The style of Art Deco originated from Paris and was developed between the 1920s to 1930s. Art Deco engagement rings were usually colourful, geometric, decorative, and architectural. Platinum was the popular choice of metal, and the rings usually held a centre gem surrounded symmetrically with more gems. Diamond was the most dominant gem used in Art Deco jewellery. However, many colourful gems such as sapphires, rubies, and emeralds were also commonly used. The unique designs and dazzling gems of art deco engagement rings are so breathtaking to look at. Here are a number of beautiful antique art deco engagement rings that I found on Etsy.

Nice post. Big big fan of Art Deco.
Thanks! It’s hard not to like art deco :)
My engagement ring is an oval sapphire surrounded by a ring of tiny diamonds which we found in our jeweller’s collection of vintage engagement rings australia. I had a plain white gold band custom fit to it when we were married. Eveyrone who sees it says “wow that’s unique”
