DAUMET AS A GAME-CHANGER

Today launching the whitest gold in the world, DAUMET is daring enough to help you combine rarity, desirability and emotion.

 

For more than 1000 years, two precious metals have been used to preserve whiteness and shine of white gold: palladium and rhodium. But the thin rhodium layer disappears over time, revealing the greyish metal.

Whiteness or eternity…this is a historical dilemma for jewelers and watchmakers !

 

This innovative material is today controlled for coating applications and DAUMET has planned to continue its research in order to offer this white gold for casting and/or additive manufacturing.

A patented innovation

As part of research work in microelectronics conducted with Albert Fert, 2007 Nobel Prize in Physics, a new material composed of gold and tungsten has been patented by CNRS. In its 750/000 composition (3/4 gold and 1/4 tungsten), this innovative alloy proved to be the whitest gold in the world!

This innovative material is today obtained as PVD coating (Physical Vapor Deposition).

The first white gold coated jewel

Designed for bridge and fine jewelry

With a CIE Lab color never seen before, the DAUMET white gold is also non-allergenic, durable so it’s a guarantee of comfort and safety for your customers.

In fine jewelry, its unlimited coating thickness improves the lifespan of jewels and allows to reduce the palladium concentration in your massive white gold pieces.

In bridge jewelry, this new gold alloy gives you the opportunity to launch a new product: the first white gold coated jewel, as an alternative to silver and rhodium plated jewels.
