The 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.

Stone & Origin
Protection & Fit
Real stone on the back, set in the Black Frosted Case: a matte, frosted black frame made of Bayer TPU that absorbs shocks and sits slightly above the display. Camera, buttons and ports stay fully accessible, and wireless charging works right through the case.
Care
Stone is easy to look after: a drop of Stone Cleaner on a soft cloth and the surface is clean again. Polished stone regains its depth with Marble Polish, while slate stays naturally matte. Care guide
