Caring for your tanzanite

Tanzanite

Tanzanite is found in only one place on earth:  Tanzania, East Africa.

The mining area is a tiny seven square kilometers in size.

Tanzanite is 1000 times rarer than diamonds.

Tanzanite usually has to be large to reach a deep saturated blue or violet. Stones that
weigh less than a carat are commonly a lighter periwinkle lavender color.

Tanzanite is the birthstone for December, and is also the gem for a 24th anniversary.
