Dianoir® G4 is skin friendly

With dianoir® G4 the world of luxury and fashion comes into a new aesthetic and technical dimension.
Many fashion accessories (earrings, rings, bracelets, etc.) are made with materials containing nickel. The standard legislation EN 1811: 2011 + A1: 2015 has set nickel release limits for objects in contact with the skin.

Argor-Aljba has developed the Dianoir® G4 DLC coating which, in addition to embellishing the objects coated with its deep black, is able to reduce the release of nickel ions by 80%, helping to make the objects themselves hypoallergenic.
