Man-made Green Quartz (Lab-grown or Treated)
Silicon Dioxide (SiO2) with artificial coloration
Orange glassy slag (industrial by-product)
Iron-rich silicate glass; composition varies, commonly Fe–Ca–Al silicate
Faceted color-change gemstone, likely synthetic alexandrite or glass imitation
Alexandrite: chrysoberyl, BeAl₂O₄; exact identification requires gemological testing
Possible weathered basalt or slag fragment
Basalt, chiefly plagioclase and pyroxene; identification is uncertain from the image
Cubic Zirconia (CZ) Jewelry
Zirconium dioxide (ZrO2)
Polished green-and-black banded cabochon (likely malachite imitation or dyed agate)
Uncertain; possible malachite (Cu₂CO₃(OH)₂), banded agate (SiO₂), or man-made glass
Rough Diamond
Native Carbon (C)
N/A - Man-made object (Jewelry Chain)
Antiqued or Oxidized Metal Chain (often Steel or Brass)
Serpentinite
Serpentinite (composed primarily of Serpentine group minerals, e.g., Antigorite, Lizardite, or Chrysotile)
Luminous Stone (Glow-in-the-dark Synthetic/Man-made Stone)
Strontium Aluminate tinted glass or resin (Crystalline silicate/oxide mix)
Blue glass-like heart pendant, likely synthetic blue spinel or colored glass

Sea Glass
Amorphous Silicon Dioxide (SiO2)
Blue Goldstone
Aventurine Glass (SiO2 with Cobalt/Copper inclusions)
Faceted clear gemstone (likely glass imitation or quartz)
Uncertain; appearance is consistent with colorless quartz (SiO₂), but the strong uniform brilliance may indicate cut glass or cubic zirconia
Clear faceted gemstone, likely cubic zirconia
Synthetic zirconium dioxide (ZrO₂), probably cubic zirconia; exact identification requires testing
Diamond (Set in jewelry)
Cubic Carbon (C)
Man-made Carved Stone (Scream Mask/Skull motif)
Carved Soapstone or Serpentine-rich rock

Red cabochon gemstone ring (likely glass or synthetic stone)
Undetermined; the image does not establish a natural mineral identity
Colorless faceted gemstone, likely cubic zirconia
Synthetic cubic zirconia (zirconium dioxide, ZrO₂); identity is visual and not definitive
Clear faceted gemstone, likely synthetic cubic zirconia
Cubic zirconia (zirconium dioxide, ZrO₂); visual identification is not definitive and diamond or synthetic moissanite are alternatives
Likely clear quartz crystal (possibly cut/polished quartz or glass imitation)
Quartz, silicon dioxide (SiO₂)
Diamond (or Diamond Simulant)
Native Carbon (C)
Diamond jewelry
Diamond (crystalline carbon, C)
Diamond (or Cubic Zirconia simulant)

Note: Item is a Synthetic/Man-made Object
Titanium-coated Stainless Steel (Fe-Cr-Ni-Ti)
Faceted blue gemstone ring, likely synthetic spinel or glass; identity uncertain
Possibly synthetic blue spinel (MgAl₂O₄) or laboratory sapphire (Al₂O₃); the clear side stones may be cubic zirconia or glass
Diamond ring
Diamond, crystalline carbon (C), likely a faceted mounted stone
Faceted clear gemstone, likely glass imitation or cubic zirconia
Uncertain; possibilities include cubic zirconia (zirconium dioxide, ZrO₂), quartz (SiO₂), or lead glass
