Man Made Alloy (Metallic)

Likely metallic meteorite fragment

Undetermined; possibly an iron meteorite or stony-iron meteorite

Iridescent bismuth crystal

Bismuth (Bi), artificially crystallized and likely oxidized/coated

Likely galena-bearing sulfide specimen

Galena (PbS), possibly with pyrite or other sulfides

Goldstone (blue-goldstone–style glass) beads

Artificial aventurine glass, typically silica glass with copper inclusions; not a natural mineral

Copper-bearing rock, likely oxidized native copper ore

Native copper (Cu) with copper-oxide/carbonate minerals, possibly chrysocolla, malachite, and cuprite in a limonitic host

Basalt

Basalt (Mafic volcanic rock)

Sunstone

Andesine-Labradorite Feldspar ((Ca,Na)(Al,Si)4O8)

Silver (Jewelry form)

Native Silver (Ag)

Iron meteorite candidate

Likely an iron-rich meteorite, possibly a weathered octahedrite (Fe–Ni alloy); identification is uncertain from the image alone

Small dark rock fragment

Uncertain; possibly weathered basalt or slag

Native bismuth

Bismuth (Bi), commonly artificially crystallized

Probable galena

Galena (lead sulfide, PbS)

Crushed Stone / Gravel

Aggregatus saxum (variable mineral composition)

Pyrite

Iron Sulfide (FeS2)

Beaded gemstone bracelet, likely lapis lazuli and pale quartz/agate

Lapis lazuli: lazurite-rich rock, chiefly (Na,Ca)₈(AlSiO₄)₆(S,SO)₂; pale beads are uncertain

Iron meteorite (likely weathered octahedrite)

Fe–Ni kamacite–taenite alloy, possibly a Canyon Diablo-type specimen

Unknown dark mineral/rock fragment

Indeterminate; possibly a dark sulfide mineral or slag-like geological fragment

Tumbled quartz-rich pebble

Microcrystalline quartz (SiO₂), possibly milky quartz or quartzite

Synthetic Blue Aura Quartz

Silicon Dioxide (SiO2) with Metallic Infusion

Graphite

Graphite (Carbon, C)

Goldstone (likely blue-free synthetic goldstone pendant)

Synthetic aventurine glass; silica glass with dispersed metallic copper crystals

Man-made Green Quartz (Lab-grown or Treated)

Silicon Dioxide (SiO2) with artificial coloration

Green Aura Quartz (Titanium treated Kyanite or Quartz)

Silicon Dioxide (SiO2) or Aluminum Silicate (Al2SiO5) with Titanium/Metal Oxide coating

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

Gold

Native Gold (Au)

Yellow cabochon gemstone, likely citrine or yellow glass imitation

Quartz (SiO₂), if natural citrine; visual evidence is insufficient to exclude man-made glass or resin

Polished green-and-black banded cabochon (likely malachite imitation or dyed agate)

Uncertain; possible malachite (Cu₂CO₃(OH)₂), banded agate (SiO₂), or man-made glass

Green glass cabochon or tumbled stone

Indeterminate; likely man-made glass, possibly aventurine glass rather than a natural mineral

Pyrite

Iron Sulfide (FeS2)

Blue Goldstone

Aventurine Glass (Silicon Dioxide with metal inclusions)

Unidentified polished dark gemstone cabochon

Possibly hematite, obsidian, jet, or dark agate; image insufficient for a definitive identification

Sunstone

Aventurine Feldspar (Plagioclase Feldspar with inclusions)

Pyrulite (Pyrite / Chalcopyrite)

Iron Sulfide (FeS2) or Copper Iron Sulfide (CuFeS2)

Pyrite

Iron Sulfide (FeS2)

Goldstone (Red)

Aventurine Glass

Pyrite

Iron Sulfide (FeS2)

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

Colorless faceted quartz-like gemstone

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

Basalt

Basalt (comprising Plagioclase feldspar, Pyroxene, and Olivine)

Pyrite (Fool's Gold)

Iron Disulfide (FeS2)

Dark rounded pebble, likely basalt or slag

Probable fine-grained mafic rock; possibly basalt (plagioclase–pyroxene) or industrial iron/steel slag

Copper ore-bearing rock (likely malachite/chrysocolla in a sulfide-rich matrix)

Cuprite–malachite/chrysocolla mineralization; probable copper sulfides such as chalcopyrite in altered host rock
