Comment: These specimens have caused a great deal of controversy over a long period of time.The derivation of the letters is a story too long to tell here,but if you go to picture 97B gem test in the next pic,it does go some way towards showing some proof that the stones are real. How to fake the letters ? and why are they not even? One set I read sold at auction in the US for 20.000.00 is it true or false? I do not know.But the stones are genuine not fake.One thing is for sure they are interesting.
