Quartz on Malachite Ps. Calcite
Piedmont Mine, Yavapai Co., Arizona, USA
Thumbnail, 2.4 x 1.8 x 1.4 cm
Enchanting and unique thumbnail with great form and mineralogical interest, both. The original Calcite rhomb was replaced by Malachite, and that rhomb was subsequestly coated by Quartz, as if in a winter ice storm. The aesthetics of this 1.2 cm rhomb are terrific! Old collection material.
