Ask a question

Here’s a pleasing Art Deco emerald and diamond halo ring. It’s typical of the interwar years. 

Finely handmade in platinum, it sits low on the finger. This is always a plus for emeralds. 

Being more brittle than diamonds, sapphires and rubies, these glowing green gems can chip and must be worn with care. (It’s for this reason I don’t generally recommend emerald rings to the couples who come into my shop seeking an antique or vintage engagement ring.)

The cut of the main stone is a true emerald cut: an octagon. Often their angles are not so pronounced, resulting in a more rectangular shape with cut-off corners. 

The millegrain setting adds a refined finish to this French hallmarked beauty.
