$ 11,500
A timeless Mid Century platinum engagement ring featuring a GIA-certified 1.51 carat old mine brilliant cut diamond flanked by elegant tapered baguettes.
Certificates:
This elegant Mid Century engagement ring is a beautifully balanced design from the 1950’s, centered by a GIA-certified old mine brilliant cut diamond weighing 1.51 carats. Graded I color and SI2 clarity, the center stone offers broad, romantic faceting and a luminous presence filled with vintage character.
Flanking the center diamond are 2 tapered baguette cut diamonds weighing approximately 0.25 carat in total, graded G-H color and VS clarity. Their crisp step-cut facets create a refined contrast against the softer brilliance of the center stone, giving the ring graceful symmetry and a classic three-stone silhouette.
Crafted in platinum and hallmarked with purity marks, the setting provides a cool, polished backdrop that enhances the beauty of each diamond. Timeless, sophisticated, and full of Mid Century charm, this ring is a wonderful choice for someone seeking a certified old cut diamond engagement ring with elegant proportions and enduring 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!
