Diamond Formation

Diamonds were born in the throes of the Earth's creation at the heart of immense, continent-shaping volcanoes. The oldest diamonds are more than 3.2 billion years old. Hundreds of kilometres below the Earth's surface, pressures fifty thousand times the normal atmosphere, and temperatures of up to 1,300°C gave rise to their unique crystalline lattice structure.

Volcano erruption
Kimberlite, solidified volcanic magma, hides diamonds among its many other characteristic tracer minerals.
Diamonds form in molten rock under high pressure, 125 to 200km deep. Some rare diamonds may originate even deeper - 300 to 400km below the Earth's surface.
Powerful eruptions force magma through the Earth's upper mantle toward the surface at the speed of sound. The resulting cone-shaped kimberlite "pipe" can be mined as a rich source of diamonds.


The legendary rough and ready prospectors of old had a nose for diamonds. Today, our Exploration Team holds qualifications in geology, physics, geophysics, engineering, chemistry and biochemistry. They're equipped with the latest analytical equipment, tools and tests and supported by state of the art laboratories. And of course they still have that nose for diamonds.

Kimberlite core samples from Northern Canada can hold vital clues - traces of indicator minerals or diamonds themselves, but only careful laboratory analysis will show whether the find will become a viable diamond mine.
An exploration team takes seismic readings in Angola. Finding diamonds hidden beneath the surface can take decades. No clue is too small - even traces of indicator minerals brought up by burrowing animals and termites.
We search for diamonds where nature has left them, in some of the most remote and inaccessible places on Earth. Our geologists work in a range of places across the planet, from the deserts of southern Africa to the frozen Arctic tundra.

Diamond Mining

Above ground, below ground, along the courses of ancient rivers, on coasts, under the sea and beneath frozen lakes, in four countries on two continents, we mine in partnership with our hosts. We work responsibly to ensure that when diamonds are found, they play a central role in the community’s efforts to create jobs, improve education and healthcare, and build infrastructure.

Off the Namibian coast we recover diamonds from the ocean floor using cutting-edge technology on vessels that are virtually floating mines. Namibia's marine resources are the richest in the world
At the world's richest diamond mine, Jwaneng, in Botswana, an effective sustainability approach means a diamond super-pit can co-exist with the local ecosystems. The 17,000 hectare Jwana Game Reserve is within the Jwaneng mining lease area.
Trucks with 250 ton payloads and tyres twice as tall as an average man carry diamond-rich kimberlite to be processed. We train a highly skilled workforce of men and women to run these big machines.

Diamond Sorting

Sorting is both a science and an art. With more than 12,000 different categories of diamonds, it takes a trained eye and years of experience - supported by advanced diamond imaging and our bespoke sorting technology - to determine each rough stone's value based on its cut, colour, clarity, and carat size.

At the world's largest and most advanced diamond sorting facility in Botswana, sorters examine selections of diamonds straight from the mine. Increasingly, highly skilled sorters in Botswana, Namibia and South Africa are handling their countries' precious resource
Every diamond is unique. Determining its shape or 'model' is a key part of the sorting process. That will often determine the final size and shape of the polished jewel a particular stone is destined to become
Sorted diamonds are scrutinised by clients, known as Sightholders, who are supplied with the specific rough diamonds that our sorters have set aside for their diamond cutting and jewellery making requirements.

Diamond Cutting &Polishing

Cutting and polishing a diamond brings it to life. In the hands of master craftsmen, known as diamantaires, rough diamonds are transformed into beautiful gems sparkling with brilliance, fire and light. The art, passed down through generations in Antwerp, Tel Aviv, New York and India is also moving closer to the sources of diamonds.

An experienced diamond cutter carefully studies a rough diamond before marking it for cutting. Locked inside every diamond is its own best shape for optimal sparkle and life.
Only diamonds can cut and polish diamonds. The same method, grinding on a scaif, has been used for centuries. The hand-operated wheel, coated with diamond dust and olive oil, was invented in 1456.
Brilliant round, princess, emerald, pear, heart, marquise, oval or baguette - whatever shape the cutter chooses, once cutting begins there is no room for error. A perfectly proportioned brilliant cut diamond has 58 individual facets
