The Overtone Pearl Strand Necklace is a defining piece of the OVERTONE collection. Featuring 28 meticulously hand-selected South Sea pearls, each wrapped in 18 karat yellow gold and natural diamonds. The design reimagines the classic pearl necklace through an organic, contemporary lens, utilising a unique and innovative stranding technique for an exceptional drape.
204 round white diamonds totalling 1.54 carats set along the gold fluid line, dancing along the form of the necklace, amplify the pearl's natural lustre. Designed to sit high around the neck with a 15 inch circumference and finished with our signature bayonet clasp, this piece can be made bespoke to custom-fit.

Pearls are organic and soft. They require care to keep them looking their best.
Avoid contact with any liquids, including water and chemicals. If pearls become wet, gently wipe away moisture with a soft, dry cloth as soon as possible.
Store pearls away from other jewellery and rough surfaces to avoid scratches and marks, and keep out of direct sunlight.
