I found this in a wood chips tot lot Saturday night and can't find out anything positive on the sites I have tried .
It's a man's ring , 9.4 grams and I see no obvious signs of corrosion . GB means it could possibly be gold covered silver or some other metal but the meaning of the "I" before the GB is not mentioned anywhere .
Any jewelry experts out there ? I have no idea if the stone is a genuine diamond either as I don't have a tester .
