Luminous Stone (Glow-in-the-dark Synthetic/Man-made Stone)

Strontium Aluminate tinted glass or resin (Crystalline silicate/oxide mix)

Green faceted gemstone, likely synthetic glass or peridot

Indeterminate from image; possible peridot (olivine, (Mg,Fe)₂SiO₄) or green synthetic glass

Blue Sapphire (likely costume glass imitation)

Corundum (Al2O3) with iron/titanium impurities

Faceted transparent gemstone pendant

Likely cubic zirconia (zirconium dioxide, ZrO₂); possibly diamond or synthetic moissanite

Painted Rock

Weathered Sedimentary Rock (Painted)

Painted River Rock

Painted Quartzite or Smooth Siltstone

Costume Jewelry with Synthetic Gemstones

Synthetic Cubic Zirconia and Glass (SiO2 / ZrO2)

Faceted gemstone in a jewelry setting

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

Engineerged Quartz (Quartz Composite)

SiO2 (Silicon Dioxide) in a polymer resin matrix

Green faceted gemstone earrings

Undetermined; possibly green glass or synthetic emerald-type material, rather than identifiable natural emerald

Ruby / Red Corundum

Al2O3 (Aluminum Oxide with Chromium trace)

Clear Quartz crystals on a Matrix base (Geode fragment)

Silicon Dioxide (SiO2)

Pink faceted gemstone, likely synthetic or treated quartz

Quartz, silicon dioxide (SiO₂); exact identity cannot be confirmed from the image

Rhinestone (or glass crystal)

Silicon dioxide (if glass) / Various

Amber

Fossilized tree resin (Amorphous organic polymer)

Amber (Simulated/Faturan Style)

Resin mix (Likely Phenolic/Celluloid if synthetic, Succinite if natural)

Red gemstone ring, possibly synthetic ruby or red glass

Unidentified red stone; ruby is corundum (Al₂O₃), but the image cannot confirm its identity

Green faceted gemstone earrings, likely synthetic emerald-colored glass or cubic zirconia

Undetermined; possible glass (amorphous silicate) or synthetic cubic zirconia (ZrO₂)

Green gemstone ring, likely emerald simulant or jade

Uncertain; possible beryl (emerald, Be₃Al₂Si₆O₁₈) or jadeite (NaAlSi₂O₆), but the blurred image may show synthetic glass or another treated stone

Yellow-orange amber

Fossilized tree resin; amber is an organic mineraloid, not a true mineral

Amber

Succinate (Fossilized Tree Resin)

Red gemstone ring, likely garnet or synthetic ruby

Possibly almandine garnet (Fe₃Al₂(SiO₄)₃) or corundum/ruby (Al₂O₃); image alone cannot distinguish

Opalite

Synthetic Glass (Silica-based)

Opaline Glass (Opalite)

Synthetic Silicon Dioxide Glass

Opalite

Synthetic Glass (Simulated Opal)

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

Lapis Lazuli

Lazurite-dominant metamorphic rock, Na8[Al6Si6O24]n(S,Cl,SO4,OH)2

Jade bangle

Likely nephrite jade (fibrous amphibole, Ca₂(Mg,Fe)₅Si₈O₂₂(OH)₂); possibly jadeite (NaAlSi₂O₆)

Amber (Rough)

Amber (Fossilized Tree Resin, succinite)

Cubic Zirconia

Cubic Zirconium Dioxide (ZrO2)

Cubic Zirconia

Zirconium dioxide (ZrO2)

Amber

Fossilized tree resin; commonly derived from ancient conifers

Red faceted gemstone, likely synthetic ruby or red spinel

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

Green faceted gemstone, likely synthetic glass or chrome-dyed stone

Undetermined; possibilities include green tourmaline, synthetic emerald, glass, or dyed quartz

Red gemstone ring, likely ruby or synthetic ruby

Corundum (Al₂O₃), chromium-colored; natural versus synthetic cannot be determined from the photo

Red gemstone ring, likely synthetic ruby or red glass; exact stone cannot be confirmed from the image

Ruby (corundum, Al₂O₃) if natural; the setting appears to be silver-tone metal

Faceted gemstones, likely assorted quartz or glass-like gems

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

Opal cabochon or opal-like decorative specimen

Hydrated amorphous silica, SiO₂·nH₂O; likely synthetic or assembled opal material
