Mineral Simulant (Synthetic Glass)

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

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

Costume Jewelry with Synthetic Gemstones

Synthetic Cubic Zirconia and Glass (SiO2 / ZrO2)

Faceted colorless gemstone, likely cubic zirconia or quartz

Uncertain from photograph; cubic zirconia (ZrO₂) is the leading visual possibility, with quartz (SiO₂) as an alternative

Opalite crescent pendant

Opalite (man-made opalescent glass; not a natural mineral)

Diamond (or Diamond Simulant)

Carbon (C) - Native Element

Man-made Synthetic Material (Costume Faux Fur)

Synthetic Polymer (Polyester/Acrylic)

Amethyst quartz cluster

Quartz, SiO₂; purple variety amethyst

Colorless faceted quartz-like gemstone

Likely quartz (SiO₂), though the appearance may also indicate man-made glass or cubic zirconia

Cubic Zirconia (in Jewelry)

Zirconium Dioxide (ZrO2)

Milky Quartz

Silicon Dioxide (SiO2)

Cat's Eye Moonstone (Simulated/Synthetic or natural Cat's Eye Quartz/Glass)

There is no single scientific name. The appearance suggests either: Moonstone (feldspar group), Cat's Eye Quartz (SiO2), Apatite (Ca5(PO4)3(F,Cl,OH)), or most likely a synthetic material such as Fiber Optic Glass or 'Opalite' (a type of glass).

Pink/red faceted gemstone, likely synthetic ruby or pink sapphire

Corundum, aluminum oxide (Al₂O₃); likely lab-grown or treated material

Blue Sapphire (likely costume glass imitation)

Corundum (Al2O3) with iron/titanium impurities

Faceted colorless gemstone, likely quartz or glass imitation

Most likely quartz (SiO₂), though the strong glare and visible facet pattern could indicate cubic zirconia or lead glass

Ruby / Red Corundum

Al2O3 (Aluminum Oxide with Chromium trace)

Goldstone

Aventurine glass

Diamond ring

Diamond, crystalline carbon (C), set in a metal ring

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.

Serpentinite

Serpentinite (composed primarily of Serpentine group minerals, e.g., Antigorite, Lizardite, or Chrysotile)

Diamond

Carbon (C)

Cherry Quartz with Rose Quartz

Crystalline Quartz (SiO2) with glass-based synthetic components

Costume Jewelry Gemstones (Emerald-imitation and semi-precious beads)

BeCuAl6Si6O18 (Beryl structure), frequently simulated by glass or synthetic spinel

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

Blue-violet faceted gemstone, likely amethyst

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

Faceted yellow-brown gemstone ring, possibly citrine

Unidentified faceted gem; citrine is quartz (SiO₂), but the photo is insufficient for a reliable identification

Clear quartz crystal sphere

Quartz (silicon dioxide, SiO₂)

Decorative gemstone bracelet or jewelry

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

Opalite

Synthetic Opalite Glass (Silicon Dioxide)

Diamond (or Cubic Zirconia simulant)

Carbon (C) or Zirconium Dioxide (ZrO2)

Green iridescent glass cabochon or synthetic gemstone

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

Opalite

Synthetic glass (SiO2 + metal additions)

Pearl and Garnet Glass

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

Strawberry Quartz (or Sunstone / Tumbled Quartz)

Silicon Dioxide (SiO2) with Hematite/Lepidocrocite inclusions

Strawberry Quartz (Hematoid Quartz)

Silicon Dioxide with Iron Oxide inclusions (SiO2 + Fe2O3)

Ruby / Red Tourmaline

Corundum (Al2O3) or Elbaite (Na(Li1.5Al1.5)Al6(Si6O18)(BO3)3(OH)4)

Diamond (or Simulant)

Carbon (C) or various simulants (e.g., Cubic Zirconia)

Corundum (Pink Sapphire / Ruby)

Al2O3 (Aluminum Oxide)

Opalite

Synthetic Glass (Simulated Opal)

Colorless faceted gemstone, likely glass or cubic zirconia

Uncertain; possible cubic zirconia (ZrO₂) or quartz (SiO₂), but the image may show a man-made simulant

Likely blue glass or synthetic gemstone jewelry

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

Carborundum (Silicon Carbide)

Silicon Carbide (SiC) / Moissanite (natural form)

Garden Quartz (Lodalite)

Silicon Dioxide with various mineral inclusions (SiO2)
