Edwardian 18ct Gold & Platinum, Large Sapphire & Diamond Cluster Ring

312H
Written by Olly Gerrish

An impressive 18ct gold & platinum ring that was made circa 1920. The sapphire is a lovely deep blue, most likely of Burmese origin. The diamonds are at least 20 points each and are very well matched bright white stones. The settings are millegrain, a technique that was developed in the late 19th century. It is from the French word “mille” for a thousand, and from “grain” as the same meaning in English. It refers to what appears to be hundreds of tiny beads upon a metal edge. Fine platinum settings and in particular gemstone rings often employ this device. It would make a wonderful engagement or dress ring.
