This is a large plate of superb crystals of California colemanite, from the notable collection of Jim and Dawn Minette. What makes these crystals stand out, in addition to their sheer number on this large plate, is their superb, flashy luster - and, in places, even gemminess - more like a plate of good calcites than colemanites.
