PRODUCT INFORMATION
General Description
Beautiful specimens with a thin layer of Chrysocolla sitting on top of a basal matrix, and variably associated with Malachite and occasionally Psilomane. Specimens generally have a fairly thin banding of crystalline material on more substantial basal matrix. Invariably the specimens might 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.Libethenite - Generally Speaking - Only a handful of these specimens come up once or maybe twice a year out of the Congo! Mostly small sized specimens having variable degrees of crystalline exposures sitting on a dolomitic like matrix. Generally Speaking - Libethenite is a rare Copper Phosphate hydroxide mineral. It forms striking, dark green orthorhombic crystals. It was discovered in 1823 in Ľubietová, Slovakia and is named after the German name of that locality (Libethen). It is a secondary Copper Phosphate mineral found in the oxidized zone of Copper ore deposits. The Phosphate is often derived from the weathering of Apatite and other rock-forming phosphates such as Monazite and Xenotime. This mineral is sporadically available from the Congo but is exceptionally rare and very collectible! Absolutely stunning orthombic crystal clusters. Price is grade dependant. Items are as shown.
