These are AA Grade, rough cut chrome diopside gemstones dangling from sterling silver ear wires. The silver ear wires have just a hint of rhodium added to them. The addition of rhodium slows the tarnishing process, less polishing for you. These free form chrome diopside stones average 18 x 7mm in size, not including the ear wires. No two pair are exactly alike in size and shape. Such a rich vibrant green color. Chrome diopside is said to alleviate aggression and enhance love and commitment.
