Aurichalcite in Calcite
Ojuela Mine, Mapimi, Durango, Mexico
Small Cabinet, 8.5 x 4.6 x 3.9 cm
On a sliver of limonite matrix, is a plate of intergrown, lustrous and translucent, calcite rhombs, to 1.5 cm across. These are heavily invested with fibrous aurichalcite, resulting in a rich blue color. There is even a coating over the calcite rhombs of pastel blue, fibrous aurichalcite.. A fine display quality specimen with unusually good luster and a very even coloration to it, this is a good deal for the price, I felt as I tried to amortise to keep a nice larger piece under $1000
