Synthetic Opalised Glass

Rock Crystal (Clear Quartz)

Silicon dioxide (SiO2)

Mood Ring Stone

Liquid crystal thermotropic polymer

Clear Quartz (Faceted) or Cubic Zirconia / Glass imitation

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

Blue cabochon gemstone, likely synthetic spinel or glass

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

Opalite

Synthetic Opalite Glass

Blue crystal pendant (likely blue glass or synthetic crystal)

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

Opalite

Synthetic glass (SiO2 + impurities)

Blue Goldstone

Man-made glass with crystalline copper/cobalt inclusions

Opalite

Synthetic glass / Opaque silicious glass

Opalite (Synthetic Moonstone/Sea Opal)

Silicon Dioxide (SiO2) glass with metallic inclusions

Gemstone Ring

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

Faceted clear gemstone ring, likely quartz or glass imitation

Unidentified colorless faceted material; quartz (SiO₂) is possible, but the image cannot distinguish it from glass or another gem

Opalite

Man-made glass (traditionally simulated Opal)

Opalite

Synthetic Silicon Dioxide (SiO2)

Green faceted or cabochon gemstone (possibly glass or synthetic)

Undetermined; possibilities include green beryl (Be₃Al₂Si₆O₁₈), quartz (SiO₂), or synthetic glass

Opalite Egg

Synthetic Glass (Simulated Opal)

Opalite-style glass pendant

Man-made opalescent glass (not natural opal)

Red gemstone, likely ruby

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

Blue Goldstone

Man-made glass infused with copper crystals

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.

Opalite

Synthetic opalescent glass

Opalite

Synthetic Opalized Glass

Blue-green faceted pendant stone

Undetermined; possibly synthetic glass or a blue-green gemstone such as topaz or quartz

Opalite

Synthetic Glass (Simulated Opal)

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

Cubic Zirconia (as used in jewelry setting)

Zirconium dioxide (ZrO2)

Goldstone

Aventurine Glass (Man-made)

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.
