Manged to have the stones tested at the jeweler. 
 
Hilt = Quartz 
Eyes & forehead stone = Rubies (fairly good quality albeit not the best) 
small red stones = Rubies (low quality; tested just a couple of them as they are carbochon and difficult to test but did a visual exam on the rest) 
orange stones = probably Aghate but unsure as they are too small 
green stones = glass  
 
While they couldn't be 100% sure they said the mountings appear to be untampered so probably all stones are the originial ones.
