Synthetic Glass (Often Categorized As A Simulated Mineral)

Faceted yellow-brown gemstone earring

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

Smoky Quartz

Silicon Dioxide (SiO2)

Blue-green faceted gemstone, likely turquoise or treated turquoise

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

Opal-like cabochon ring stone

Likely common opal (hydrated amorphous silica, SiO₂·nH₂O); exact material uncertain from the photograph

Cubic Zirconia (Jewelry Setting)

Zirconium Dioxide (ZrO2)

Faceted glass-like gemstone object

Likely synthetic glass or cubic zirconia; exact material cannot be confirmed from the image

Blue cabochon gemstone ring

Likely blue turquoise, glass-filled sapphire, or blue spinel; exact identification requires testing

Red corundum (ruby-colored polished crystal)

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

Yellow faceted gemstone earrings, likely citrine or yellow beryl

Citrine: quartz, SiO₂; possible yellow beryl: Be₃Al₂Si₆O₁₈

Blue Goldstone

Aventurine Glass (SiO2 with Co and metallic inclusions)

Blue sapphire ring

Corundum (aluminum oxide, Al₂O₃), likely heat-treated sapphire

Note: Item is a Synthetic/Man-made Object

Titanium-coated Stainless Steel (Fe-Cr-Ni-Ti)

Blue gemstone, likely tumbled sapphire or blue spinel

Corundum (Al₂O₃) if sapphire; alternatively spinel (MgAl₂O₄)

Faceted pale-green gemstone, likely prasiolite or green quartz

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

Small faceted gemstone, likely diamond

Diamond (crystalline carbon, C)

Dalmatian Stone

Dalmatian Stone (Felsic Igneous Rock)

Faceted gemstone in a jewelry setting

Indeterminate from image; likely quartz, cubic zirconia, or another transparent faceted stone

Smoky Quartz

Silicon dioxide with aluminum impurities (SiO2)

Dyed turquoise bead

Turquoise, CuAl₆(PO₄)₄(OH)₈·4H₂O; likely stabilized or reconstructed turquoise

Silicon Carbide (Carborundum)

Silicon Carbide (SiC)

Blue glass-like cabochon, likely dyed or synthetic material

Uncertain; possibly dyed chalcedony, synthetic spinel, or blue glass

Note on Image Identification: Textile

N/A (Anthropogenic material)

Green faceted bead strand, likely dyed or synthetic material

Uncertain; possibly green-dyed quartz, glass, or lab-created emerald-like material

Green faceted gemstone, likely emerald

Beryl, Be₃Al₂Si₆O₁₈, colored green by chromium and/or vanadium

Tumbled amber

Amber (fossilized plant resin; predominantly polymerized diterpenoid resin)

Strawberry Quartz

Silicon Dioxide (SiO2) with inclusions of Goethite or Hematite

Ruby

Corundum (Al2O3 with Chromium traces)

Silicon

Element Si

Moonstone

Adularia or Orthoclase (KAlSi3O8) or Albite (NaAlSi3O8), specifically with lamellar exsolution of albite and orthoclase.

Jadeite and Mixed Gemstones (Ruby, Sapphire, Emerald)

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

Sapphire (likely blue synthetic sapphire or blue glass in a ring)

Corundum (Al₂O₃), specifically the blue variety due to trace amounts of iron and titanium impurities. If synthetic, it would still be Al₂O₃.

Blue faceted gemstone ring, likely synthetic sapphire or blue topaz

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

Asphalt / Road Aggregate

Bituminous Conglomerate (synthetic)

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

Quartz, silicon dioxide (SiO₂)

Faceted blue gemstone, likely aquamarine

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