Jewelry Store

Since 1991, our gem of a jewelry boutique has nestled in the heart of Cape Town, around the corner from the historical Green Market Square, in the center of the famous St. George’s Mall. We are not far from the beautiful Company Gardens, Cape Town’s oasis right in the middle of town where one can take a walk and enjoy some sun, nature, and even feed the squirrels. There are many other hotspots around, which we would love to tell you about!

Tanzanite is a breath-taking blue-violet gemstone discovered in 1967 by a traveler, near the foothills of Tanzania’s Mount Kilimanjaro. This lustrous stone with its distinct, desirable colors, is a thousand times rarer than a diamond because it is found only within a 4-kilometer 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 among the firsts to identify Tanzanite jewelry as having high value and esteem and to begin designing exquisite pieces for Cape Town’s international visitors and local customers. Visit us, and take home a vibrant piece of Africa. Our Tanzanite stones are certified.

Cape Diamond Exchange offers you a vast selection of certified diamonds, including ‘fancy’ diamonds. Fancy diamonds have specialized 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 brilliance and fire perfected for YOU.
The diamond purchased can be set in our setting or we can custom-make a piece special for you.
All our Diamonds are certified, with a laboratory certificate from the European Gemological Laboratory (EGL) or the Gemological Institute of America (GIA).
