Under the loupe
Ten times closer, still flawless.
Move across each plate to look through a jeweller's 10× loupe — the same magnification our gemmologists use to grade every stone before it is set.
The pear, 58 facets
Cut over nine weeks from a 41-carat rough to keep a perfectly symmetrical bow-tie-free face.
Invisible claws
Each claw is filed to 0.4 mm and polished by hand so the metal disappears and only light remains.

01 — Design
Painted in gouache
Every piece begins life as a white gouache drawing on black card, rendered at true scale.
-
02 — Setting
Set by a single hand
One master setter, 1,400 hours, 752 claws raised and closed under the microscope.
-
03 — Light
Tuned to the light
The finished rivière is tested under candle, daylight and spotlight before it leaves the house.
Worn
“It does not sit on the skin. It hovers, like the last light before night.”
— Hélène Marchetti, Creative Director
