10iddbns ((KURNAKOVITE, ULEXITE)), $10 MINIMUM BID, Boron Open Pit Mine, Boron, Kern County, California, 3.5 x 2 x 2 cm, Miniature | |
These rare borate specimens were collected about 1976. My understanding was that they were only found at that time in the life of the mines. Here is a gemmy partial crystal with two side faces and the front and back crystal faces. Also a white mound of Ulexite on the Kurnakovite. They have been coated for protection against humidity by Minette. Jim Minette collected these. ex Jim Minette collection. |
