Mina La Farola, Copiapo, Chile
A thin crust of crystalline Atacamite makes up this thumbnail specimen. The crystals that make up the crust are generally in very good condition and reach lengths of 0.2" (5 mm). The slender, spiky crystals have good orthorhombic form and show the classic deep green color and bright vitreous luster. As the crust has been removed cleanly from its base, there is no other material present. It is hot-glued onto a foam base that fits into a plastic specimen box.
