Malachite is one of the most popular semi-precious or decorative stones and has been for many years. This is due to its beautiful, patterned bands of light and dark green, its availability and relatively low cost. It has been used in jewellery from the southwest as a beautiful accent or combined with Turquoise or Azurite. It is popular as mounted cabochons, pendants, beads, sculptures, boxes and can even be turned on a lathe to make goblets and candlesticks. Facetable crystals are extremely small since larger ones are too opaque. Malachite occurs in the oxidized portions of copper ore with Azurite and Cuprite. Malachite is available from many sources worldwide including Bisbee and Gila in Arizona, USA; New Mexico and Utah, USA, Zambia, Broken Hill, N.S.W., Australia, Tsumeb, Namibia, Nizhne-Tagilsk, Zaire, and immense masses up to 50 tons from Mednorudyansk, Russia.
