# PVD TREATMENT
PVD (physical vapour deposition) is a process of coating objects with a film of metal, borrowed by watchmakers from high-tech industry. It can be used to produce a wide range of tints (yellow gold, rose gold, black steel, gunmetal steel), and is extremely resistant to wear and oxidation. We use this process for our whole range of leather and steel products.
This involves electroplating with rhodium, a very rare and precious silver-white metal which protects the underlying metals from oxidation.
Ruthenium is an extremely precious, anthracite-black coloured metal. It protects silver against oxidation
Vermeil is a precious metal obtained by electroplating 18 carat yellow or rose gold. This process has been used since antiquity in many different civilisations. Vermeil jewellery can be recognised by the guarantee of its “V” hallmark.
