Malachite on dioptase, Katanga, DRC
description: 2 3/8" tall This piece is a relative rarity. It displays malachite crystals on a matrix of dioptase. Malachite rarely forms crystals of this size. It often forms short acicular cyrstals which are so thin it is not possible to see their terminations with a stereomicroscope. Malachite crystals are also found at Tsumeb and Onganja, Namibia. Unlike the specimens from these two localities, this one consist of malachite crystals on a matrix which is covered by crystallized dioptase. It is both unusual and attractive.
