Your unique piece in detail
Deep black with golden-yellow veins: Nero Portoro turns your iPhone into a piece of jewellery. Polished to a high gloss, the wafer-thin stone feels cool and smooth under your fingers, set in a frame that absorbs shocks and protects the display.
Every piece is one of a kind. The photos show an example – the veining on your veneer will run differently.
