9iddbrs ((COLEMANITE)), $20 MINIMUM BID, Boron Open Pit Mine, Boron, Kern County, California, 18 x 16 x 11 cm, Large Cabinet, | |
I weighed it and I think it was 6 lb. Here is a extra large Colemanite with a large cathedral like cavity filled with the spear shaped crystals. It looks undamaged and nothing is apparent but there may be crystal or so missing. But even with an optivisor it looks good. |
