Certificates:
Circa 1930, this ring embodies everything collectors love about the Art Deco period — clean geometric lines, a love of platinum, and a confident central diamond. That diamond, an old mine brilliant cut weighing 0.93 carat, is GIA certified (#6542934893) at H color and VS1 clarity, its deep, warm sparkle a hallmark of the antique cutting style still favored by connoisseurs today.
Radiating outward, thirty single and marquise cut diamonds totaling approximately 0.40 carat in G-H color and VS clarity trace the ring's architectural silhouette, their crisp lines and symmetry pure Art Deco design language. Crafted entirely in platinum and bearing its original hallmark, the ring showcases the metal's strength and cool luster — a material choice that came to define fine jewelry of the Jazz Age.
At 3.43 grams and sized 6.25, this is an exceptional choice for a couple seeking an engagement ring with real period authenticity — a certified diamond, a documented era, and a design that has never gone out of style.

Beyond obsessed

I'll just start by saying that every piece of vintage jewelry in this shop is more beautiful than any other I saw in all of LA. Not only do I absolutely adore my ring, I had an amazing experience here as well. Basically the dream situation for a newly engaged gal!
