Diamonds surface in Golconda. For nearly two thousand years, India is the world's only source. Stones are worn close to their natural form.

Stone Sourcing & Development
A short history of chasing light.
We work two ways. Some stones are our own cuts: mapped in-house, hand-cut by our lapidarist partners. Others we source: spectacular cuts, antiques, stones we find and can't leave behind. Everything lab-origin is custom cut. Every stone we touch descends from this lineage:
European cutters polish the diamond's natural faces and stop there. The stone keeps the shape it grew in.
Rough octahedral diamonds in an eleventh- to thirteenth-century ring from Pakistan or Afghanistan. Benjamin Zucker Family Collection.
Someone slices the top off the octahedron. The first flat facet. Light gets a window.
Les Enluminures table-cut diamond ring, c. 1600.
Antwerp. A dome of triangular facets over a flat base, like a rosebud. Made for candlelight. It glows instead of flashing.
Hand-cut, one of one, every time. High crown, small table, open culet. Big lazy flashes of fire. No two alike.
Tiara, London, 1840โ42. Victoria and Albert Museum.
A young engineer publishes the mathematics of brilliance. Fifty-eight facets arranged for maximum light return. The modern brilliant is born.
