Cubic Zirconia (as used in jewelry setting)

Zirconium dioxide (ZrO2)

Man-made Synthetic Material (Costume Faux Fur)

Synthetic Polymer (Polyester/Acrylic)

Cubic Zirconia

Zirconium dioxide (ZrO2)

Ruby (in costume jewelry context)

Corundum (Al2O3) with Chromium impurities

Blue cabochon gemstone, likely synthetic spinel or glass

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

Opalite

Synthetic glass / Opalized glass

The user-provided image does not contain a rock or mineral specimen

Red gemstone, likely ruby

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

Opalite (Synthetic Moonstone/Sea Opal)

Silicon Dioxide (SiO2) glass with metallic inclusions

Ruby (set in a ring; possibly synthetic or imitation)

Corundum, Al₂O₃; red color is typically caused by chromium

Opalite

Synthetic Opalised Glass

Rainbow Hematite / Magnetic Hematite

Iron oxide (Fe2O3) - often synthetic/coated for beads

Ruby (Raw Corundum)

Al2O3 (Aluminum Oxide)

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

Clear faceted gemstone in an ornate metal bracelet

Unidentified transparent faceted stone; possibilities include quartz (SiO₂), zircon (ZrSiO₄), or glass—image alone cannot distinguish them

Red gemstone, likely ruby

Corundum (Al₂O₃), colored red by chromium

Opalite

Synthetic Opalised Glass

Opalite (Man-made Glass)

Synthetic Opalised 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

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

Synthetic Opalite Glass

Blue-green faceted pendant stone

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

Opalite

Synthetic glass (SiO2 + impurities)

Rock Crystal (Clear Quartz)

Silicon dioxide (SiO2)

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.

Mood Ring Stone

Liquid crystal thermotropic polymer

Clear Quartz (Faceted) or Cubic Zirconia / Glass imitation

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

Silicon Carbide

Silicon Carbide, SiC

Opalite-style glass pendant

Man-made opalescent glass (not natural opal)

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

Opalite

Man-made glass (traditionally simulated Opal)

Asphalt / Road Aggregate

Bituminous Conglomerate (synthetic)

Green faceted or cabochon gemstone (possibly glass or synthetic)

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