Synthetic Polymer (Polylactic Acid)

Amber

Succinicum (Succinite); C10H16O

Mother of Pearl (Nacre)

Nacre (Aragonite/Conchiolin), CaCO3 + Organic Polymers

Ruby (faceted gemstone in a ring)

Corundum, Al₂O₃; red color typically from trace chromium

Red corundum (ruby-colored polished crystal)

Corundum, aluminum oxide (Al₂O₃); red color is typically caused by chromium

Amethyst (Tumbled)

Silicon Dioxide (SiO2) with Fe3+ impurities

Blue-and-white opalite sphere

Opalite (commercial synthetic or glass-based imitation; not true opal), typically silica glass or synthetic opalescent material

Dark blue polished stone pendant

Indeterminate; possibly sodalite, lapis lazuli, or blue slag/glass-like material

Carborundum (Silicon Carbide)

Silicon Carbide (SiC)

Cubic Zirconia (Faceted)

Zirconium dioxide (ZrO2)

Silicon

Crystalline Silicon (Si)

Cubic Zirconia (Simulated Diamond)

Zirconium dioxide (ZrO2)

Polished amber (likely copal or amber)

Fossilized tree resin; amber is predominantly polymerized diterpenoid resin, while copal is younger, incompletely polymerized resin

Blue glassy-looking specimen, possibly dyed or coated mineral

Not identifiable from the photograph; possibilities include dyed quartz or glassy slag, but composition cannot be established visually.

Faceted clear quartz (rock crystal), likely a cut imitation or low-grade gemstone

Quartz, silicon dioxide (SiO₂)

Cut red gemstone in a gold ring

Likely ruby (corundum, Al₂O₃), though red spinel or garnet is also possible from the image

Polished blue stone, likely sodalite or dyed agate

Most consistent with sodalite (Na₈(Al₆Si₆O₂₄)Cl₂), though the image cannot confirm composition

Blue stone cabochon, likely lapis lazuli or dyed stone

Lapis lazuli: lazurite-rich rock, chiefly (Na,Ca)₈(AlSiO₄)₆(S,SO)₂; exact identification is uncertain from the image

Faceted blue gemstone, likely aquamarine

Aquamarine—blue beryl, Be₃Al₂Si₆O₁₈; identification is uncertain from the image alone

White cabochon gemstone, likely milky chalcedony or opalite

Chalcedony: microcrystalline quartz, SiO₂; appearance may also indicate synthetic opalite glass

Polished hematite

Hematite (Fe₂O₃), likely a tumbled iron-oxide specimen

Dyed Agate Geode

Silicon Dioxide (SiO2) with artificial pigment

Asphalt (Bituminous Concrete)

Bituminous mix / Anthropogenic conglomerate

Polished amber (likely copal or amber imitation)

Amber: fossilized tree resin, chiefly polymerized succinic resin; copal is younger, incompletely polymerized resin

Emerald (green gemstone) pendant

Emerald, green variety of beryl (Be₃Al₂Si₆O₁₈); stones appear to be faceted and set in jewelry

Blue faceted gemstone ring, likely synthetic sapphire or blue topaz

Uncertain from image; possible corundum (Al₂O₃) or topaz (Al₂SiO₄(F,OH)₂)

Dyed Purple Agate Sliced Tablet

Silicon Dioxide (SiO2), variety Chalcedony

Gemstone-set silver jewelry piece

Likely mixed faceted gemstones in a silver-colored metal setting; stones may include sapphire, ruby/garnet, and yellow sapphire or citrine, but the image is insufficient for species-level identification.

Faceted pale-green gemstone, likely prasiolite or green quartz

Quartz (SiO₂), likely prasiolite; identification is uncertain from the photograph

Blue-green turquoise (probable)

Turquoise — hydrated copper aluminum phosphate, CuAl₆(PO₄)₄(OH)₈·4H₂O

Hematite

Iron(III) oxide, Fe2O3

Blue Goldstone

Man-made glass with cobalt and metal flecks

Diamond (or Cut Gemstone / Cubic Zirconia)

Carbon (C)

Emerald

Beryl (Be3Al2(SiO3)6) colored by Chromium and/or Vanadium

Opalite

Synthetically produced glass (Silicon Dioxide with metallic inclusions)
