If you're a budding geologist or rock hound looking to take your hobby to the next level, then good news abounds, as UK company Cover-Up has just unveiled a collection of real stone phone skins and laptop cases.
The items have been crafted from real slate before being hand-finished at the Cover-Up workshop in South Wales. A lightweight polycarbonate shell and raised bezel provides additional protection from drops and bumps, as does the rubberized edges.
If you're worried about extra weight, then fear not, as the skins are only 0.7mm thick and weigh less than 80g.
