Art Deco Platinum & Diamond Brooch

269H
Rare Find
Written by Olly Gerrish

A smart Art Deco platinum and diamond brooch of openwork design. The decoration around the diamonds 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. The principal diamond is 35 points.

Ollys Pick

I love the really fine Art Deco brooches such as this one.
