10iddbns ((KURNAKOVITE)), $10 MINIMUM BID, Boron Open Pit Mine, Boron, Kern County, California, 3 x 3 x 1.5 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 plate of small gemmy crystals. They have been coated for protection against humidity by Minette. Jim Minette collected these. ex Jim Minette collection. |
