“6.2 x 5 x 3 cm. Appealing, and unusual, combination piece of Shattuckite, Malachite, and Quartz. The Shattuckite, rich powder blue in color, occurs in excellent radial balls, on Quartz, and partially encased by a later generation of Malachite. The largest of the Shattuckite spheres is 2 cm across. In cross section, you can see the deep blue seed crystal, with the concentric layers radiating beautifully. A fine, and uncommon, combination piece. Ex. Charlie Key.
