Terrazzo (Synthetic Composite Rock)
Cementitious or Epoxy Resin-bound Aggregates
Goldstone
Aventurine Glass (Man-made)
Painted River Rock
Artificially Coated Sedimentary Rock
Blue-green turquoise (probable)
Turquoise, hydrous copper aluminum phosphate — CuAl₆(PO₄)₄(OH)₈·4H₂O
Blue Goldstone
Man-made glass with crystalline copper/cobalt inclusions
Tumbled turquoise-like stone
Likely turquoise, hydrated copper aluminum phosphate: CuAl₆(PO₄)₄(OH)₈·4H₂O
Opalite
Synthetic Opalized Glass
Small colored gemstone or glass cabochons (uncertain)
Not identifiable from the image; the pieces may be colored glass or synthetic stones rather than natural minerals.
Dalmatian jasper
Orbicular rhyolite, commonly sold as Dalmatian jasper; quartz- and feldspar-rich volcanic rock with dark amphibole/biotite inclusions
Synthetic Wolf Plush (Non-mineral)
Canis lupus similis (Prop material: Polyester & Synthetic fibers)
Gold-colored gemstone ring, likely citrine or glass imitation
Indeterminate from image; possible quartz (SiO₂) or yellow glass set in gold-colored metal
Painted Rock
Weathered Sedimentary Rock (Painted)
Tumbled dalmatian jasper (likely)
Microcrystalline quartz/chalcedony with black amphibole or aegirine inclusions; commonly sold as “dalmatian jasper”
Faceted gemstone in a jewelry setting
Indeterminate from image; likely quartz, cubic zirconia, or another transparent faceted stone
Turquoise ring
Turquoise, hydrated copper–aluminum phosphate (CuAl₆(PO₄)₄(OH)₈·4H₂O)
Bituminous Coal
Organic-rich sedimentary rock (Complex hydrocarbons)
Synthetic Marbled Aggregate (Footwear Component)
Ethylene-vinyl acetate (Croslite™)
Faceted glass-like gemstone (likely synthetic quartz or cubic zirconia)
Identification uncertain; possibilities include synthetic quartz (SiO₂) or cubic zirconia (ZrO₂)
Colorless faceted gemstone (likely cubic zirconia)
Cubic zirconia, ZrO₂ (synthetic zirconium dioxide); possibly synthetic glass or lab-grown diamond
Colorless faceted gemstone, likely cubic zirconia
Cubic zirconia (zirconium dioxide, ZrO₂); visual confirmation is unavailable
Goldstone (with Tiger's Eye and Quartz)
Aventurine glass (Synthetic SiO2 with Cu inclusions)
Polished turquoise cabochon pendant
Turquoise, hydrated copper-aluminum phosphate: CuAl₆(PO₄)₄(OH)₈·4H₂O; likely stabilized or matrix-bearing material
Blue-and-white opalite sphere
Opalite (commercial synthetic or glass-based imitation; not true opal), typically silica glass or synthetic opalescent material
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.
Cubic Zirconia
Cubic Zirconium Dioxide (ZrO2)
Sandstone (likely Fossilized Wood or Concrete Simulacrum)
Arenite / Silicified Wood / Anthropogenic Concrete
Dyed Agate
Silicon Dioxide (SiO2) - variety Chalcedony
Purple cabochon gemstone, likely amethyst or purple sapphire/spinel
Indeterminate from image; possible quartz (SiO₂), corundum (Al₂O₃), or spinel (MgAl₂O₄)
Red gemstone ring, possibly synthetic ruby or red glass
Unidentified red stone; ruby is corundum (Al₂O₃), but the image cannot confirm its identity
Faceted purple-blue beads, likely synthetic glass or treated gemstone
Indeterminate; possible synthetic corundum, synthetic spinel, or dyed quartz (SiO₂)
Faceted blue gemstone, likely blue topaz or synthetic spinel
Topaz (Al₂SiO₄(F,OH)₂) or synthetic spinel (MgAl₂O₄); image insufficient for certainty
Artificial Rock Face (Faux Rock)
Glass Fiber Reinforced Concrete (GFRC)
Portable Ceramic Space Heater
Polished Acrylonitrile Butadiene Styrene (ABS) Plastic with Ceramic Heating Elements
Dyed or synthetic turquoise-blue glass-like specimen
Likely man-made colored glass or resin; exact identification requires testing
