Gold Nugget

Native Gold (Au)

Native Silver

Silver (elemental Ag)

Opalite

Synthesized glass / Silicon dioxide glass

Bismuth Crystal

Bismuth (Bi)

Pyrite

Iron Sulfide (FeS2)

Cabochon gemstone ring, likely smoky quartz or tourmaline

Unconfirmed quartz (SiO₂) or brown tourmaline (dravite); visual identification is inconclusive

Small metallic mineral fragment

Unidentified metallic sulfide or native-metal fragment

Mixed gemstone jewelry collection

Likely amethyst, rose quartz or pink tourmaline, smoky quartz, and dark tourmaline/onyx; exact identifications are uncertain from the image

Gemstone ring (stone not identifiable)

Unknown; the small central stone may be a colorless gemstone or glass, and the surrounding metal is gold-colored alloy

Quartz and Limestone Grouping

Silicon Dioxide (SiO2) / Calcium Carbonate (CaCO3)

Small gold-colored jewelry piece with clear stones

Likely a metal setting holding small faceted gemstones; the stones cannot be identified from the image.

Gold Nugget

Gold (Au)

Iron-stained quartz vein in altered host rock

Quartz (SiO₂) with iron oxides/hydroxides, likely hematite and goethite; host rock uncertain from the image

Bauxite

Bauxite (mixture of hydrous aluminum oxides: Al(OH)3 & AlO(OH))

Pallasite Meteorite

Pallasite (Stony-iron meteorite; Fe-Ni alloy with (Mg,Fe)2SiO4 olivine)

Faceted orange gemstone stud (possibly citrine)

Unconfirmed; possibly quartz (SiO₂), variety citrine

Garnet-set gold ring

Likely almandine garnet, Fe₃Al₂(SiO₄)₃; the image does not establish the stone’s identity or treatment

K(Li,Al)3(Al,Si,Rb)4O10(F,OH)2 (Lepidolite mica)

Quartz Vein

Silicon Dioxide (SiO2)

Likely silver-gray metallic ore fragment

Unidentified metallic mineral; possibly galena (PbS), but the image is insufficient for a confident identification
