Rare psuedomorph of royal blue Shattuckite that has replaced a number of Cuprite crystals. This of one of the rarer Tantara psuedomorphs, and one of only a very few I've ever seen. There are four larger crystals to 9mm in size, plus numerous small crystals. There are likely more small crystals hidden under the Chrysocolla, which can be easily air abraded away if desired. There are small amounts of Dioptase and Malachite in association. A true rarity!
