This is the series of four 'On The Rocks' glasses available from UncommonGoods ($48 for the set). Each 13oz glass is wrapped with a photorealistic closeup of a different kind of stone taken by photographer Barry Rosenthal. If dropped, they will still shatter though, because they're glass and not rock. Alternatively, carve your own cup out of actual rock. That's what I'm going to do. And if that cup happens to be carved from the penis of Michelangelo's David, well, that's the plan.
Thanks to chichi, who is only allowed to drink out of sippy cups because spills.
