Genius starts great work,

The Diamond Works Institute established in 2001, a true South African diamond expert.
A flagship operating facility based in the heart of Cape Town providing a glimpse into the processing of diamonds and jewellery through onsite demonstration.
Dedicated to standard excellence, The Diamond Works specialises in the highest quality diamonds and tanzanites in Southern Africa. Sharing the world and story of South African natural treasures is a unique experience and is offered through our signature Sparkling Tour.
For years diamonds have been coveted and have gained a reputation for pioneering an entire industry; putting Africa on the map for the highest quality diamonds in the world. But in 1967, the gem industry saw the birth of something new – Tanzanite.
South Africa has a rich history in mining diamonds, over a century and a half in uncovering sought-after gems. South Africa is considered a world authority in white diamonds.
It can take up to 250 tonnes of sand to be moved to find a single diamond and only 20% of all diamonds will be of gem quality.
The Diamond Works only selects the very best stones that meet The Diamond Works standard, reviewing Cut, Colour, Clarity, and Carat.
