Art Deco 18ct Gold & Platinum, Onyx & Diamond Rectangular Ring

272H
Rare Find
Written by Olly Gerrish

A good Art Deco onyx and diamond ring. It is all about the style and is very well made with a circular cut diamond and rectangular onyx centre within a rose cut diamond surround. It also has diamond shoulders. The decoration is the “millegrain” technique. This 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. Platinum is a hard metal so this process was particularly suited to it. It would make a great engagement ring.

Ollys Pick

I always love this style of ring and this is a great example!
