I'm selling agates all together

I have four beautiful agates they're about 4 inches by 5 in and there's one of them that's a little bit smaller than that it's about 4 inches by 3 in the other ones are four and a half inches by 5 in they weigh about a pound each I couldn't tell you really exactly what kind of agates they are but they have been polished and they're beautiful and most of them are always marked that they came from Brazil the bigger I get is pretty tall and the ways of healthy 4 lb at least as beautiful light blue and gray colors to it I would say it's about 8 in tall 5 and 1/2 in wide and weighs about 4 lb easy
