Adularia moonstone, potassium feldspar (orthoclase, KAlSi₃O₈), possibly imitation or another white translucent gemstone

Goldstone

Aventurine Glass (SiO2 + Cu small inclusions)

Blue Goldstone

Aventurine Glass (Silicon Dioxide with metal inclusions)

Gray rock (possibly basalt or fine-grained granite)

Undetermined; no diagnostic minerals are visible

Polished jasper pendant

Soapstone Carving

Steatite

Chert (likely jasper/chalcedony-rich chert)

Microcrystalline quartz, SiO₂

Serpentine

Serpentinite (group of hydrous magnesium iron phyllosilicate minerals)

Cut gemstone ring, likely diamond

Diamond (carbon, C), faceted gemstone; exact stone identification is uncertain from the image

Polished red jasper beads

Jasper, microcrystalline quartz (SiO₂) colored mainly by iron oxides

Polished agate bead bracelet

Agate, a banded microcrystalline variety of quartz (SiO₂), likely mixed-color dyed or naturally colored chalcedony

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

Steatite (massive talc), Mg₃Si₄O₁₀(OH)₂; exact material cannot be confirmed from the image

Clear Quartz (Faceted)

Silicon Dioxide (SiO2)

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

Polished blue-green glassy slag or coated mineral fragment

Most likely man-made colored glass/slag; exact composition cannot be determined visually
