Tanzanite is a high profile, popular gem from Tanzania with a hardness of 6.5.
Colours range from a less expensive light purple to a fine quality deep bluish purple.
Price can vary due to the often erratic availability. Tanzanite is brittle and must be treated with care.
Do not clean it in an ultrasonic as it may fracture and avoid thermal shock.
