Crafted in 18ct white gold, our Sierra Ring is an extraordinary piece of jewellery that combines classic simplicity with opulent beauty. 

The centerpiece is a radiant 3ct yellow cushion cut lab-grown diamond, known for its vibrant color and captivating brilliance. This exceptional yellow diamond is the star of the show, and is surrounded by two exquisite heart-shaped diamonds, adding a touch of romance and perfectly complementing the vibrant yellow cushion cut. The diamonds are set on a sleek, plain gold shank, enhancing the overall elegance of the design.

The Sierra ring is set with a total carat weight of 3.80ct of dazzling lab grown diamonds, which are hand-selected and have a colour and clarity of F-G VS and come with IGI certificate.

Other grades of lab grown diamonds available on request.
