Malachite is gemstone with a vivid green color and a bright, polished luster. Malachite also exhibits patterned coloration, banding, and cat’s eye or chatoyancy. Malachite is frequently used in jewelry because of its lively green color and beautiful striations along its surface. Most malachite jewelry is in the form of earrings, bracelets, and pendants, but it is not considered hard enough for engagement rings. Most malachite is cut en cabochon. It is hardly ever faceted due to its softness and cleavage.
