Shimansky Jewellers sorting loose rough tanzanite next to a Tanzanite Trilogy Ring

Discover the allure

The rarest gem known to man, tanzanite was discovered in 1967 in the foothills of Mount Kilimanjaro, northern Tanzania. A thousand times more rare than a diamond, this magnificent gem can only be found along a 4km strip of land in Tanzania, which is the only known source of tanzanite in the world. It is believed that within the next decade this source will be depleted, adding to the special allure of tanzanite.

A variety of the mineral zoisite, tanzanite has been described as a “geological phenomenon.” It is uniquely trichroic, meaning it displays three different colours when viewed from each of its crystallographic axes, namely blue,violet and red. Once cut and polished, Tanzanite colour varies from rich royal blues to delicate shades of violet and hues of red.

Tanzanite being as rare as it is should be treated as such. Ranging between 6.5 and 7 on the Mohs scale of hardness, Tanzanite is not a gemstone we would recommend for an engagement ring or every day wear. However, perfect for an anniversary ring, dress ring, earrings or a pendant.

Selecting your unique Tanzanite jewellery creation

Because of its rarity and limited source, tanzanite is an immensely valuable stone. Knowing which characteristics to look out for in a tanzanite stone helps you make an informed purchasing decision. The two most important factors to consider when grading tanzanite, is colour and clarity, however, its cut and carat weight also play a significant role in its value.

Many consider tanzanite to have the finest shade of blue in the world; a hue that is even more impressive than the blue of a sapphire. Good quality tanzanite has a deep royal blue or violet colour, and the more intense the colour, the more rare and valuable the stone. Tanzanite colours range from royal blues and vibrant violets to paler, watery shades. The kaleidoscope of blue and violet hues with delicate shades of red and pink truly sets this gem apart.

Just like diamonds and other natural gems, tanzanite may also have inclusions that influence the stone’s clarity and value. The less natural inclusions in the stone, the higher its value, and the more rare the stone. Graded in a manner similar to that of diamonds, tanzanite ranges between Internally Flawless (IF) and Included (I1-3). Shimansky tanzanite never has a lower clarity than VVS (very, very slightly included), meaning no inclusions can be seen with the naked eye. The higher the clarity, the more intense the stone’s fire and brilliance.

It is extremely important that tanzanite be well cut, not just because it gives the stone more brilliance, but also because it has a big impact on the overall value. Tanzanite must be cut to emphasise and maximise its beauty. A poor cut can make even the highest quality tanzanite look inferior. Tanzanite stones are cut in many of the popular shapes usually associated with diamonds, however, the most popular cuts for tanzanite are cushion, trilliant, pear and oval. At Shimansky we have a wide range of tanzanite cuts available, each one determined by the individual stone’s unique characteristics. The Shimansky Ayanda Queen of Tanzanite earring, ring and pendant collection is known for its top quality, certified tanzanite with superior cuts and contemporary designs.
