Hailey B Oval Lab Diamond Solitaire Ring

One of our most-loved designs from the first and second bespoke lab diamond windows — the Oval Diamond Solitaire. A brilliant oval-cut lab-grown diamond sits at the centre, cradled by a hidden halo that wraps softly around the prongs to catch the light from the side, while staying invisible from above. Paired with a plain solid gold band — a clean, classic silhouette that lets the stone speak first.
We use Colour D, VS1 lab diamonds as default.
