If the
cute and quirky illustrations from Rifle Paper and Cartolina don't fit the bill - what about these slightly more glam photos of minerals and rocks blown up to spectacular effect? I'm especially fond of the
white marble case which would look so chic wrapped around a white iphone.
Pink agate and sparkling amethyst designs are featured in
DS Brennan's Etsy store. If the geodes and gemstones aren't your thing, they also offer a range of other natural photo subjects.
Or something from
Weston Earth Images who are widely regarded for their photographic processes transforming natural materials into printed designs for products like iphone cases and silk scarves.
