General Description

Beautiful specimens with a thin layer of chrysocolla sitting on top of a basal matrix, and variably associated with malachite and Psilomane! Specimens generally have a fairly thin banding of crystalline material on more substantial basal matrix! Invariably the specimens often also have dendritic features on the matrix surfaces! Excellent and very exciting material. Generally Speaking - Chrysocolla has a cyan (blue-green) colour and is a minor ore of copper. The material has a wide range of hardness between 2.5 to 7.0. It is of secondary origin and forms in the oxidation zones of copper ore bodies. Associated minerals are quartz, limonite, azurite, malachite, cuprite, and other secondary copper minerals. It is typically found as botryoidal or rounded masses and crusts, or vein fillings. Congo produces the most frequently available materials sold at Toprock but the material is also known from Namibia from time to time. Malachite is the more frequently associated mineral to the chrysocolla out of Congo. Natural specimens are not as commonly available as polished items, but the supply is highly variable. Price is grade dependant. Items are as shown.
