Synthetic Material (Not A Rock Or Mineral)

Goldstone

Avventurina (Cu + SiO2 glass)

Red glassy cabochon, likely synthetic ruby or red glass

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

Likely weathered pebble or mineral fragment

Indeterminate; possibly quartz-rich stone, iron-stained feldspar, or a small chert fragment

Blue-green faceted gemstone, likely turquoise or treated turquoise

Turquoise: hydrated copper–aluminum phosphate, CuAl₆(PO₄)₄(OH)₈·4H₂O; exact identification is uncertain from the image

Moissanite

Silicon Carbide (SiC)

Sapphire

Corundum (Al2O3)

Blue-green tumbled gemstone, likely turquoise or dyed turquoise

Turquoise: hydrated copper–aluminum phosphate, CuAl₆(PO₄)₄(OH)₈·4H₂O; identification is uncertain from the blurry image

Tumbled hematite

Hematite (Fe₂O₃), commonly sold as “magnetic hematite” when synthetic or magnetized

Green glass sphere/marble

Soda-lime glass (primarily SiO2, Na2O, CaO)

Clear quartz sphere

Quartz (silicon dioxide, SiO₂), likely rock crystal or low-grade milky quartz

Artificial Rock Face (Faux Rock)

Glass Fiber Reinforced Concrete (GFRC)

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

Diamond (or Cubic Zirconia)

Cubic Carbon (C) or Zirconium Dioxide (ZrO2)

Limonite (Iron Ore)

Limonite; FeO(OH)·nH2O

Faceted Gemstones (Mixed)

Various (e.g., Corundum, Beryl, Quartz, or synthetic equivalents)

Faceted glass-like gemstone object

Likely synthetic glass or cubic zirconia; exact material cannot be confirmed from the image

Crackled Quartz (Dyed)

Silicon Dioxide (SiO2)

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

Terrazzo (Synthetic Composite Rock)

Cementitious or Epoxy Resin-bound Aggregates

Lava Stone and Chakra Beads

Basalt (with various mineral/synthetic beads)

Silicon Carbide (Carborundum)

Moissanite (SiC)

Green iridescent glass cabochon or synthetic gemstone

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

Digital Multimeter (Synthetic Object)

Digital Multimeter (DMM)

Blue glass-like gemstone specimen (likely dyed or synthetic quartz)

Uncertain; possibly blue-dyed quartz or synthetic glass, not confidently identifiable from the image

Turquoise

CuAl6(PO4)4(OH)8·4H2O

Pearl and Garnet Glass

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

Decorative gemstone bracelet or jewelry

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

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

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

Likely clear quartz crystal (possibly cut/polished quartz or glass imitation)

Quartz, silicon dioxide (SiO₂)

Blue glassy mineral fragment, possibly sodalite or dyed/cobalt glass

Uncertain; likely sodalite (Na₈Al₆Si₆O₂₄Cl₂) if natural, but vivid blue color may indicate cobalt-colored glass

Painted River Rock

Painted Quartzite or Smooth Siltstone

Portable Ceramic Space Heater

Polished Acrylonitrile Butadiene Styrene (ABS) Plastic with Ceramic Heating Elements

Yellow faceted gemstone, likely citrine or synthetic glass

Citrine (quartz, SiO₂) is the leading natural possibility; visual identification is uncertain from the photograph

Gold-colored gemstone ring, likely citrine or glass imitation

Indeterminate from image; possible quartz (SiO₂) or yellow glass set in gold-colored metal

Raw ruby (corundum)

Ruby variety of corundum, aluminum oxide (Al₂O₃), colored chiefly by chromium

Dyed Agate

Silicon Dioxide (SiO2) with synthetic dyes

Painted Rock

Weathered Sedimentary Rock (Painted)

Carved labradorite fish

Labradorite, calcium-rich plagioclase feldspar (approximately (Ca,Na)(Al,Si)₄O₈)

Silicon Carbide (Carborundum)

Silicon Carbide (SiC)

Diamond (or Cubic Zirconia)

Carbon (C) or Zirconium Dioxide (ZrO2)

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)
