This gorgeous Malachite Bead Necklace is 22 inches long and composed of malachite beads, graduated in size from the largest beads (15 mm in diameter) to smallest (8 mm in diameter). In between the malachite beads are small green glass spacer beads. Not only is malachite beautiful in color, it also holds many healing properties, particularly in life-changing circumstances. It's found in and used in many countries, such as Namibia, the Congo and Zambia (per Wikipedia).
