Synthetic Glass (Often Categorized As A Simulated Mineral)

Blue glass-like cabochon, likely dyed or synthetic material

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

Blue gemstone, likely iolite or blue sapphire

Iolite (cordierite, Mg₂Al₄Si₅O₁₈) or corundum (sapphire, Al₂O₃)

Emerald

Beryl (Be3Al2(SiO3)6)

Polished gemstone tower assortment

Primarily quartz varieties and simulants; apparent amethyst (SiO₂), rose quartz (SiO₂), clear quartz (SiO₂), fluorite (CaF₂), sodalite, malachite, and possibly dyed or composite stones

Blue cabochon gemstone ring

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

Blue gemstone, likely tumbled sapphire or blue spinel

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

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

Blue Goldstone

Aventurine Glass (SiO2 with Co and metallic inclusions)

Note: Item is a Synthetic/Man-made Object

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

Blue sapphire ring

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

Red corundum (ruby-colored polished crystal)

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

Faceted clear gemstone in a gold-tone ring

Likely colorless quartz (SiO₂); the image does not establish the stone identity, and glass or another gem is possible

Faceted gemstone in a jewelry setting

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

Faceted glass-like gemstone object

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

Dalmatian Stone

Dalmatian Stone (Felsic Igneous Rock)

Moonstone

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

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.

Faceted pale-green gemstone, likely prasiolite or green quartz

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