Why is Tanzanite considered so rare?

Tanzanite is a 'single-source' gemstone, meaning it is found in only one small mining area in Tanzania. Its geological rarity makes it a thousand times rarer than diamonds.

Is your Tanzanite treated?

Like over 99% of Tanzanite on the market, our stones are gently heat-treated to remove brownish undertones and permanently enhance the beautiful violet-blue color. This is a standard, stable industry practice.
