RM1467   Kernite

U.S. Borax Mine, Kramer Borate deposit, Boron, Kramer District, Kern Co., California, United States

This huge size kernite specimen is formed by some glassy and translucent cleavage crystals. It is a rare borate, named after the namesake California county where it was discovered. It is extremely rare in sharp crystals. These crystals are not formed in the borate deposit itself, but rather in the tanks that are used to dissolve the borax. Every few years the tanks are shut down for maintenance. Kernite and primary tincalconite crystals are found growing on the large stirring blades and the walls of the tank. From the former Renaud Vochten collection (label will be send to the buyer).


Size: 9.8 x 7.5 x 4.2 cm.
Found in 1986.

Ex-col. Renaud Vochten.

A specimen for systematic collectors... A large group of needle-like colorless crystals (prismatic) of artinite, forming aesthetic rosettes. But in this sample we highlight some aggregates of desautelsite crystals, a rare manganese and magnesium carbonate found in very few locations. They are orange crystals forming groups together with the artinite.
