Lab grown diamond necklaces and tennis necklaces

A necklace is the piece a woman sees most often — in the mirror, in a window, in a photograph years later. So we build ours around the line of the collarbone: chains drawn to lie flat, pendants weighted to sit centred, tennis necklaces graded stone by stone so the light travels without interruption. Each lab grown diamond is IGI certified and hand-set in 18ct gold or platinum in our London atelier.

You will find solitaire pendants for everyday wear, halo and heart designs for a first gift, riviere and tennis necklaces for evening, and layered lengths made to be worn together. Lengths can be shortened or extended, clasps changed, and stones matched across a set of earrings and a bracelet. Delivery is complimentary in the UK and insured worldwide, and every piece is accompanied by its IGI certificate.
