The history of diamonds is a history of numbers. The world’s diamonds, by and large, formed three billion years ago at depths of between 150 and 200 kilometres below the earth’s surface. There, the mercury peaks at over 1,000 degrees Celsius and the pressure, at approximately 50 kilobars, is 50,000 times the atmospheric pressure at the Earth’s surface. Only when these conditions came together could the world’s hardest, most durable and undoubtedly most beautiful mineral be formed.

The same conditions that produce diamonds also produce magma, which is created in the Earth’s upper crust and quickly expands. As it does, volcanic eruptions take place that push the magma – and the diamond-bearing rocks within it – towards the surface of the Earth. Some of the columns that form in this rush to the surface are known as kimberlite pipes (after the town of Kimberley, where diamonds were first discovered in South Africa). Through these pipes, diamonds are made accessible to miners.

For over 25 years, South African Diamonds, trading as Millennium Diamonds, has been sourcing, cutting, polishing and trading the very best in South African diamonds. It is our love for and loyalty to South Africa, one of the world’s richest diamond-bearing countries, that makes us unique. All of our stones are sourced in South Africa, cut and polished by South African artisans, and traded both within South Africa’s borders and beyond. And, most importantly, every single one is natural – a product of the Earth and its ancient and complex processes.

As we go about our work, our persistent focus is on excellence. Our diamonds are cut to perfection using techniques and technology of the highest quality and precision. The final piece is a magnificent and luminous legacy resting in the palm of your hand.
