Tanzanite Gemstone Enhancement Note

Virtually all Tanzanite (zoisite) is heated to produce the violet-blue color that consumers desire so dearly.  The stability of this treatment is excellent and permanent.

Dr. Gem’s® Advisory on care

Avoid sudden temperature changes including steam cleaning and ultrasonic cleaners.

Jewels & Diamonds™ stocks many fine grades of Tanzanite, but supplies of the very finest grades are limited.

Jewels & Diamonds™ does stock some lab-created (synthetic) Tanzanite priced very reasonably. However, none are featured on our website.
