Man Made Mineral Simulant (Glass)

Man-made Slag (Industrial Byproduct)

Anthropogenic Glassy Residue

Porcelain Tile (Sandstone-look)

Man-made Ceramic (resembling Quartz-rich Sandstone)

Man-made Dyed Aura Quartz

Silicon Dioxide (SiO2) with metallic coating/dye

Polished blue calcite sphere (tentative identification)

Calcite, CaCO₃; blue color generally results from trace impurities or inclusions

Ruby (Faceted)

Corundum (Al2O3:Cr)

Cut diamond-like gemstone

Likely cubic zirconia (zirconium dioxide, ZrO₂) or glass; natural diamond (carbon, C) cannot be confirmed from an image

Vesicular basalt (weathered scoria)

Scoriaceous basalt; chiefly plagioclase, clinopyroxene, olivine, and iron-titanium oxides

Colorless faceted gemstone, likely synthetic cubic zirconia

Cubic zirconia (zirconium dioxide, ZrO₂); natural diamond is a less likely alternative

Dyed Crackle Quartz

Silicon Dioxide (SiO2) with synthetic dye

Chert (Arrowhead/Artifact Fragment)

Microcrystalline or Cryptocrystalline Quartz (SiO2)

Rounded graywacke or sandstone cobble

Lithified clastic sandstone; likely quartz–feldspar–lithic grain aggregate in a silica or calcite matrix

Goldstone (Brown)

Aventurine glass

Dyed Dragon Vein Agate

Silicon Dioxide (SiO2) with artificial pigment

Hematite Beads

Hematite (Fe2O3)

Green Agate

Silicon dioxide (SiO₂)

Clear faceted gemstone, likely quartz (rock crystal)

Quartz, silicon dioxide (SiO₂); visual identification is uncertain because the stone is heavily faceted and photographed with flash

Polymictic conglomerate or breccia (possibly concrete-like aggregate)

Lithified polymictic gravel; clasts may include basalt, granite, quartzite, and other silicates

Crackle Glass (Simulated Gemstone)

Amorphous Solid (SiO2)

Diamond

C (Native Carbon)

Quartzite (Engineered Stone)

Silicon Dioxide (SiO2) based synthetic composite

Red glassy cabochon, likely synthetic ruby or red glass

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

Faceted yellow-brown gemstone ring, possibly citrine

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

Tumbled aqua glassy mineral specimen, likely chrysocolla or turquoise imitation

Uncertain from image; possible chrysocolla (hydrated copper aluminosilicate, variable composition) or dyed/man-made glass

Faceted colorless gemstone, likely glass or diamond imitation

Unidentified; possibly diamond (carbon, C) or cubic zirconia (zirconium dioxide, ZrO₂)

Man-made Synthetic Material (Costume Faux Fur)

Synthetic Polymer (Polyester/Acrylic)

Goldstone

N/A (Synthetic Glass with Copper Inclusions)

Pet Rock (Man-made Quartzite or Granite Cobble)

Silicon dioxide (SiO2) mixture; commonly composed of Quartz, Feldspar, and Mica

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

Man-made Ceramic / Clay Figurine

Aluminosilicate Ceramic (Processed Clay)

Sapphire

Corundum (Al2O3)

Cubic Zirconia (CZ)

Zirconium dioxide (ZrO2)

Man-made Synthetic Material (Not a rock or mineral)

Polyester (Polyethylene terephthalate) / Faux Fur

Dyed Quartz Geode

Silicon Dioxide (SiO2) with artificial pigment

Faceted Clear Gemstone (Likely Quartz or Cubic Zirconia)

Silicon Dioxide (SiO2) or Zirconium Dioxide (ZrO2)

Faceted Clear Quartz or Diamond Simulant

Silicon Dioxide (SiO2) if Quartz or Cubic Zirconia (ZrO2) if Synthetic

Blue Zircon

Zircon (Zirconium Silicate - ZrSiO4)

Diamond ring

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

Conglomerate

Conglomerate Rock (Paraconglomerate)

Silicon Carbide (Carborundum)

Moissanite (SiC)

Green glassy mineral specimen, likely rough emerald or green fluorite

Tentatively beryl (Be₃Al₂Si₆O₁₈), emerald variety; synthetic/man-made glass cannot be excluded from the photograph

Colorless faceted gemstone, likely glass or cubic zirconia

Uncertain; possible cubic zirconia (zirconium dioxide, ZrO₂) or synthetic glass

Colorless faceted gemstone, likely cubic zirconia

Cubic zirconia (synthetic ZrO₂), possibly glass or quartz
