A seam beneath Sri Lanka.

Vein graphite forms only where geology grants permission. A fluid carbon-rich melt rises through fractures in the earth, cools slowly under pressure, and crystallises into structures of near-perfect order. It cannot be farmed. It cannot be grown. It is found, or it is not.

Sri Lanka holds, by an accident of geology, the largest known concentration of high-purity vein graphite in the world. The Ragedara seam in Melsiripura has been worked since the late nineteenth century. Until the end of the Second World War, this mine produced the highest-grade graphite traded on global markets - material that found its way into everything from arc-lamp electrodes to the first generation of nuclear reactors.

For decades after, the seam was under-exploited. Synthetic graphite, cheaper to scale and easier to standardise, captured industry attention. But synthetic carbon will never match the crystallinity that a hundred million years of geological pressure produces naturally. As graphene research intensified through the 2000s, the limitations of synthetic feedstock became clear: defects, contamination, layer disorder.

Graphenera was formed in 2012 to bring this material back to the world on its own terms. The mine was reopened with modern stewardship practices. Partnerships were established with German processing laboratories. The specifications you find on this site - the conductivity figures, the layer counts, the surface areas - are what happens when you start with material this pure and treat it with care.

At present operating capacity, more than two hundred years of working reserves remain in the seam. We do not intend to exhaust them. We intend to leave a working mine for whoever inherits this work after us.
