Siegenite & Dolomite (ex Dr. Gary Hansen)

Item Description

Clusters of sharp, silvery bright siegenite crystals and light pastel-pink dolomite rhombs richly cover the matrix plate on this very fine combination specimen from the famous Sweetwater Mine of Missouri's Viburnum Trend. Scattered, golden chalcopyrite on the edges add color. This is older material and is seldom available in this quality. Siegenite is an extremely rare mineral from these mines and is found at its most significant here. Rather, it was. No finds I am aware of came out since the 1980s. This is a superb example from the Dr. Gary Hansen dealer stock.
