Synthetic Glass (Often Categorized As A Simulated Mineral)

Hematite cameo or hematine imitation

Hematite (Fe₂O₃); possibly synthetic hematine or black glass

Yellow faceted gemstone, likely citrine or yellow beryl

Quartz (SiO₂), if citrine; beryl (Be₃Al₂Si₆O₁₈), if heliodor

Smoky Quartz

Silicon Dioxide (SiO2)

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 ring, likely synthetic spinel or glass; identity uncertain

Possibly synthetic blue spinel (MgAl₂O₄) or laboratory sapphire (Al₂O₃); the clear side stones may be cubic zirconia or glass

Tumbled labradorite beads

Labradorite, a calcium-rich plagioclase feldspar (approximately (Ca,Na)(Al,Si)₄O₈)

Painted River Rock

Artificially Coated Sedimentary Rock

Tiger’s eye

Quartz (SiO₂), fibrous pseudomorph after crocidolite

Imitation or Cultured Pearl Earrings

Calcium carbonate (CaCO3) or synthetic polymer/glass

Diamond

Natural Diamond (Carbon, C)

Emerald

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

Cabochon-cut ruby (corundum)

Corundum, Al₂O₃; red color is caused mainly by chromium

Silicon Carbide

Silicon Carbide (Moissanite / Carborundum), SiC

Painted Rock

Weathered Sedimentary Rock (Painted)

Colorless faceted gemstone, likely cubic zirconia

Cubic zirconia (synthetic ZrO₂), possibly glass or quartz

Sapphire

Corundum (Al2O3)

Smoky Quartz

Silicon Dioxide (SiO2)

Green cabochon gemstone pendant, likely turquoise or dyed green turquoise

Probably turquoise, CuAl₆(PO₄)₄(OH)₈·4H₂O; exact identification requires testing

Colorless faceted gemstone, likely cubic zirconia

Cubic zirconia (synthetic ZrO₂), possibly glass or white sapphire

Faceted Clear Quartz or Diamond Simulant

Silicon Dioxide (SiO2) if Quartz or Cubic Zirconia (ZrO2) if Synthetic

Blue Goldstone

Aventurine Glass

Malachite

Copper carbonate hydroxide [Cu2CO3(OH)2]

Ruby (varieties of Corundum)

Aluminum oxide (Al2O3) with Chromium traces

Blue topaz-style pendant gemstone

Likely blue topaz (Al₂SiO₄(F,OH)₂); the image cannot confirm the stone or whether it is natural or synthetic.

Clear faceted gemstone, likely quartz (rock crystal)

Quartz, silicon dioxide (SiO₂); visual identification is uncertain because the stone is heavily faceted and photographed with flash

Magnetite or Hematite-rich Ore

Magnetite (Fe3O4) or Hematite (Fe2O3)

Likely weathered pebble or mineral fragment

Indeterminate; possibly quartz-rich stone, iron-stained feldspar, or a small chert fragment

Faceted black gemstone, likely black spinel

Spinel, MgAl₂O₄ (identification from appearance is uncertain)

Ruby (or potential synthetic/imitation)

Corundum (Al2O3)

Pink faceted gemstone ring (stone uncertain)

Possibly tourmaline or glass; image alone cannot establish identity

Colorless faceted gemstone, likely cubic zirconia or diamond

Uncertain from image; cubic zirconia (ZrO₂) is a common diamond simulant, while diamond is crystalline carbon (C)

Gemstone ring (stones not identifiable from image)

Unknown; the ring appears to contain two yellow stones and one colorless stone, possibly faceted gemstones or simulants

Man-made Green Quartz (Lab-grown or Treated)

Silicon Dioxide (SiO2) with artificial coloration

Goldstone (aventurine glass)

Synthetic copper-bearing soda-lime glass; commonly sold as red goldstone

Red cabochon gemstone ring, likely synthetic ruby or red glass

Possibly corundum (Al₂O₃, chromium-colored); identity cannot be confirmed from the image

Dalmatian Stone

Dalmatian Jasper (a misnomer) / Perthitic Feldspar Rock

Faceted purple gemstone, possibly amethyst

Likely quartz (SiO₂), variety amethyst; identification is uncertain from the image

Opalite

Synthetic Fluorescent Glass (SiO2 + impurities)

Red faceted gemstone, likely synthetic ruby or red spinel

Ruby: corundum (Al₂O₃); spinel: MgAl₂O₄; visual identification alone is insufficient

Banded Black Onyx (Chalcedony)

Silicon Dioxide (SiO₂)

Fursuit (Synthetic Fur Specimen)

Canis anthropomorphus syntheticus

Corundum (variety Ruby/Sapphire)

Aluminum Oxide (Al2O3)
