Cathedral Three Stone Diamond Engagement Ring
Cathedral Three Stone Diamond Engagement Ring
🚚 Next-day UK delivery available on all in-stock items.
This exquisite platinum three stone cathedral diamond trilogy ring is a signature masterpiece by designer Christine Sadler, blending structural grace with deeply romantic symbolism. Representing your shared journey across the past, the present, and the future, this architectural design captures and reflects light with extraordinary brilliance.
The central round brilliant-cut diamond is elegantly framed by two matching accent diamonds, creating a continuous, balanced river of exceptional fire across the finger. Inspired by the soaring arches of historic architecture, the platinum shoulders gracefully sweep upward into a vaulted, six-claw cathedral setting that safely elevates and protects the stones.
Designed as a snuggle-fit silhouette, the high-vaulted setting allows a traditional straight wedding band to sit completely flush next to it without requiring a custom contour. This original 0.50ct signature ring is handmade to order and available to view in our Ayr studio.
Would you like to customize this trilogy setting with alternative diamond weights, lab-grown diamonds, or alternative natural gemstones? Simply WhatsApp our studio team directly on 07749890107 to request a bespoke quote or to plan your custom layout.
