Synthetic Glass (Often Categorized As A Simulated Mineral)

Hematite

Iron(III) oxide (Fe2O3)

Faceted red gemstone, likely synthetic ruby or red spinel

Possibly corundum (Al₂O₃, ruby) or spinel (MgAl₂O₄); identity cannot be confirmed from the image

Tumbled turquoise-like stone

Likely turquoise, hydrated copper aluminum phosphate: CuAl₆(PO₄)₄(OH)₈·4H₂O

Botryoidal hematite (specular hematite)

Hematite, Fe₂O₃

Polished turquoise cabochon pendant

Turquoise, hydrated copper-aluminum phosphate: CuAl₆(PO₄)₄(OH)₈·4H₂O; likely stabilized or matrix-bearing material

Cubic Zirconia

Zirconium Dioxide (ZrO2)

Blue Goldstone

Auraventurine (Synthetic glass with cobalt and copper inclusions)

Synthetic Faux Fur Fursuit

Polyacrylonitrile / Polyester (Synthetic Textile)

Ruby (Corundum)

Corundum (Aluminum Oxide with Chromium), Al2O3:Cr

Faceted yellow-brown gemstone earring

Likely citrine (quartz, SiO₂), though treated quartz or synthetic glass cannot be confirmed from the image

Painted River Rock

Painted Quartzite or Smooth Siltstone

Blue gemstone ring, likely sapphire

Corundum, Al₂O₃ (probable blue sapphire); surrounding stones may be diamonds or simulants

Pink/red faceted gemstone, likely synthetic corundum or glass imitation

Corundum (Al₂O₃), ruby/sapphire variety; exact identification requires testing

Iridescent polished/tumbled stone (likely coated quartz or glassy synthetic material)

Indeterminate; possibly quartz (SiO₂) with an artificial iridescent coating

Hematite

Hematite (Fe₂O₃), likely a polished specular hematite palm stone

Bismuth crystal

Bismuth (Bi), synthetic laboratory-grown crystal

Faceted purple gemstone, likely amethyst

Quartz (SiO₂), purple variety colored by trace iron and natural irradiation

Staurolite (Cross Stone)

Staurolite (Fe2+2Al9Si4O23(OH))

Pink corundum (likely synthetic or treated sapphire)

Corundum, Al₂O₃; pink coloration commonly from chromium or treatment

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

Blue Sapphire

Corundum (Al2O3)

Cubic Zirconia

Zirconium Dioxide (ZrO2)

Likely amethyst cabochon ring

Quartz, SiO₂; purple coloration from trace iron and irradiation

Staurolite (Fairy Stone)

Staurolite (Fe2+2Al9Si4O23(OH))

Likely blue sapphire ring

Corundum (Al₂O₃), likely sapphire; surrounding stones may be diamonds or colored gems

Lapis Lazuli

Lazurite-dominant rock, (Na,Ca)8(AlSiO4)6(SO4,S,Cl)2

Bismuth

Bismuth (Bi)

Man-made Synthetic Material (Not a rock or mineral)

Polyester (Polyethylene terephthalate) / Faux Fur

Blue Sapphire

Corundum (Al2O3 with trace Titanium and Iron)

Ruby

Corundum (Al2O3 with Chromium traces)

Ruby

Corundum (Al2O3 with Chromium trace)

Polished blue stone, likely sodalite or dyed agate

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

Diamond

Carbon (C)

Amethyst cabochon ring

Amethyst, purple quartz (SiO₂)

Colorless faceted gemstone, likely quartz (rock crystal)

Quartz, silicon dioxide (SiO₂); exact identification cannot be confirmed from the photograph

Limonite (Iron Ore)

Limonite; FeO(OH)·nH2O

Cubic Zirconia (Faceted)

Zirconium Dioxide (ZrO2)

Blue gemstone ring, likely lapis lazuli

Lapis lazuli: lazurite-rich metamorphic rock, chiefly (Na,Ca)8(AlSiO4)6(S,SO)2, commonly with calcite and pyrite

Blue sapphire (rough corundum)

Corundum, Al₂O₃; blue color commonly from trace iron and titanium

Smoky Quartz

Silicon Dioxide (SiO2)

Diamond (Faceted Colorless)

Diamond (Pure Carbon, C)

Smoky Quartz

Silicon Dioxide (SiO2)
