Synthetic Or Natural Fiber

Smoky Quartz

Silicon Dioxide (SiO2)

Blue glassy mineral specimen, possibly blue topaz or aquamarine

Tentatively topaz (Al₂SiO₄(F,OH)₂) or beryl/aquamarine (Be₃Al₂Si₆O₁₈); identification is limited by severe image blur

Chipped Glass/Plastic Fragment

Silicon dioxide (SiO2) for glass (amorphous) or various polymer compounds for plastic

Cultured Marble (Synthetic)

Polymer-matrix composite (typically calcium carbonate in polyester resin)

Blue Goldstone

Synthetic glass with copper or cobalt/manganese inclusions

Nephrite Jade (Yellow Skin)

Nephrite (Ca2(Mg, Fe)5Si8O22(OH)2)

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.

Tumbled green beryl or glassy green gemstone

Likely beryl, Be₃Al₂Si₆O₁₈; possibly treated emerald or synthetic glass

Smoky Quartz

Silicon Dioxide (SiO2)

Synthetic Resin / Plastic Figurine

Synthetic Polymer (Copolymer of Polyethylene or Resin)

White cabochon gemstone, likely milky chalcedony or opalite

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

Smoky Quartz

Silicon Dioxide (SiO2)

Polished greenstone (likely nephrite jade)

Nephrite, a fibrous aggregate of tremolite–actinolite amphibole: Ca₂(Mg,Fe)₅Si₈O₂₂(OH)₂

Goldstone

Aventurine glass (Synthetic glass with copper inclusions)

Diamond

Native Carbon (C)

Smoky Quartz

Silicon Dioxide (SiO2)

Blue chalcedony or blue quartz bead bracelet

Ruby (Faceted)

Corundum (Al2O3 with Cr trace elements)

Opal

Hydrated Amorphous Silica (SiO2·nH2O)

Blue Sapphire

Corundum (Al2O3)

Rough White Zircon

Zircon (Zirconium Silicate, ZrSiO4)

Ruby (in jewelry)

Corundum (Al2O3 with Chromium traces)

Jadeite and Mixed Gemstones (Ruby, Sapphire, Emerald)

Jadeite (NaAlSi2O6), Corundum (Al2O3), Beryl (Be3Al2(Si6O18))

Ruby

Corundum (Al2O3 with Chromium trace)

Peridot gemstone pendant

Olivine, gem-quality forsteritic olivine (approximately (Mg,Fe)₂SiO₄)

Hematite

Iron(III) oxide (Fe2O3)

Diamond (faceted)

Diamond (Pure Carbon, C)

Goldstone

Aventurine glass

Staurolite (Cross Stone)

Staurolite (Fe2+2Al9Si4O23(OH))

Tiger's Eye (often misinterpreted as Gold Ore in this context)

Pseudomorph of Quartz after Crocidolite (SiO2)

Emerald

Beryl (Be3Al2(SiO3)6) with Chromium/Vanadium impurities

Opalite

Synthetic Glass (typically Silica/Magnesium based with metal additives)

Dyed pink agate slice

Agate (microcrystalline quartz, SiO₂), commonly chalcedony with artificial dye

Blue-green tumbled gemstone, likely turquoise or dyed turquoise

Turquoise: hydrated copper–aluminum phosphate, CuAl₆(PO₄)₄(OH)₈·4H₂O; identification is uncertain from the blurry image

Dyed Blue Agate

Silicon Dioxide (SiO2) - Microcrystalline Quartz

Tumbled blue chalcedony (likely dyed)

Cryptocrystalline quartz, SiO₂; chalcedony variety

Yellow-orange faceted gemstone, likely citrine or yellow topaz

Citrine: quartz, SiO₂; yellow topaz: Al₂SiO₄(F,OH)₂

Cubic Zirconia

Zirconium Dioxide (ZrO2)

Opalite

Man-made Glass (Synthetic Opalized Glass)

Smoky Quartz
