All of our tanzanite is sourced directly from the mine and is cut and polished in-house with the latest cutting-edge technology and highly skilled craftsmen. During the cutting and polishing process the specialised craftsmen will examine the gemstone in order to determine the best cut and shape for the specific tanzanite. To determine the shape and cut of the gemstone is an extremely delegate process; if the gemstone isn’t cut perfectly it will have a negative impact on the value.
Tanzanite Cutting & Polishing
Before the diamond is cut a desired shape is marked on the gemstone showing where it needs to be sawn. The gemstone is then placed onto a dop stick with hot wax before it’s placed on a spinning wheel; this process is referred to as bruiting. Once, the tanzanite is rounded in the bruiting process the girdle is then formed. To make sure the gemstone is smooth all around another tanzanite stone on a dop stick is used to polish the corners off perfectly. Afterwards the tanzanite gemstone is cut into the preferred shape suggested by the gemstone specialist. Before, the gemstone undergoes polishing it is sent for a quality check to ensure the bruiting process went according to plan.
The tanzanite is then given to a skilful craftsman, who places the gemstone against a spinning wheel. During the polishing process, the gemstone is given its unique facets while being frequently checked by the cutter; they will make each facet is polished and aligned with the rest of the gem. After the polishing process, the tanzanite will be transported to the Tanzanite International grading facility, where the gemstones are checked for clarity, colour, cut and carat weight.
