Very often you would see ring designs with diamond cluster halos surrounding the Tanzanite not only to bring out the colour but also for added protection.

In a similar way to buying diamonds, Tanzanite has a grading system to determine the value and quality of the gemstone. Instead of four there are 5c’s; colour, carat, cut, clarity and confidence.


Colour refers to the intensity of colour and its degree of saturation. The depth of colour ranges from exceptionally blue-violet to pale-bluish. The deeper the colour, the rarer the gemstone and the most valuable.

Cut refers to the brilliance, proportions and finish of a Tanzanite. It ranges from excellent to poor. An excellent cut will have a maximum brilliance reflected from facets of the gemstone whereas a poorly cut Tanzanite would appear lifeless. Rounds, trillion and cushion cuts being the most popular.



Clarity refers to any natural flaws and inclusions in a tanzanite, ranging from flawless or eye clean to heavily included. The more flawless the tanzanite, the more valuable it is and it is extremely rare.
