Synthetic Glass (Often Categorized As A Simulated Mineral)

Goldstone

Aventurine glass (Synthetic glass with copper inclusions)

Opalite

Man-made opalescent glass (SiO2 + metal oxides)

Decorative opal-like turtle mosaic

Likely imitation or assembled opal material; exact stones cannot be confirmed visually

Opalite

Synthetic Glass (Hydrated Crystalline Silicon Dioxide simulation)

Blue Goldstone

Synthetic glass with cobalt and copper inclusions

Loose faceted colorless gemstones, likely quartz or glass-like mineral chips

Most consistent with quartz (SiO₂), though the photograph cannot exclude synthetic cubic zirconia or glass

Goldstone (Brown)

Aventurine Glass (Silicon Dioxide infused with Copper crystals)

Smoky Quartz

Silicon Dioxide (SiO2)

Opalite

Man-made Glass (Synthetic Opalized Glass)

Rough Citrine Quartz

Silicon Dioxide (SiO2) with ferric iron impurities

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

Yellow Jasper

Silicon Dioxide (SiO2) with Goethite/Iron oxide inclusions

Small clear crystal, possibly quartz or glass-like gemstone

Uncertain; likely quartz (SiO₂), but the image is insufficient to exclude man-made glass or cubic zirconia

Tumbled Clear Quartz and Citrine Points

Silicon Dioxide (SiO2)

Red Cubic Zirconia (Simulated Garnet)

Zirconium Dioxide (ZrO2)

Blue Goldstone

Aventurine glass (Synthetic borosilicate glass with cobalt and metallic inclusions)

Turquoise

CuAl6(PO4)4(OH)8·4H2O

Black spinel bead strand

Spinel, magnesium aluminum oxide (MgAl₂O₄)

Silicon Carbide (Carborundum)

Silicon Carbide, SiC

Goldstone

Avventurina (Cu + SiO2 glass)

Orgonite Pyramid (containing Amethyst and mixed minerals)

Silicon Dioxide (SiO2) in synthetic resin

Opalite (Synthetic Moonstone/Opal)

Synthetic Silica Glass

Blue cabochon gemstone ring

Uncertain; likely blue sapphire (corundum, Al₂O₃), blue topaz, or synthetic glass/spinel

Sapphire

Corundum (Al2O3)

Strawberry Quartz (Lepidocrosite/Hematite-Included Quartz)

Quartz (Silicon Dioxide) with Lepidocrosite or Hematite inclusions (SiO2 + Fe2O3 · nH2O)

Green Fluorite (likely synthetic or heat-treated for jewelry)

Calcium Fluoride (CaF2)

Turquoise

Hydrated copper aluminum phosphate, CuAl₆(PO₄)₄(OH)₈·4H₂O

Blue Sapphire (likely lab-grown or treated)

Corundum (Aluminum Oxide, Al2O3)

Pink tourmaline (rubellite)

Elbaite tourmaline, lithium sodium aluminum borosilicate: Na(Li1.5Al1.5)Al6(BO3)3Si6O18(OH)4

Opalite

Synthetic Glass / Man-made Opal Simulant

Sapphire (Blue)

Corundum (Al2O3)

Blue Goldstone

Synthetic glass with copper or cobalt/manganese inclusions

Blue resin-coated or dyed stone cabochon

Likely dyed chalcedony/agate (microcrystalline quartz, SiO₂); exact material is uncertain from the image

Blue Goldstone

Aventurine Glass

Red glassy cabochon, likely synthetic ruby or red glass

Uncertain; possible synthetic corundum (Al₂O₃, chromium-colored) or man-made glass

Smoky Quartz

Smoky Quartz (Silicon Dioxide - SiO2)

Blue Goldstone

Synthetic Aventurescent Glass (Cobalt-doped soda-lime glass)

Blue Sapphire (Synthetic or Man-made Glass Imitation)

Corundum (Al2O3) if natural; Lead-glass or Spinal if synthetic

Pink faceted gemstone, likely synthetic ruby or pink sapphire

Corundum (Al₂O₃), possibly chromium-colored ruby; synthetic origin likely

Red glass-like crystal, likely synthetic ruby or red glass

Uncertain from image; possible corundum (ruby), Al₂O₃, or synthetic glass

Red glassy mineral specimen, likely synthetic ruby or red spinel

Most consistent with synthetic corundum (Al₂O₃, ruby) or synthetic spinel (MgAl₂O₄); exact identification requires testing

Faceted gemstones, likely assorted quartz or glass-like gems

Not determinable from the photograph; possible quartz (SiO₂), topaz, or synthetic cubic zirconia
