The Gold Color Chart Daumet could produce with its innovative gold alloys

A gold that takes care.

Of the planet, of the skin, of time.

C.A.R.E. Gold™ is a platform, not a single product. Patented gold-tungsten alloys, applied by PVD, in certified 18K and 22K and in any shade between white and 24K. One process, whatever the collection asks for.

The promise

The fourth answer, made measurable.

Of the planet

Gold that reads as gold, for a fraction of the metal. No rhodium, and none of its price volatility. A markedly lower carbon footprint than rhodium plating, measured per ton processed.

Of the skin

Nickel-free, tested to EN 1811 across the whole platform. Compliant with EU REACH limits, aligned with US guidance on prolonged metal-skin contact.

Of time

Lab-certified for abrasion, humidity and colour-fastness. The finish lasts collections, not seasons.

The platform

Two certified karats.

C.A.R.E. Gold™ White

Yellow and rose plating exist. White did not. The colour that carries the highest retail premium, holding where rhodium wears and silver tarnishes.

C.A.R.E. Gold™ 22K

The saturation and warmth of high-karat gold, with a wear resistance conventional 22K plating does not reach.

C.A.R.E. Gold™ Bespoke.

Your own colour, anywhere between 18K white and 24K yellow. Formulated once, reproduced batch after batch - a hue no competitor can replicate, and a composition you own. This ring carries a dedicated 21K champagne, developed for a client sensitive to nickel and rhodium.

The process

PVD gold, atom by atom.

Physical Vapor Deposition - the process behind every C.A.R.E. Gold™ finish.

Vapour, not a bath

Gold becomes vapour, then settles atom by atom onto the surface. A lab-grade process, repeatable and measurable. Thickness, density and colour: specified, controlled, documented.

A patented alloy

Gold-tungsten composition. Patent family granted in the United States, China and the European Union.

Ten years in production

Refined over a decade of series production for the French houses of haute maroquinerie. Not a proof of concept.

GOLD HAS ALWAYS EXISTED. WHAT WE DO WITH IT HAS NOT.

C.A.R.E. Gold™ opens to a limited number of jewelry partners in 2026.
