Malachite is a shining copper ore with swirling islands of rich green color. Used since ancient Egyptian times as pigment for cosmetics, dyes and paints, malachite's primary use today is still ornamental. Popularized in modern times in 19th century Europe, it was worn as protection against the "evil eye." Much of today's fine malachite is mined in the Congo.

Tourmaline is a coveted stone that comes in a wide range of colors from black to pink, green and blue. Crystals which display more than one color together are common. A cross-section of a watermelon tourmaline crystal reveals green on the outside and pink within.
