I love semi-precious stones - they are so interesting and unique - no two stones are alike. These stones are no exception. Each 18mm semi-precious bead looks like it has been hand painted, all painted with the same colors, but each one just a little bit different. The beads are square in shape, but set end to end in a diamond shape and then all hand knotted with a knot placed between each bead,and finished up with a Sterling Silver toggle clasp. Snakeskin Agate is said to possess the power to bring you peace of mind. You will have peace of mind when you wear this lovely, graceful necklace.
