BEN1 - Benitoite sold

Gem Mine, San Benito Co., California, USA
Cabinet - 11 x 10 x 4 cm

(click on an image to enlarge)

Old Benitoite specimen with exceptionally good coverage of crystals. There is a 1.2cm triple term at the lower right, and in the center is a 2cm triple terminated crystal, though one termination could be better exposed by removing some more Natrolite. This is out a collection built in the 1970s and it has not been cleaned at all since then, so likey could be improved with modern cleaning/preparation methods. There is also no damage except along the very edges and part of a ridge of matrix that rises up at the upper right. I've only ever seen a small number os specimens of this size with such dense coverage of Benitoite.
