This exceptional contemporary collet ring is a refined homage to antique diamond craftsmanship, beautifully blending historic old mine cut diamonds with modern design sensibility. At its center are three individually GIA-certified old mine cut diamonds totaling an impressive 3.06 carats. Each stone displays the distinctive charm of early diamond cutting, with softly squared outlines, broad facets, and a romantic, candlelit brilliance that feels warm and soulful.
Graded W–X in color with VS2 clarity, the diamonds possess a rare and desirable character, offering depth and individuality rather than uniform perfection. Their harmonious pairing creates a balanced, elegant composition that draws the eye across the finger with graceful movement and symmetry. The platinum collet settings delicately frame each diamond, enhancing their presence while allowing light to pass freely through the stones.
The rich 18k yellow gold band adds warmth and contrast, elevating the antique diamonds with a luxurious glow and grounding the design in timeless sophistication. Crafted in 2025, the ring is a thoughtful reinterpretation of classic collet-set jewelry, honoring historical beauty while offering contemporary refinement. Substantial yet elegant, it feels both luxurious and wearable, designed to be cherished for generations.
Distinctive, romantic, and impeccably crafted, this ring is ideal for collectors and connoisseurs who appreciate certified antique diamonds, nuanced color, and jewelry that bridges past and present with effortless elegance.

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!
