The Mark of Rarity - Your Guarantee of Conflict Free Tanzanite

Finding a stone that has no connection to war, terrorism or undue suffering can be difficult. For this reason we strongly urge you to only purchase Tanzanite bearing the Tanzanite Foundation's Mark of Rarity TM.

This seal bears the icon of the Tanzanite Foundation and is your guarantee of quality, authenticity and a conflict-free source of Tanzanite.

The Mark of Rarity TM tag is licensed only for use by Tanzanite Foundation Manufacturing Members and Endorsed Stockists.

These parties agree to operate in accordance with legal and ethical employment practices. They are also required to adhere to strict safety standards across the board.

The Tanzanite Foundation is the owner and licensor of the Mark of Rarity TM.

Tanzanite Foundation Best Practice Principles:

  • Ethical and legitimate route to market.
  • Safe working conditions and fair working practices.
  • Environmental and social best practice.
  • Legal compliance.
  • Adherence to the Tucson Tanzanite Protocols.
