Synthetic Glass

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

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

Red cabochon gemstone ring (likely ruby or red spinel; identity unconfirmed)

Possibly corundum (ruby, Al₂O₃) or spinel (MgAl₂O₄); visual identification alone cannot distinguish these from glass or synthetic stones.

Blue Goldstone

Man-made glass infused with copper crystals

Red cabochon gemstone ring (likely glass or synthetic stone)

Undetermined; the image does not establish a natural mineral identity

Red gemstone ring, likely synthetic ruby or red spinel

Ruby: corundum (Al₂O₃); spinel: MgAl₂O₄; exact identity requires testing

Goldstone

Aventurine Glass (Man-made)

Small blue cut gemstone, possibly synthetic spinel or glass; species cannot be determined from the photo

Undetermined; blue synthetic spinel (MgAl₂O₄) is one possibility

Faceted colored gemstones, likely synthetic corundum or glass imitations

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

Pink faceted gemstone, likely synthetic or treated quartz

Quartz, silicon dioxide (SiO₂); exact identity cannot be confirmed from the image

Red faceted gemstone, possibly synthetic ruby or red glass

Unidentified red gem; ruby is corundum (Al₂O₃), while glass is amorphous silicate

Green gemstone ring (likely synthetic or imitation emerald)

Possibly emerald, beryl (Be₃Al₂Si₆O₁₈); the photo cannot confirm the center stone’s identity or whether it is natural.

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.

Blue-green cut gemstone, possibly aquamarine

Unconfirmed; aquamarine is blue-green beryl, Be₃Al₂Si₆O₁₈

Red gemstone ring; likely synthetic ruby or red glass

Undetermined from the image; ruby is corundum (Al₂O₃), while red glass is amorphous silicate

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 Clear Quartz or Diamond Simulant

Silicon Dioxide (SiO2) if Quartz or Cubic Zirconia (ZrO2) if Synthetic

Faceted red gemstone, likely ruby

Corundum (Al₂O₃), red variety colored mainly by chromium

Goldstone

Man-made glass with copper inclusions

Cubic Zirconia (as used in jewelry setting)

Zirconium dioxide (ZrO2)

Opaline Glass (Opalite)

Synthetic Silicon Dioxide Glass

Gemstone ring (stones not identifiable from image)

Unknown; the ring appears to contain two yellow stones and one colorless stone, possibly faceted gemstones or simulants

Green faceted gemstone earrings

Undetermined; possibly green glass or synthetic emerald-type material, rather than identifiable natural emerald

Opalite

Synthetic Opalite (Man-made glass)

Small clear crystal, possibly quartz or glass-like gemstone

Uncertain; likely quartz (SiO₂), but the image is insufficient to exclude man-made glass or cubic zirconia

Opalite (Synthetic Opalized Glass)

Synthetic Silicon Dioxide (SiO2) glass

Red gemstone, likely ruby

Corundum (Al₂O₃), colored red by chromium

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

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

Red faceted gemstone, likely synthetic ruby

Corundum (Al₂O₃), chromium-colored; possibly flame-fusion synthetic ruby

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

Corundum, Al₂O₃; red color is typically caused by chromium

Gemstone ring (stone not identifiable)

Unknown; the small central stone may be a colorless gemstone or glass, and the surrounding metal is gold-colored alloy

Cobalt Glass Slug (Man-made Glass)

Amorphous Silica with Cobalt Oxide (SiO2 + CoO)

Red faceted gemstone, likely synthetic ruby

Corundum (Al₂O₃); ruby when red, possibly laboratory-grown

Red gemstone ring, likely garnet or synthetic ruby

Possibly almandine garnet (Fe₃Al₂(SiO₄)₃) or corundum/ruby (Al₂O₃); image alone cannot distinguish

Ruby ring

Corundum (Al₂O₃), red variety colored mainly by chromium

Opalite

Synthesized glass / Silicon dioxide glass

Black polished stone beads, likely black onyx or agate

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

Artisanal Glass Beads (Simulated Goldstone or Aventurine Glass)

Silicon Dioxide (SiO2) with metallic inclusions

Green cut gemstone, likely synthetic emerald or glass imitation

Undetermined; natural emerald is beryl (Be₃Al₂Si₆O₁₈), while the vivid, very uniform appearance may indicate imitation material

Red cut gemstone, likely synthetic ruby

Corundum (Al₂O₃); possibly lab-grown ruby or red glass imitation

Red/pink faceted gemstone, likely synthetic ruby or red glass

Corundum (Al₂O₃) if ruby; identity cannot be confirmed visually
