Mar 5 2013 Bedazzled tech accessories are nothing new under the sun of flairful tech accessories, but iPhone cases made of genuine stone? That's a hard act to follow. Case-Mate has just introduced its new Gemstones Collection, crafted from some of the most exquisite mineral stones. The petite collection includes three styles: white howlite with rose-gold inflections, turquoise with warm gold striations, and jet gemstone with pyrite inclusions. Each is beautifully contrasted with a complementary brushed aluminum frame. Ringing up at $150 each, we'll consider these investment jewelry.
