Oval Lab Diamond Hidden Halo Cathedral Engagement Ring
£4,449
Made to order — approx. 3–4 weeks
An elongated oval lab-grown diamond sits elevated within a sculpted cathedral setting, creating a naturally lengthening silhouette across the finger. The tapered shoulders draw the eye toward the centre stone, allowing its proportions to remain the dominant visual element of the design.
Beneath the setting, a hidden halo introduces a discreet circle of additional brilliance that becomes visible from the side profile. This detail adds depth and light without interrupting the clean, uninterrupted view of the oval diamond from above.
Crafted in solid British hallmarked platinum and finished to a high polish, the ring combines architectural structure with careful hand finishing. The cathedral setting lifts the centre diamond to allow light to travel beneath the stone while maintaining a secure and balanced profile.
Designed for proposals and long-term wear, the ring pairs naturally with wedding bands and eternity rings while retaining a refined presence when worn alone.
