A promise deserves to be held in something lasting.


This handmade 18ct gold engagement ring cradles a 1 carat oval lab-grown diamond in a platinum four-claw setting – a design chosen for its strength, brilliance, and timeless beauty.

The oval cut carries a sense of grace and continuity, symbolising an unbroken bond. The warmth of the gold band meets the cool resilience of platinum, echoing the balance of strength and tenderness in a relationship.

Every diamond is sourced directly from the cutter, giving you the assurance of full traceability and exceptional value. Each ring is crafted by hand in the UK, so no two are ever exactly the same – just as no two love stories are alike.

To honour your journey together, this ring comes with:

A free lifetime guarantee against any manufacturing fault

A complimentary annual check-up to keep the setting secure

An updated valuation on request, so your treasure is always protected

More than a ring, it’s a story of care, meaning, and lasting love, designed to be worn every day and cherished for a lifetime.
