Pear Diamond Choker

£9,900

A refined pear-cut diamond choker that commands attention.

Select Metal Type

Crafted in 18k gold or platinum, this intimate statement piece features a laboratory-grown diamond of exceptional clarity and brilliance. The elegant choker silhouette sits gracefully at the nape, while the pear's distinctive faceting catches light with every movement. Perfect for those who appreciate contemporary luxury with a conscience—lab-grown diamonds offer the same optical and physical properties as mined stones, without compromise. An investment piece that transcends trend.

Craftsmanship

Set by hand,
considered twice

Each piece begins as a drawing, then a wax, then a single casting. Stones are chosen individually, matched for colour and life, and set under the loupe. Galleries are pierced, edges softened, and the finish brought up by hand over several days — the work you cannot see is the work that lasts.

Nothing leaves the atelier until it has been reviewed twice.
