Schlossmacherite
is a very rare secondary
mineral in the oxidized zone of a copper-bearing gold
deposit at the Emma Luisa gold mine, Guanaco district,
about 100 km east-northeast of Taltal, Antofagasta,
Chile. This is the only location in the world for Schlossmacherite. It is found as polycrystalline aggregates
and crusts of pale green to grayish green.

A
beautiful combination of two very rare
minerals: Ceruleite (blue) and Schlossmacherite
(green). Ceruleite is only found at
a few localities worldwide and Schlossmacherite
is found only at the Emma Luisa Mine, Guanaco, Santa Catalina, Antofagasta Province, Chile.
I love the combination of robin's egg
blue and moss green!
