Colour refers to the blue in Tanzanite and its degree of violet saturation. The depth of colour ranges from Vivid to Pale, with a “B” or “v” preceding to indicate a predominance of blue or violet hues. The deeper the colour, the more precious the stone.
Note: in the rare circumstance that intensity of colour exceeds the Exceptional grade, it will be graded Exceptional.

Clarity refers to any natural flaws of inclusions in a Tanzanite. Tanzanite ranges from Internally Flawless to Heavily Included. The more flawless the stone, the more valuable it is.
Cut refers to the shape, facets and proportion of a Tanzanite. A ‘fine’ cut ensures that the stone’s facets reflect light to create maximum brilliance. The more precise the craftsman’s cutting, the more valuable the Tanzanite.
Carat is the term used to measure a Tanzanite’s weight. One carat has 100 points and weighs 1/5 of a gram. Two seemingly identical stones will have different carat weights if they vary in depth.
Buy only from a reputable jeweler. Confidence is your assurance that your Tanzanite is natural, has been accurately graded and has followed an ethical route to market. Don’t buy Tanzanite if you are not sure of it’s authenticity, value and provenance.
