Item Description

A lovely, translucent, fine pink colored (manganese-bearing) rhombic crystal of Calcite with an attractive "stepped" appearance on the surface. The piece is in good shape, but it is contacted on the back / bottom where it was removed from the matrix. My guess is that this piece is from Naica, but the label only says Chihuahua, so I'm going to play it safe in case it's from a more obscure locality. Ex Kay Robertson Collection (#6401). Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record and the 50+ page article in the German Magazine "Mineralien Welt" November-December 2017).
