A refined Mid Century platinum engagement ring, featuring an octagonal step cut diamond with carré and tapered baguette accents for a sleek, architectural sparkle.
Certificates:
This Mid Century diamond engagement ring is a beautifully refined piece from the 1950’s, crafted in platinum with a clean, architectural design. At the center rests an octagonal step cut diamond weighing 0.55 carat, graded H in color and VS in clarity. Its crisp shape and elegant step-cut faceting create a sophisticated focal point with a quiet, graceful sparkle.
Accenting the center stone are 4 carré and tapered baguette cut diamonds weighing approximately 0.25 carat total, H in color and VS-SI in clarity. These geometric side stones enhance the ring’s structured silhouette, adding balance, dimension, and a polished touch of brilliance. The combination of step cut, carré, and tapered baguette diamonds gives the ring a distinctly Mid Century elegance with timeless appeal.
Crafted in platinum and hallmarked with a purity mark, this ring has a cool, refined finish that beautifully complements the clean lines of the diamonds. Weighing 5.24 grams, it offers a graceful yet substantial feel on the hand. Classic, elegant, and full of vintage character, this engagement ring is a wonderful choice for someone who appreciates architectural design, refined craftsmanship, and understated diamond 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!
