The company Daumet offers a bespoke gold PVD coating service on a wide range of materials, including leather, wood, silk, textiles, and carbon fibre, to personalise luxury products. Specialised in white gold, the company developed different processes to coat several matters with gold from 24 to 18 karats. They use dry processes rather than working with liquid baths. In addition, the processes substitute two critical raw materials, palladium and rhodium, by a much more abundant element in the Earth: tungsten. Tungsten alloys are harder than palladium gold alloys.

The gold alloys are developed to fit the colour, the rendering and the wear resistance of the project.
