Daumet - A new generation of gold alloys for clean and sustainable aesthetic applications (luxury and jewelry).

Daumet substitutes pure gold by more resistant gold-based materials while conserving gold properties decreasing the carbon footprint of its using.

To keep rare resources for the future generations and decrease the carbon footprint of gold applications, Daumet proposes to use gold differently thanks to an innovative and patented gold alloy presenting large similarities with pure gold. Daumet mix gold with tungsten, the hardest metal and the only one presenting the same density than gold. This ultimate gold alloy has properties common to pure gold. However, it is more resistant (mechanical, temperature...), cheaper and more sustainable because tungsten is more abundant in the Earth.

Key features

  • 20% less CO2 emitted in the atmosphere
  • 30% less water pollution


  • Pure gold (45k€/kg) is substituted by tungsten which costs around 5€/kg
