The Piece in Detail
Few marbles are as unmistakable as Nero Portoro: deep black with golden-yellow veins, quarried on the Ligurian coast and laid in palaces for centuries. As an iPhone case it becomes a piece of jewellery. The stone is cut wafer-thin and polished to a high gloss – cool and smooth under the fingers – and sits on a lightweight carrier layer, surrounded by a Bayer TPU frame that absorbs shocks and protects the display. Alcantara lines the inside.
Around 40 grams light, charges wirelessly, MagSafe as an optional add-on. Available for iPhone 18 Pro and 18 Pro Max, the iPhone 17 family including Air, every iPhone 16 and back to iPhone 13. Marble from Antolini, Verona – finished in our workshop in Mönchengladbach.

Stone & Origin
Protection & Fit
Real stone on the back, framed by a shock-absorbing bumper. 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
