UK-based accessories brand Cover-Up has rolled out a range of cases and skins for Apple’s MacBook and iPhone 7… made of real stone.

Available for the MacBook Pro and MacBook Air, as well as both the iPhone 6 and 7, the cases are made from real slate stone, which is hand-finished at Cover-Up’s manufacturing facility in South Wales. A lightweight polycarbonate shell and raised bezel provides additional protection from drops and bumps, as does the rubberized edges.

Also, the stone cases don’t add much weight, if you’re worried. The skins are only 0.7mm thick and weigh less than 80g.

Check out the collection at Cover-Up’s online store.
