From deep in the foothills of Mount Kilimanjaro in Tanzania comes tanzanite, a gemstone with only a single known source that has become one of the most intriguing and desirable precious gemstones of modern times. It is a variety of the mineral zoisite and varies from blue, to violet, or purple in colour. Described as ‘a geological phenomenon’, tanzanite is 1,000 times more rare than diamonds. Tanzanite jewellery is extremely valuable and coveted, both for the gem’s rarity, as well as its beauty.


When buying tanzanite in South Africa, or anywhere else in the world, certification is of utmost importance. A tanzanite certificate of authentication is your peace of mind that the gemstone has been graded according to Tanzanite International grading standards, and that the characteristics you believe to be true for your tanzanite, are accurate and honest.
