Cape Diamond Exchnge Stor Front


Cape Diamond Exchange is a jewelry boutique offering a range of jewelry and unique handcrafted pieces, set and unset certified Diamonds and Tanzanite, and a superior selection of stones.

Cape Diamond Exchange was established in 1991. Located in the heart of Cape Town you can find us on the corner of St. Georges mall and Shortmarket Street, a short step from the cosmopolitan bustle on the cobbles of the historical Green Market Square.

"Since 1991 our gem of a jewelry boutique has nestled by the historical Greenmarket Square, started by my beloved father, Mr Poldy, a legendary authority in the international Diamond & Jewelry industries. It is now my pleasure to be running it and I welcome you to the family, and invite you to contact me for any future needs. We are always here for you."

Warmest Regards,
Aviva - Director

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).

fine jewelry never ages.

We wish that was the case for fine people, too!
But at least you can keep that ‘forever’ feeling by having your pieces professionally cleaned and re-polished.'
