Quick Tips
- Measure at the end of the day, when fingers are largest.
- Snug, not tight — the ring should pass your knuckle with slight resistance.
- Wider bands (4mm+) fit tighter — consider sizing up half a size.
- Between two sizes? Always size up.

Our Vintage Bezel Solitaire Lab Grown Diamond Engagement Ring is a masterpiece of Art Deco-inspired craftsmanship, where a brilliant 0.50ctw round lab grown diamond is cradled in a full bezel setting at the heart of an ornate circular engraved metal frame — a stunning medallion-style design with no competing stones, letting the lab grown diamond speak for itself.
It can be paired with Style R-DOC-105 to make it a bridal set.
The engraved circular surround features delicate segmented geometric patterns inspired by vintage Art Deco design, while the reverse reveals an intricate filigree and scroll openwork gallery that showcases exceptional metalwork from every angle. Grooved ridge details at the shoulders where the plain polished shank meets the setting add a refined architectural finish. A ring for those who value artistry and individuality over convention — timeless, distinctive, and completely unforgettable.
Available in 10K/14K/18K White, Yellow, or Rose Gold and Platinum.
