Various (e.g., Corundum, Beryl, Quartz, or synthetic equivalents)

Note on Image Identification: Textile

N/A (Anthropogenic material)

Red gemstone, likely ruby

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

Star sapphire ring

Corundum (Al₂O₃), likely asteriated sapphire

Faceted clear gemstone in a gold-colored setting

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

Goldstone

Aventurine Glass (Man-made)

Blue Goldstone

Man-made glass with crystalline copper/cobalt inclusions

Green faceted or cabochon gemstone (possibly glass or synthetic)

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

Blue-green faceted pendant stone

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

Synthetic Resin Charm (Seal Shape)

Polymer Resin with plastic glitter / Polyethylene terephthalate glitters

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.

Red gemstone ring (likely synthetic ruby or red glass)

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

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

Synthetic Convention Badge (Plastic/PVC)

Polyvinyl Chloride (PVC) / Polycarbonate

Clear Quartz (Faceted) or Cubic Zirconia / Glass imitation

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

Diamond (or Diamond Simulant)

C (Carbon) or synthetic equivalent

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

Opalite-style glass pendant

Man-made opalescent glass (not natural opal)

Faceted gemstone in a jewelry setting

Indeterminate from image; likely quartz, cubic zirconia, or another transparent faceted stone

Blue Opal Inlay (Simulated/Lab-created)

Hydrated Amorphous Silica (SiO2·nH2O) with polymer resin

Red gemstone ring, likely synthetic ruby or red glass

Unidentified red faceted stone; ruby is corundum (Al₂O₃)

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

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

Silicon Carbide (Carborundum)

Silicon Carbide, SiC

Faceted colored gemstones, likely synthetic corundum or glass imitations

Not identifiable from the image; possible synthetic corundum (Al₂O₃)

Emerald

Beryl (Be₃Al₂Si₆O₁₈), colored green by chromium and/or vanadium

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.

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.

Black faceted gemstone, possibly black spinel or synthetic material

Undetermined from image; candidates include spinel (MgAl₂O₄) or black sapphire (corundum, Al₂O₃)

Faceted dark gemstone, likely black spinel

Spinel, MgAl₂O₄ (visual identification is uncertain; black sapphire or other dark gems can look similar)

Cubic Zirconia

Cubic Zirconium Dioxide (ZrO2)

Opalite

Man-made glass (traditionally simulated Opal)

Red gemstone ring, possibly synthetic ruby or red glass

Unidentified red stone; ruby is corundum (Al₂O₃), but the image cannot confirm its identity

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

Faceted yellow gemstone (possibly citrine or synthetic glass)

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

Green faceted gemstone, likely synthetic glass or peridot

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

Sodium Polyacrylate (Superabsorbent Polymer)

Sodium Polyacrylate [-CH2-CH(COONa)-]n

Green gemstone ring, possibly emerald

The green stone may be emerald (beryl, Be₃Al₂Si₆O₁₈), but the photo cannot confirm its identity; the setting appears to be silver-colored metal.

Faceted blue gemstone, likely blue topaz or synthetic spinel

Topaz (Al₂SiO₄(F,OH)₂) or synthetic spinel (MgAl₂O₄); image insufficient for certainty

Black polished stone beads, likely black onyx or agate

Likely chalcedony (microcrystalline quartz, SiO₂); exact material cannot be confirmed from the image

Diamond-set gold ring

Diamond (crystalline carbon, C) set in a gold alloy; the metal and setting are manufactured

Synthetic Resin (Artificial Specimen)
