Overall Grade: Excellent

Comment: Here is a true rarity: Iridescence in a chrome tourmaline (GIA certified), sparkling with the color of the rainbow like opal. (probably a result of silica or liquid captured in the gem). Red, blue, green, yellow and gold come and go as the gem is turned. Mineral collector item and a beauty for a most unique pendant. We (not GIA)  have never seen this in chrome tourmaline before. It is sometimes found (and extra highly priced) in copper tourmaline.
