Certificates:
This charming Mid Century diamond engagement ring from the 1950s is a beautiful piece centered by a GIA-certified 1.00 carat old mine cut diamond. Graded L in color and I2 in clarity, the center stone offers the warm, romantic character that makes antique cut diamonds so beloved. Its softly shaped facets and old mine cut personality give the ring a distinctive glow, creating a look that feels soulful, timeless, and full of vintage appeal.
Flanking the center diamond are 2 tapered baguette cut diamonds weighing approximately 0.10 carat total. Graded G-H in color and VS in clarity, these side stones add a clean, refined touch of brilliance while creating a graceful three-stone silhouette. Their sleek geometry beautifully complements the antique charm of the old mine cut center, giving the ring balance, elegance, and a subtle architectural feel.
Crafted in platinum and hallmarked with purity marks, this ring captures the understated sophistication of Mid Century design. Its combination of a GIA-certified old mine cut diamond, crisp baguette accents, and classic platinum setting makes it a meaningful and romantic engagement ring for someone who appreciates vintage character, hand-cut diamond charm, and a piece with enduring beauty.

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!
