A technique developed in the late 19th century as a textural effect to metal work on the edges or bezels of jewellery. That technique is referred to as millegrain (or mille grain or even milegrain). From the French word mille for a thousand, and from grain as the same meaning in English, it refers to what appears to be thousands of tiny beads upon a metal precipice or edge. Fine platinum settings and in particular diamond rings, engagement rings and gemstone set rings, often employ this device. It is defined as a technique where a knurling or a millegrain tool is impressed into a metal edge leaving furrows and also beads or tiny ridges of metal.
