Cutting & polishing of tanzanite
In the rough, tanzanite shows potential thanks to its attractive bluish colour, but once cut and polished, the gem is brought to life, displaying magnificent fire, brilliance and scintillation. Cut by a master craftsman, each single facet of the tanzanite gem is shaped by hand. When you purchase a tanzanite ring, tanzanite necklace, or tanzanite earrings from Shimansky, you can be certain that only the highest quality stones have been used, and that each stone has been cut and polished to maximise its beauty. All of Shimansky’s tanzanite is sourced direct from the mine and is cut and polished in-house in the Shimansky factory with the most cutting-edge technology and highly skilled craftsmen, after which it is set and transformed into breath-taking tanzanite jewellery creations.
The process of transforming tanzanite from rough to polished involves various steps:
The cobbed tanzanite is weighed and sorted into groups based on colour and size in order to determine value. Through a vigorous and necessary processing, optical and manual sorting system, the rough tanzanite gems are prepared for the stages that follow.
The tanzanite is then pushed against a lap (a spinning wheel) to polish the stone. Polishing gives the stone its final facets and it is during this stage that the gem comes to life. The process requires a huge amount of skill and concentration, and it is this part of the process where the stone is given its grandeur. The gem is meticulously checked by the cutter after each facet has been polished; he inspects each facet closely before moving onto the next one. After being polished, the tanzanite is ready to be sent to the Tanzanite International grading facility, where its colour, clarity, cut and carat weight will be graded. Once the grading is complete, the gem will either be sold as a loose stone, or it will be set in a beautiful jewellery creation. Tanzanite is a unique gem, and requires experience, skill and attention to detail in the cutting and polishing processes. To achieve the optimum cut, the cutter must give the gem his undivided attention, and as a result, it can take days to cut and polish a single stone. The result, however, is worth the effort. Tanzanite jewellery is not only a great investment, but is absolutely beautiful to wear. When buying tanzanite in South Africa, select a stone from a reputable jeweler that has been cut and polished to maximise its beauty and reveal its true potential.
The true value of a Shimansky jewellery creation is only realised when it is worn by the person it is meant for.
