Rarely do we get good specimens of this classic, replacement of azurite by sparkling bright chrysocolla. Atop it all, is a thin layer of drusy quartz which adds sparkle, and protects the underlaying blue chrysocolla as well. Most are large clusters, in any case. This is one of the very few thumbnail specimens I have seen of this material, and it really just leaps out for sheer color. It is complete all around, and is more than just a "small example," transcending to be superb thumbnail of a very hard thing to get. Ex Star van Scriver collection, in 1983, to thumbnail collector Ron Pellar. Joe Budd photos.
