Hopefully this hasn''t been covered recently in another post, but does anyone know of a good reference site for coloured stone values?
I am looking at acquiring a number of different stones, tourmalines, spinels and tanzanite (among others), but want to make sure I am not paying too much for each stone.
Any info would be much appreciated
