Glassy, blocky Colemanite crystals lining a large vug. Colemanite from California is most commonly found as spikey, densely packed crystal groups and to have such jewel-like glassy crystals as these is uncommon. This was formerly in the Jim and Dawn Minette collection. Jim was the mine manager at Boron and had access to the very best minerals found there.
