Andradite (Var: Topazolite) : Ca3Fe3+2[SiO4]3

Yellow Cat Mine, New Idria District, Diablo Range, San Benito Co., California, USA

This variety of Andradite is from the plentiful (and the only one known to date) find in the Yellow Cat Mine, November, 1998. Crystals are dodecahedra of very well-defined faces and edges; they are bright and have good color contrasting on a slightly bluish matrix.

Andradite (Var: Topazolite) : Ca3Fe3+2[SiO4]3

Yellow Cat Mine, New Idria District, Diablo Range, San Benito Co., California, USA
