Malachite, a copper carbonate mineral, can be varying green hues ranging from pastel green to almost black. Mineral forms include the bazaar stalactitic pillars, shimmering masses, and reniform (kidney-shaped). It rarely crystalizes, but is often found as microscopic crystal crusts. Malachite can also be a pseudomorph of a different mineral or replace another mineral by taking over its form. Common malachite pseudomorphs are azurite and cuprite, as prismatic, tabular, re-entrant twins, or thin splinter forms.
Malachite has a long history with humanity spanning well over 6,000 years. Famous malachite pieces include a high quality 30 ton piece extracted from the Russian "Nadezhnaya" pit of the Mednorudyansky. The famed Malachite room of the Winter Palace in St. Petersberg, Russia holds a giant room filled with Malachite from pillars, to a giant malachite vase.
