Set of three raw rubies

Set of three well formed raw ruby crystals in their typical barrel shape. These three crystals are not transparent, but do carry light nicely. 
 
I have polished one of these crystals seperatly (not included in this set) and it came up lovely! So you can definitly polish these. 
 
These are second hand stones, purchase within a large collection of worldly Gems and Minerals. The origin of these stones can not be determined without proper testing. I do not believe these are Australian Stones.
