an un-cut emerald that cant be chiseled no matter what you try to do, only responds appropriately to action input words. 
does not have words to say only menu actions and consequences for those actions you choose to do.
your only options are to right click on me and see my menu of options which are as follows:
use-selects the emerald to be used on another thing.
drop- drops the emerald on the floor.
examine- inspects it.
cancel-cancels the menu. right click on me again to pull it back up.
