Certificates:
This elegant vintage engagement ring centers around a 0.80 carat old mine cut diamond, certified by GIA under report number 7531677080. The diamond displays a desirable G color grade, offering a bright near-colorless appearance, paired with VS2 clarity, meaning only minor inclusions are present and not easily visible without magnification. The stone is set in a platinum mounting, a highly durable and premium precious metal known for its weight, strength, and naturally white luster that does not fade over time. Designed in an east-west orientation, the diamond is positioned horizontally across the finger, giving the piece a modern, fashion-forward twist while maintaining its antique charm. The ring originates from the circa 2000s vintage period and retains original hallmarks, including purity stamps and maker’s marks, confirming authenticity and craftsmanship. Weighing 6.83 grams, it has a substantial yet comfortable presence on the hand. The ring is currently a size 6 and can be resized to ensure a perfect fit.

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!
