synthetic corundum (Al₂O₃, chromium-colored) or man-made glass

Diamond-set gold ring

Diamond (carbon, C) in a gold-alloy setting; the stone may be a diamond or a diamond simulant

Blue Goldstone

Man-made glass with crystalline copper/cobalt inclusions

Pink faceted gemstone, likely synthetic ruby or pink sapphire

Corundum (Al₂O₃), possibly chromium-colored ruby; synthetic origin likely

Gemstone Ring

Various (Likely Glass, Cubic Zirconia, or assorted semi-precious stones)

Opalite (Synthetic Moonstone/Sea Opal)

Silicon Dioxide (SiO2) glass with metallic inclusions

Blue crystal pendant (likely blue glass or synthetic crystal)

Not identifiable from the image; possibly synthetic quartz or glass, rather than a natural mineral

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

Gemstone rings (stones not reliably identifiable)

The pale stone may be quartz or another translucent gem; the red stone may be ruby, garnet, or synthetic corundum. Image detail is insufficient for identification.

Cut purple gemstone, likely synthetic cubic zirconia or glass

Undetermined; possible cubic zirconia (ZrO₂)

Opalite

Synthetic Silicon Dioxide (SiO2)

Blue Obsidian

Volcanic Glass (Amorphous)

Red gemstone ring (likely synthetic ruby or red glass)

Possibly corundum (Al₂O₃), chromium-colored; identity cannot be confirmed from the image

Likely blue glass or synthetic gemstone jewelry

Uncertain; possibly synthetic spinel, cubic zirconia, or blue glass

Opalite

Man-made glass (traditionally simulated Opal)

Red gemstone, likely ruby

Corundum (Al₂O₃), colored red by chromium; identity cannot be confirmed from the photo

Red gemstone ring, likely synthetic ruby or red glass

Unidentified red faceted stone; ruby is corundum (Al₂O₃)

Small colored gemstone or glass cabochons (uncertain)

Not identifiable from the image; the pieces may be colored glass or synthetic stones rather than natural minerals.
