S.I.L.O. Spa, thanks to the prototypes developed and the new technology used, has created a range of innovative products including jewellery and chains. The new products feature an iridescent finish which changes depending on the light and position, and better resistance to wear, thanks to the new PVD treatment developed by Romana Film Sottili.

The new products were finally enhanced with environmentally friendly galvanic deposits - developed by Valmet and UNIFI - that are distinguished by the absence of toxic heavy metals.
