Learn about the grading of the stone using our buyers guide before making a purchase.

The Importance of Tanzanite Certification

We have made a Tanzanite buying guide to help you as you look to purchase this rare gemstone. Whenever you are buying Tanzanite you should make sure that your stone has been graded and comes with a ‘certificate of authenticity’, which will provide a full breakdown of information about the gemstone. A Tanzanite certification also guarantees that the stone was mined in an ethical and legal manner.
Another keynote that we’ll touch on in the Tanzanite buying guide is the quality scale. The Tanzanite Quality Scale is an internationally recognized system that accurately describes the color and quality of stones, assuring buyers of the quality and authenticity of their Tanzanite.

In a similar way to diamonds, Tanzanite is graded according to the 4C’s: ‘Color, Clarity, Cut and Carat Weight’. The higher the combination of these characteristics, the rarer and more valuable the stone. All our Tanzanite Experience stores offer Duty Free Shopping.

Refers to colour quality and its degree of saturation. The depth of colour ranges from exceptional to pale, with `B´or `V´ indicating predominance of blue or violet hues.


Clarity refers to any natural inclusion in a tanzanite. Tanzanite properties ranges from Internally Fluorescent to Heavily Included.


Cut refers to the tanzanite´s angles and proportions. An excellent cut means that the stone reflects light to create maximum brilliance


Carat is the term used to measure a tanzanite´s weight. One carat has 100 points and weighs 1/5 of a gram.

Certificate of Authenticity

Every Tanzanite gemstone or jewelry that is sold through The Tanzanite Experience comes with a Certificate of Authenticity.

By visiting one of our stores you know that you are in good hands and have the opportunity to purchase from a wide selection of high quality, appropriately priced and conflict-free Tanzanites. 


How to Care for your Tanzanite

As part of the tanzanite buying guide, we are going to show you how to take care of the precious gemstone. Unlike diamond, Tanzanite is a softer gemstone (similar to Emerald).

It makes some of the most stunning jewelry, but it does need to be handled with a little more care than you would with Diamond.
