Heights Mine, Durham, Weardale County
4.1 x 3.3 x 3.3 CM (miniature)
Perfect and well composed Fluorite from the Heights mine. This cute miniature has a prominent, well isolated and very sharp cube perched on top. The edges and corners are sharp and perfect on this, the luster is glasslike and the Fluorites are quite transparent. No visible damage. A good value for a small, choice classic British Fluorite with a quality well beyond typical.
Quartz on Chrysocolla and Malachite
Phelps Dodge Morenci Mine, Morenci, Copper Mt. Mining District, Greenlee
11.6 x 8.1 x 6.2 CM (cabinet)
A large colorful Copper secondary display specimen from an old find in Arizona. A druze of tiny clear Quartz crystals is covering many green Malachite balls and areas of bright blue Chrysocolla. The overall effect is sparkling and vivid in person. A sizable specimen from Morenci. The bulk of the matrix is layers of Chrysocolla in several shades of blue looking like a rich Turquoise. Some of those thin layers seem to be "gem Silica" that when thick enough is highly sought after for Lapidary. These layers are too thin for that and the surrounding Chrysocolla is quite brittle besides. The matrix has been properly stabilized to keep it from cracking as some Chrysocolla can do. This piece is early sixties vintage and simply eyecatching.
