WATERPROOF TECHNOLOGY
ONE jewellery is made from 316L surgical steel, a high-quality hypoallergenic material, and finished with an 18K gold PVD coating.
In short, this technology ensures excellent resistance to wear and helps preserve the colour over time.
And we’ve officially taken things one step further with an EXTRA ONE LAYER: an additional protective layer made with alumina. This means the pieces are protected against fresh water, salt water, chlorine and sweat.
