Many years ago when my grandfather was in the military (approximately 60 years ago!), he was in Brazil. He brought back some rough emeralds that he just had sitting around. He passed a few years ago, and I got the rocks. So I bought a tumbler and went to town. There are some very clear emeralds in there, and was wondering who would give me an honest opinion on them as far as wether they are worth while or not. I don''t want to ship Emeralds to someone I don''t know, have them keep them and tell me "Nah, nothing worth while." Meanwhile, they''re cutting them up for their own use. Can anyone point me in the right direction?
