Summary

Description
English: Quartz (Var.: Smoky Quartz), Microcline (Var.: Amazonite)
Locality: Smoky Hawk claim, Crystal Peak area, Teller County, Colorado, USA (Locality at mindat.org)
Size: 10.2 x 7.9 x 7.6 cm.
The Smoky Hawk claim has, since about 2006 or so, produced amazonite and smoky quartz combination pieces that rival the famous Tree Root Pocket material of the late 1990s. Some of them, such as this piece, are more aesthetic to my eye because they have not only the colorful amazonite in intense blue color, combined with smoky quartz: also, the best quartzes are generally gemmier and more translucent than the older Tree Root Pocket pieces. Moreover, on this piece, the quartzes (to 3 inches) shoot up so starkly and dramatically, that it "makes" the specimen. In many such combination pieces, the smoky quartzes are undersized compared to amazonite, or vice versa. Or, the two are often in a more jumbly aggregate that is pretty and of high quality, but not really the kind of stark geometry that I favor. I like specimens best when you have crystals on crystallized matrix, and the two geometries are as different in color and crystallography as you see here. Like nearly all such larger amazonite combination pieces, old and new finds both, this has a few repairs that would be considered par for the course, so long as they are well done and clean (which they are). This specimen sits nicely in the palm of your hand, spraying three-dimensionally to fill space. I obtained this specimen from the William Ferris collection by exchange, before that collection was sold off in 2007-2008. Mr. Ferris was the first owner, having acquired it directly from the company of Joe Dorris, the miner, several years previously. Since that time until now it has been in the Dallas collection of Rick Beard. Ex. Richardson Beard and William Ferris Collection.
