Malachite was used as a mineral pigment in green paints from antiquity until about 1800. The pigment is moderately lightfast, very sensitive to acids, and varying in color. The natural form was being replaced by its synthetic form, verditer, among other synthetic greens. It is also used for decorative purposes, such as in the Malachite Room in the Hermitage, which features a huge malachite vase, and the Malachite Room in Castillo de Chapultepec in Mexico City. “The Tazza”, a large malachite vase, one of the largest pieces of malachite in North America and a gift from Tsar Nicholas II, stands as the focal point in the center of the room of Linda Hall Library.
Archeological evidence indicates that the mineral has been mined and smelted at Timna Valley in Israel for over 3,000 years. Since then, malachite has been used as both an ornamental stone and as a gemstone
