Title, I wonder how many Rock Crystals have been wasted because people forgot that you need to be extra careful with them.
EDIT: Clarification, when you get Rock Crystal (item) from Rock Crystal (node) it should only count as Rock Crystal (required to build Charter Stone, Coronation Stone, and certain Mine Holes, or as gilding.) You then have to turn it into something that counts as stone for crafting/building. This way the Rock Crystal has all the functions it currently has, only the game doesn't **** you over when you fail to remember Rock Crystal is also a stone and it goes to claim pole of village idol.
The process could be as simple as right-clicking the Crystal and getting an option like "Break" or "Shatter" (preferably with an hourglass timer to cancel a miss-click) or a more involved craft, perhaps even involving a hammer and an anvil.
