Mammoth Mine, Mount Isa, Queensland, Australia
Small Cabinet, 7.0 x 6.0 x 3.0 cm
Thin, sharp crystals to 1.5 cm on copper-rich sulfide matrix makes for a dramatic display! Large crystalline chalcocites, on hard rock matrix, are just not common from any locality. This piece has some trivial damage when inspected closely (hence a lower price appears here than I expected when I bought it myself), but most crystals are to 1 cm and in good shape.
