622 ts ((COLEMANITE)), $20 MINIMUM BID, Boron Open Pit Mine, Kramer Borate Deposit, Boron, Kern County, California, 6.5 x 5 x 2.5 cm, Miniature to small Cabinet | |
Here is an unusual specimen of Colemanite. The color is red brown which looks both internal and a coating on parts of the crystals. Also the crystals are a different habit than the spear or chisel shaped crystals. There were only a few of these in one box. Is probably a small and rare occurance. Undamaged except a small area near the edge but overall undamaged. Back is sawn and shaped, ex Jim Minette collection. |
