A refined addition to our Convex Collection, the Oval Lab Diamond Ovolo Ring elevates soft curves and tactility. This design features an oval profile ovolo band paired with a shaped bezel setting that fully encloses the diamond. Highly protective for everyday wear, the closed-back setting allows for easy cleaning and ensures the stone maintains its brilliance with minimal upkeep.

This ring is currently a size L1/2 and can be adjusted free of charge to any size between J1/2 and N1/2. Simply include your desired size at checkout. Resizing will be completed within the standard 1–2 week delivery window.

We set out to celebrate curves, intersections, and thoughtful engineering, carefully considering how the setting integrates with the band. The result is a design that keeps the profile of a large diamond as low as possible while still allowing another band to sit comfortably alongside it. Bold, well-proportioned, and fully protected, this is a diamond ring you can wear every day without a second thought.

Made from recycled 14ct gold sourced through a closed-loop refinement process, no newly mined material is added. This ring features a 1.32ct IGI certified lab-grown diamond of F colour and VS1 clarity. We use lab-grown diamonds sourced from responsible, fully traceable, carbon-neutral suppliers who uphold fair-labour and ethical business practices.

The mirror-polish finish enhances the ring’s sweeping reflections and sculptural form. Though one of the simpler designs in the collection, it can be stacked with our more detailed bands to create a ribbon of colour and texture down the finger, or paired with a minimal band for an understated modern look.

Please allow 1-2 weeks delivery time.
