Synthetic Glass (Often Categorized As A Simulated Mineral)

Citrine

Citrine (Silicon Dioxide, SiO2)

Faceted colorless gemstone, likely quartz (rock crystal)

Quartz, SiO₂

Goldstone

Aventurine glass

Tumbled amethyst

Amethyst, purple quartz (SiO₂)

Gemstone rings (stones not reliably identifiable)

The pale stone may be quartz or another translucent gem; the red stone may be ruby, garnet, or synthetic corundum. Image detail is insufficient for identification.

Cut purple gemstone, likely synthetic cubic zirconia or glass

Undetermined; possible cubic zirconia (ZrO₂)

Amber-set ring

Amber (fossilized plant resin; organic mineraloid), set in a metal ring

Ruby

Corundum (Al2O3 with Chromium traces)

Ruby (set in a ring; possibly synthetic or imitation)

Corundum, Al₂O₃; red color is typically caused by chromium

Pink-purple faceted gemstone ring (likely garnet)

Likely almandine–pyrope garnet, (Fe,Mg)₃Al₂(SiO₄)₃; identification from the image is uncertain.

Dyed Quartz Pendant

Silicon Dioxide (SiO2) with artificial dye

Blue glass-like bead or gemstone keychain ornament

Indeterminate; likely cobalt-blue glass or synthetic blue spinel, not identifiable as a natural mineral from the image

Green iridescent glass cabochon or synthetic gemstone

Likely synthetic glass; possibly coated synthetic quartz or lab-created green gemstone

Blue Topaz

Topaz [Al2SiO4(F,OH)2]

Amber (and Cubic Zirconia)

Fossilized Tree Resin

Cubic Zirconia (Faceted)

Zirconium dioxide (ZrO2)

Pearl (Imitation / Cultured Pearl)

Calcium carbonate (CaCO3) with conchiolin (or synthetic glass/plastic imitation)

Clear quartz crystal sphere

Quartz (silicon dioxide, SiO₂)

Opalite

Synthetic Glass, SiO2 base with metallic inclusions

Crackled Quartz (Dyed)

Silicon Dioxide (SiO2)

Smoky Quartz

SiO2 (Silicon Dioxide)

Blue-violet faceted gemstone, likely amethyst

Quartz (SiO₂), purple variety colored mainly by iron impurities and irradiation

Opalite (Man-made Glass)

Synthetic Silicon Dioxide Glass (SiO2 + metal oxides)

Colorless faceted gemstone (likely cubic zirconia)

Cubic zirconia, ZrO₂ (synthetic zirconium dioxide); possibly synthetic glass or lab-grown diamond

Strawberry Quartz (or Rose Quartz / Cherry Quartz)

Silicon Dioxide (SiO2) with Lepidocrocite, Hematite, or Goethite inclusions

Blue Goldstone

Aventurine Glass (SiO2 with Cobalt/Copper inclusions)

Polished pink corundum (likely treated ruby)

Corundum, aluminum oxide (Al₂O₃); ruby when red-to-pink from chromium

Goldstone

Man-made glass infused with copper crystals

Decorative gemstone bracelet or jewelry

Unidentifiable from the blurred image; likely colored glass or synthetic stones, possibly mixed gemstone beads

Pearl and Garnet Glass

Calcium Carbonate (CaCO3) for pearl; Silicon Dioxide (SiO2) for glass

Blue glass-like gemstone, likely synthetic spinel or glass

Uncertain; possibilities include synthetic cobalt-blue spinel (MgAl₂O₄) or cobalt-colored glass

Zirconia (Ceramic) & Ion-X Glass

Zirconium Dioxide (ZrO2) and Ion-strengthened Aluminosilicate Glass

Man-made Glass (Tumbled/Shaped)

Amorphous Silicon Dioxide (SiO2) with metal oxide colorants

Blue Sapphire

Corundum (Al2O3 with Cr, Fe, and Ti trace elements)

Likely blue glass or synthetic gemstone jewelry

Uncertain; possibly synthetic spinel, cubic zirconia, or blue glass

Faceted transparent gemstone, likely glass or cubic zirconia

Uncertain from image; possible cubic zirconia (zirconium dioxide, ZrO₂) or glass imitation

Ruby (Faceted)

Corundum (Al2O3:Cr)

Bismuth

Bismuth (Bi)

Amber

(C10H16O)n – an amorphous organic substance, primarily composed of polymerized isoprenoids.

Hematite

Iron(III) oxide (Fe2O3)

Emerald (green gemstone) pendant

Emerald, green variety of beryl (Be₃Al₂Si₆O₁₈); stones appear to be faceted and set in jewelry

Green glass-like cabochon, likely synthetic glass or resin

Unidentified green transparent material; possibly molded glass, synthetic spinel, or resin
