Mineral (Native Element)

Quartz-bearing feldspathic pegmatite

Pegmatite, chiefly quartz (SiO₂) and potassium feldspar (KAlSi₃O₈), possibly with mica

Copper-bearing rock (likely native copper in a green copper-mineral matrix)

Native copper (Cu), possibly with chrysocolla or malachite; exact identification requires testing

Pegmatitic pink feldspar–quartz rock

Granitic pegmatite; chiefly microcline/orthoclase feldspar (KAlSi₃O₈), quartz (SiO₂), and minor mica

Purple fluorite-bearing mineral specimen

Fluorite (calcium fluoride, CaF₂), possibly with quartz or chalcedony matrix

Rough Diamond

Diamond (pure Carbon, C)

Likely copper-bearing rock (identification uncertain)

Possibly native copper with copper oxides; the image is insufficient for a definitive identification

Lepidolite on Pegmatite

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

Likely native silver-bearing ore or metallic slag-like specimen

Uncertain from the photograph; possible native silver (Ag), but identification requires testing
