Lab-grown diamond necklaces, made in London

Our diamonds are grown above ground in a matter of weeks — atomically identical to mined stones, certified by the same laboratories, at a fraction of the footprint. The only difference is the story. Yours begins here. Every piece in this collection is set by hand in our London atelier, in 18k gold or platinum, and configured to you — carat, quality preset and metal — on the piece's own page.

Each finished piece is independently graded by IGI or GIA and hallmarked at the London Assay Office — the same marks of assurance carried by fine jewellery for over seven centuries. Yours for life: resizing, re-polishing and care, on the house.
