Tanzanite is a breath-taking blue-violet gemstone discovered in 1967 by a traveller, near the foothills of Tanzania’s Mount Kilimanjaro. This lustrous stone with its distinct, desirable colours, is a thousand times rarer than a diamond because it is found only within a 4 kilometre radius of the few existing active mines. Cape Diamond Exchange offers an incomparable range of Tanzanites, both unset, and set in jewelry. Mr Poldy was the first to identify Tanzanite jewelry as having high value and esteem, and to begin designing exquisite pieces for Cape Town’s international visitors and discerning local clients. Visit us, and take home a vibrant piece of Africa. Our Tanzanite stones are certified by EGL (European Gemmological Laboratory).



Cape Diamond Exchange offers you a vast selection of certified diamonds, including ‘fancy’ diamonds. Fancy diamonds have specialised shapes, other than round, and different colors, other than white. Each diamond has a different ‘finger-print’ to any other, with its inclusions (clarity), cut, color, and carat weight. At Cape Diamond Exchange, you have so many options to spoil a loved one or yourself with the diamond that gives off a brilliance and fire perfected for YOU. All our Diamonds are certified, with a laboratory certificate from the European Gemmological Laboratory (EGL) or the Gemological Institute of America (GIA)
