This piece came to me as in, in my overstock piles. literally was washed up from a dirt pile recently. These piles have been turned at least 5 times since i have owned them. Who would a thought, almost a prefect really nice gem agate cab. The only problem, i dont think it is Montana Agate, maybe Brazil or South American? I just dont know, but it is so nice it really doesnt matter. What do you think?
