In its natural state, gold is a soft yellow metal. To harden it, it is mixed with other metals and, depending on the mixture (metals used and their proportions), the three main known colours are obtained: yellow, pink and white.

For 1000 years, only 2 processes have been used to obtain white gold:

  • the first, a mixture of fine gold and nickel, is now forbidden in many regions, including Europe, because of its allergenic nature;
  • the second consists of combining pure gold with palladium, a metal that is even more expensive and rarer than gold.

In both cases, white gold jewellery is often covered with a thin layer of an even whiter and brighter metal: rhodium. But this thin layer disappears over time, revealing the greyish metal.

Whiteness or eternity…the historical dilemma of the jewelers/watchmakers..

DAUMET offers a concrete and eco-responsible alternative with its new 18-carat white gold…

Periodic table


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. In its 750/000 composition (3/4 gold and 1/4 tungsten), this innovative alloy proved to be the whitest gold in the world!

Thanks to its whiteness and wear-resistance properties, DAUMET now produces the world’s first white gold-coated jewelry. The opportunity for jewellers to offer for the first time their collections plated in the three colours of gold, whereas white was previously impossible for them.

DAUMET is continuing its R&D work in order to offer this white gold as soon as possible in its massive state and thus completely resolve the dilemma between whiteness and eternity. A first step towards this metallurgical Holy Grail…


Exclusive as much for its whiteness, brilliance, durability as for its non-allergenic character, the new white gold designed by DAUMET is revolutionising the world of top-of-the-range costume jewellery and luxury accessories. The white colour obtained until now with silver or rhodium can now be declined with gold, more precious and more eco-responsible.

For women’s or men’s jewellery, couture or designer pieces, from gilding to plating, DAUMET adapts its process to the aesthetic and wear-resistance requirements of its partners and customers.

Palladium and rhodium are two of the four rarest metals on earth. Their resources are dwindling as they are increasingly used in the catalytic converters of cars. The more we want to breathe in cities, the more we consume these two metals.

By substituting these two rare metals with tungsten, which is much more abundant in the Earth and therefore has a much lower impact on the environment, DAUMET actively participates in reducing the carbon footprint of jewellery and is therefore supported in its approach by the European Union.
