Your grandfather certainly had a good eye...It is a beautiful stone...None of those ugly shadows that you sometimes see in poorly cut antiques...this is clearly not one of them. Best of both worlds. Antique and looks like a very well cut, lively stone indeed!
I''m so glad I was able to get some better pictures; because as you can now tell the first ones really didn''t do it justice at all. Hope you all have happy holidays.
