Today, an appreciation for diamonds has evolved, not to only appreciate any diamond but to appreciate a truly rare diamond – The Diamond Works diamond. The Diamond Works Institute is considered a true South African diamond and jewellery expert. Established in 2001, it has evolved to be one of the most renowned diamond facilities in the region. The Diamond Works Institute extends its appreciation to tanzanite, a gem 1000 times rarer than diamonds. This exceptional stone represents the essence of Africa, and we whisper the tales of this stones journey from the ground to the showroom. Tanzanite is noted for its remarkably strong trichroism; appearing alternately sapphire blue, violet and burgundy depending on crystal orientation.
