A BIG specimen of a collector favorite from Arizona. In this case, instead of being on chrysocolla, the sparkly quartz crystals are on a layer of malachite, which is in turn on a layer of chrysocolla. These are usually seen in small specimens, but the area of crystallization here measures 12 cm in length - this is basically a big pocket that was removed intact! This is an old-timer, and hard to find, especially in a specimen this large and rich! Probably 40 years out of the ground, this one.
