Rosasite, Malachite

A lovely small-cabinet specimen featuring rounded aggregates of rosasite intergrown with malachite from the famous Ojuela Mine. The piece displays velvety blue-green rosasite resting alongside rich green malachite covering the surface of a limonitic gossan matrix creating an attractive and well-balanced specimen. Rosasite is a relatively uncommon copper–zinc carbonate, good specimens are seldom encountered.

The Ojuela Mine is internationally renowned as one of the world’s finest sources of rosasite, having produced some of the most beautiful and well-developed specimens of the species. It is also celebrated for its remarkable diversity of secondary copper minerals. This specimen comes from the international collection of Peter Tarassoff.
