Malachite often results from weathering of copper ores and is often found together with azurite, geothite, and calcite. Except for its vibrant green color, the properties of malachite are similar to those of azurite and aggregates of the two minerals occur frequently. Malachite is more common than azurite and is typically associated with copper deposits around limestones, the source of the carbonate. 1.32 lb, 5x2.5 inches
