These are AA Grade, rough cut chrome diopside gemstones dangling from a sterling silver bail. The bails 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 24 x 10mm in size, not including the bail. No two pendants 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.
