If diamonds are very good thermal conductors, transparent, but the cut of the diamond concentrates light (and its energy?), would a diamond laying in the sun get hot - and if so (or not) would an infrared camera be a decent way to find a lost diamond laying in the grass? Simply put, would a 2 carat diamond create a "hot" or "cold" spot in the display of an FLIR camera?
FYI - I probably won't understand the reasoning behind why, so don't feel obligated to write a page and a half of explanation why - a yes or no with a brief description would be cool.
