Native Carbon (C)

Red faceted gemstone, possibly ruby (identification uncertain)

Ruby, if natural: corundum (Al₂O₃) colored by chromium

Blue faceted gemstones, likely blue sapphire

Corundum (Al₂O₃), blue varieties colored chiefly by iron and titanium

Pink faceted gemstone, likely synthetic cubic zirconia or pink sapphire

Uncertain from image; possible zirconium dioxide (cubic zirconia, ZrO₂) or corundum (pink sapphire, Al₂O₃)

Ruby (cushion-cut red gemstone)

Corundum, Al₂O₃; red color is typically caused by chromium

Dalmatian jasper

Orbicular rhyolite, commonly sold as Dalmatian jasper; quartz- and feldspar-rich volcanic rock with dark amphibole/biotite inclusions

Blue Sapphire

Corundum (Al2O3 with Cr, Fe, and Ti trace elements)

Opalite

Man-made Glass (Synthetic Opalized Glass)

White cabochon gemstone, likely agate or chalcedony

Cryptocrystalline quartz (SiO₂), probably chalcedony/agate; exact identification is uncertain from the overexposed image

Faceted gemstone ring, likely smoky quartz or garnet in a metal setting

Not determinable from the photograph; possible quartz (SiO₂) or garnet-group silicate

Yellow faceted gemstone earrings, likely citrine or yellow beryl

Citrine: quartz, SiO₂; possible yellow beryl: Be₃Al₂Si₆O₁₈

Man-made Jewelry Charm (Enameled Metal)

Not a natural mineral; composed of base metal alloy (likely zinc or brass) and epoxy resin/enamel.

Faceted green gemstone, possibly peridot

Uncertain from the image; peridot is gem-quality olivine, (Mg,Fe)₂SiO₄

Faceted colorless gemstone, likely quartz or glass imitation

Most plausibly rock crystal (quartz, SiO₂); identity is uncertain because the photograph shows only intense facet reflections

Rose Quartz and Cherry Quartz (Dyed Glass/Quartz)

Silicon Dioxide (SiO2) with inclusions/dye

Diamond (or Cubic Zirconia)

Carbon (C) or Zirconium Dioxide (ZrO2)

Opalite crescent pendant

Opalite (man-made opalescent glass; not a natural mineral)

Colorless faceted gemstone, likely cubic zirconia

Amethyst: quartz (SiO₂); possible alternative: purple corundum (Al₂O₃) or glass

Blue glass-like gemstone specimen (likely dyed or synthetic quartz)

Uncertain; possibly blue-dyed quartz or synthetic glass, not confidently identifiable from the image

Decorative opal-like turtle mosaic

Red corundum gemstone (likely synthetic ruby)

Ruby: corundum, aluminum oxide (Al₂O₃), chromium-colored; likely lab-grown material

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

Tumbled green beryl or glassy green gemstone

Likely beryl, Be₃Al₂Si₆O₁₈; possibly treated emerald or synthetic glass

Orange cabochon gemstone, likely amber or amber-like resin
