All tanzanite is certified in accordance with the Tanzanite International Grading Standard, reassuring the owner of its quality of colour, clarity and cut as well as its authenticity.
TANZANITE JEWELLERY AUTHENTICATION
A rare and beautiful creation from Africa, each unique tanzanite comes with a certificate of authentication. The certificate not only assures that the gemstone has been ethically sourced from the foothills of Kilimanjaro, but it also explains the cut, colour, clarity and carat weight of the tanzanite. The certification of each tanzanite is extremely important as is describes the unique characteristics of the gemstone, while establishing the authenticity. Before you decide to buy an exquisite tanzanite jewellery creation make sure you understand the content of the certificate.
A tanzanite certificate will look as follows:
When you purchase your one-of-a-kind tanzanite it will be accompanied by a number, which guarantees the authenticity of the gemstone. The number can be used to track down the origin of the tanzanite and ensure that the gemstone was sourced ethically from the foothills of Kilimanjaro. By using the number on the gemstone you will be able to view the entire background of the tanzanite.
Like a diamond and other gemstones a tanzanite’s weight is measured in the form of carats. This means that one carat tanzanite will weight approximately 200mg or rather a fifth of the gram. The higher the amount of carat weight, the more valuable and rare the tanzanite; a tanzanite larger than five carats is considered to be extremely valuable and rare.
When you speak of the shape of the tanzanite, you’re referring to the shape or form into which the tanzanite is transformed. A perfect example of the shape of a tanzanite is oval, round and cushion – some of these well-known shapes are more popular than other when it comes to tanzanite jewellery. In the end, it all depends on the personal preference of the person who wear it.
The size of a tanzanite is measured in millimetres and added to the certificate of authentication. The dimensions establish the length, width and height of the tanzanite. By having a look at the dimensions you would be able to estimate the size of the tanzanite.
To determine the amount of facets that wat cut and polished by a skilful craftsman, you will cut section on the certificate. This part of the tanzanite grading is established by handwork and not nature. The cut will be able to tell you how much light enters the table of the tanzanite and how much light leaves the gemstone. It’s therefore important that the cut of the tanzanite is done by a master cutter with years of experience. Like a diamond, a tanzanite is available in a variety of different cuts that bring out the brilliance of the gemstone.
One of the most spectacular characteristics of a tanzanite is the exquisite colour of the gemstone. A tanzanite is available in a wide selection of blue and purple hues; from a light lavender colour to dark blue, a tanzanite is truly mesmerising. The deeper and more intense the blue colour of a tanzanite, the more rare and valuable the gemstone. To determine the value of a tanzanite, the grading process starts at a violet colour and ends at a higher value blue colour.
A tanzanite diamond has internal inclusions called, “flaws” or blemishes that have an impact on the grading value of the gemstone. The value of the tanzanite depends on the amount of inclusion in the gemstone; the higher the amount of inclusion the less valuable the tanzanite. A tanzanite is graded from Internally Flawless to Included.
