Natural Tanzanite & Diamond Geometric Ring

The Natural Tanzanite & Diamond Geometric Ring centres on a natural tanzanite - the blue-violet variety of the mineral zoisite, prized for its rare velvety colour that shifts between blue and violet in the light - cut as a square-cut stone, measuring roughly 3x3mm and held in a diamond-framed geometric open square.

This is a genuine natural tanzanite. Virtually all tanzanite is heat-treated to bring out its signature blue-violet colour - a standard, stable and permanent trade practice, disclosed here per AGTA guidance. Tanzanite is found in only one place on earth, the Merelani Hills of Tanzania, which makes it one of the rarest coloured gems you can own.

1/5 ctw of natural diamonds accents the design, disclosed with equal prominence to the natural tanzanite centre. The centre is natural tanzanite and the diamond accents are natural.

Tanzanite is a softer, more delicate gem (Mohs 6-7), so treat it with a little care: clean it with warm, soapy water and a soft cloth, never an ultrasonic or steam cleaner, and take it off for rough work or sport so it does not get knocked or scratched. Set in solid metal, never plated.

A meaningful gift. Tanzanite is the December birthstone and the gem of the 24th wedding anniversary. Its rare, single-source colour makes it a thoughtful choice for a December birthday, a milestone anniversary, or anyone drawn to blue-violet.
