A rare, crystallized shattuckite specimen! Crystals, such as this, are much more uncommonly seen from any deposit where this species is found, than druses and globular growths. These are actually pseudomorphs after malachite, I was informed. Nevertheless, this is the BEST locale for the species, for large crystals - and this specimen would host some of the larger ones that I know of. The crystals, to 3 cm, form an upside-down spray of elongated, acicular crystals atop a contrasting quartz matrix. THESE ARE very 3-DIMENSIONAL in person. The cluster is complete around the backside as well (showing crystals to 2 cm on the reverse, admixed with malachite). A major specimen, for both significance and display, this piece was illustrated in the JAN-FEB 2010 issue of ROCKS & MINERALS magazine, in the "Connoisseurs' Choice" Column, a recurring feature on a particular species and some of its significant known specimens. This was from the collection of noted dealer and miner, Charlie Key, also then in the Marshall Sussman collection.
