About This Piece

This Art Deco ring embodies all the key characteristics of the period with geometric shapes and striking contrast. The step style shoulders, set with little diamond sparkles, frame the central double square setting elgantly. At the centre is a transitional brilliant cut, which perfectly shows how this iconic diamond cut evolved from the chunky old cuts of earlier eras to the precise modern brilliant cut that we know today. The pierced gallery allows light to flood in under the setting for maximum sparkle, while the delicate cut outs, visible from the top of the piece, create contrast through shadow

 

Why You'll Love It...

This piece captures that striking but effortless beauty of the Art Deco period. It has just the right amount of presence on the finger with a subtle but definite sparkle. The round stone in a square setting is a classic Deco detail before square cuts were common and gives the ring a certain balance and softeness to the structure

I love both the Diamond Ruby ring I got and the Diamond earrings. Both are very high quality pieces and as described. They were very well packaged and the shipping was fast. I would love to make another purchase soon! My ring and earrings were very well pacakaged.

I cannot fault the ring the customer service and the packaging. The pictures did not do this piece of jewelry justice. It is stunning and I am so thrilled with it. Could not be happier at every step of the purchasing process. This is a ring that I will treasure.

Melissa Eskridge ~ July 2025

What a joy to be in Paris and find the perfect gift for a 40th wedding anniversary. I had my heart set on an opal solitaire, preferably vintage design, and found exactly that. The ring even fit, no sizing needed. Rebecca is a pleasure to work with, and I enjoyed the chance to meet her. I found the ring browsing online and would have ordered it from home (the USA) had we not been within a couple of miles of each other in Paris. Her knowledge of fine jewelry is evident, and she could not have been more thorough or courteous. I had my jeweler take a look when I got home, and he said it's an amazingly fine gem, no damage at all, rare in vintage opals because they're "softer" than most stones and require conscientious care. This one will get just that. Thanks Rebecca!
