What would happen if I put a rough aquamarine in

Aquamarine is a form of beryl, a ceramic (Be3Al2Si6O18) of beryllium metal. Like most ceramics, it's not very electrically conductive, and so won't have large currents induced in it by microwaves, and most likely won't get any hotter than any other ceramic, such as a coffee cup, would.
