Deep, rich, purple Amethyst! I can't get enough of this beautiful quartz. I'm not sure I believe in all the healing properties of stones, but I know I feel great when I wear this one! The natural nuggets measure 20 - 35mm. The round beads in between are also amethyst, while the smaller spacers are peridot. The clasp and other components are sterling silver. Wear it in good health!
