The Importance of Tanzanite Certification

Our Tanzanite buying guide is here to help you through the selection and purchase of this rare gemstone. As you buy Tanzanite, you should make sure that your stone has been graded and comes with a Certificate of authenticity, which will give you a full breakdown of information about your gemstone.
Another key aspect covered in our buying guide is the quality scale. The Tanzanite Quality Scale is an internationally recognized system that accurately categorizes the color and quality of stones, assuring buyers of the quality and authenticity of their Tanzanite. A Tanzanite certification also guarantees that the stone was mined in an ethical and legal manner.
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.

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 has been optimally shaped to reflect light for a maximum brilliance

How to Care for your Tanzanite

As part of the Tanzanite buying guide, we are going to show you how to take care of this precious gemstone. Unlike diamond, Tanzanite is a softer gemstone and needs to be handled with a little more care (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 a Diamond.
