Certificates:
A cushion shaped old mine cut diamond rides high in slender platinum claws, and a closer look beneath the stone reveals a hidden surprise: a delicate band of small round brilliant cut diamonds that sparkles whenever the ring catches the light from the side. Twelve diamonds in all, weighing approximately 0.10 carat in F color and VS clarity, sit under the center, which weighs 0.90 carat and is graded G in color with I1 clarity under GIA report number 2537676977. Its big, rounded facets give it an antique softness. The slim, polished band is yellow gold, with the white platinum setting keeping the stone looking bright, for a gentle two-tone effect. Crafted in 18k yellow gold and platinum and stamped with a purity mark, the ring weighs 4.18 grams, a solid and comfortable weight. Circa 2026, it suits someone who wants a classic solitaire with a little hidden sparkle.

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!
