This extraordinary Mid Century engagement ring centers on a commanding 5.02 carat old mine cut diamond, radiating soft, romantic brilliance with its distinctive hand-cut facets and open culet. The diamond’s presence is both bold and graceful, enhanced by sleek baguette cut side stones that introduce a refined, linear contrast. Set in polished platinum, the design reflects the clean sophistication of the 1950s while allowing the center stone to take full focus. Impressive in scale and rich in character, this ring is a timeless statement of elegance and enduring craftsmanship.

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!
