The human precision with which the tanzanite is cut and its shape determines its value in the market. Read below to understand the ideal way a tanzanite is cut into, and also the various shapes a tanzanite is crafted to perfection.


It is critical for a Tanzanite to cut well, as it impacts not only on the brilliance and fire of the tanzanite but also on the overall quality. A poorly cut tanzanite can make the best quality look inferior, and often stones are cut to maximize weight and not beauty.

Tanzanites are the found in a variety of shapes and sizes. Though ovals and cushions are most common, rounds, and other shapes - emerald cuts, trillions, etc. also, make for great buying. It might also be interesting to note that the cut helps in determining the color of the tanzanite. Depending on the blue or violet color component, tanzanite can resemble the finest royal blue sapphire or hint at Amethyst.

How much does the cut of tanzanite determine its value? It is the brilliance, proportions, and finishing of the cut that does that. When the tanzanite’s facets reflect a significant amount of light, it indicates the maximum amount of brilliance. The precision (proportions and finishing) with which the stone has crafted dictates how valuable the Tanzanite will be.

The diagram below indicates the way a tanzanite is the crafted to perfection. In this chart, you shall understand the ideal proportion of a tanzanite. While ‘a’ is the width of the tanzanite, ‘b’ indicates the height of the tanzanite crown (one-third portion) and ‘c’ is the depth of the pavilion.

On the other side, you shall see the best way a tanzanite should be cut. The first and the second are tanzanite’s that have not been properly cut. Any light that enters the tanzanite does not illuminate the inside of the stone, and leaves the color of the stone weaker. The best cut tanzanite is the one that cut on the right level of depth and width. This allows for light to travel through the stone and leave from a proper vantage point, allowing for full illumination of the stone as well as proper coloring.
