Milky Quartz

Quartz (Silicon Dioxide, SiO2)

Blue topaz pendant

Topaz (Al₂SiO₄(F,OH)₂), likely treated blue topaz

Jade-and-cabochon fruit cocktail ring

Likely nephrite or jadeite (jade) leaves with orange/cream chalcedony or other cabochons; identification from the image is uncertain

Amber jewelry (possibly amber-colored glass or resin)

Amber — fossilized plant resin, chiefly composed of polymerized terpenoids; the pictured material cannot be confirmed from the image

Amygdaloidal Basalt

Mafic extrusive igneous rock with secondary mineral infills

Opalite

Synthetic glass (Opalite simulant)

Pyrite

Iron Sulfide (FeS2)

Bismuth crystal

Bismuth (Bi), commonly laboratory-grown

Pink Granite

Phaneritic Plutonic Felsic Igneous Rock (Granite)

Gypsum rosette cluster (desert rose)

Gypsum, calcium sulfate dihydrate (CaSO₄·2H₂O), rosette habit

Limonite-stained Gossan/Ironstone

Phaneritic Plutonic Rock (High-silica Felsic)

Orange Calcite

Calcium Carbonate (CaCO3)

Pyrite in Quartz

Silicon Dioxide (SiO2) with Iron Sulfide (FeS2)

Small metallic mineral grain, possibly native silver

Unconfirmed; native silver (Ag) is one possibility, but the photograph alone cannot distinguish it reliably from other metallic minerals or metal debris.
