Series title
De la recherche fondamentale à la deeptechSpinD Gold is an innovative combination of gold and tungsten. This novel material was obtained in connection with research in spintronics (a field seeking to exploit magnetism in electronics), led by Cyrile Deranlot and Albert Fert, winner of the 2007 Nobel Prize in Physics, at the Laboratoire mixte de physique CNRS/Thales. Used by the start-up #DAUMET, this new white gold is the whitest gold alloy ever obtained. Its brilliance and colour are first-rate in comparison to any other white gold on the market, and its composition based on tungsten makes it an environmentally friendly material. It is intended for the luxury goods and jewellery industries.

Daumet, the whitest gold in the world.
A new, whiter gold- brighter than before. Less expensive
and more environmentally friendly

CEO DAUMET
Cyrile Deranlot,
CNRS Founder in 2016 of the start-up
Daumet Paris.
Interview :
The name Daumet comes from daurare (old french for
gilding) and meta (change in greek). Our skill is to gild
in a different way .
Subtitles over image:
A gold and tungsten alloy, obtained from the successive
layering of gold.
Interview :
The very first time I removed this alloy from the machine ,
I was surprised by its colour and brightness. It was from
then studying the chemical and physical properties of gold
alloys that I realised we had just made the whitest gold in
the world.
Subtitle over image:
This new denser white gold, brighter and more ecologic
interests
⁃ the luxury goods industry
⁃ jewellers and watchmakers
Interview :
We combine an ancient know-how with modern
techniques, whilst respecting future generations.
Our objective is to become on of the leading makers of
precious metals
