Proustite from Chañarcillo Mining District, Atacama, Chile

Acquired this piece from Ralph Clark.


This became my favorite specimen in private hands when I first saw it in competition at the Tucson Gem & Mineral Show, and cemented my childhood fascination with proustite (bolstered by seeing this piece's big brother in the BM that spring). Years later when Ralph Clark was selling his collection, I visited the piece again and again, believing I was saying good-bye. Two months later, I received a call from Ralph and we worked out a way for this little gem to make its way to a home that will love, adore and cherish it.
