Six carats — set to order by the House for the hand, the ear or the neck they will live on.












The round brilliant is cut for one purpose above all others — the return of light — and at six carats that return is unmistakable across a room. The House holds 33 pieces at this weight, each certified by GIA, IGI or HRD and hand-selected for cut precision.
Colour and clarity move the figure sharply at this weight, more than the round brilliant's cut itself, which is already the most standardised of any shape the House works in. Every piece carries one transparent price with the certificate shown first.
For the light return, and for the certainty of a well-understood cut. Fifty-eight facets is the classic count, engineered over a century to maximise fire and scintillation — at six carats, that engineering is on full display.
