Director's Notes

The round old cut, sometimes referred to as the old European cut, originated in the late 19th century as a result of two major events that changed the course of stone cutting forever - the invention of the bruting machine, and the discovery of diamond deposits in South Africa. Characterised by its round outline, small table and high crown, it evolved from the cushion old mine cut which had been popular since the 18th century.
