A diamond is not stable. At room temperature and pressure the stable form of carbon is graphite, and every diamond is quietly on its way to becoming it, on a timescale of millions to billions of years. Most were made between 150 and 250 kilometres down, are between 1 and 3.5 billion years old, and reached the surface only because violent volcanic eruptions carried them up in kimberlite.
Even with modern tools, cutting and polishing a rough diamond destroys about 50% of its weight. Price jumps at round numbers, so cutters routinely accept worse proportions to keep a stone above one carat. The waste can be deliberate and enormous: the Koh-i-Noor was recut in the 18th century for English tastes, and almost 80 carats were lost.
The Cullinan came out of the ground in 1905 at 3,106 carats. Joseph Asscher spent four days cutting a groove 0.5 inches deep before he could cleave it in a single strike. A steel knife broke on the first attempt. Splitting and cutting the whole stone took eight months, with three people working 14 hours a day.
A diamond is worth a great deal for its weight, which makes it portable and comparatively easy to smuggle. Deep kimberlite mining needs capital and expertise; alluvial diamonds need only simple tools and control of the land, which is why armed groups favour them. In Sierra Leone, the Revolutionary United Front seized the mining areas and paid for its war with them.

A single diamond rests on volcanic rock, juxtaposing refined brilliance against raw, rough geology. The composition speaks directly to the exhibition's central tension: carbon transformed by extreme pressure into something precious.

A rough crystal rests against fabric texture. Unpolished and natural, it shows carbon and minerals in their unrefined state, before pressure transforms them into gems.

Light and dark converge in this surreal seascape. The image explores how pressure shapes landscapes. Ice and volcanic rock, both born from extreme forces, meet at the shore.

Raw crystal lies on white, exactly as nature formed it. Before cutting, before pressure is released into brilliance, here is the material in its honest state.

Multiple faceted gemstones catch light on a clean surface. This study of refraction and luminosity demonstrates how pressure reshapes carbon into forms that scatter and amplify light.
