Translucent Green Rocks

[Gypsy Heart]

Can someone help me with these. Found today in Northern Wisconsin along a riverbank. Some were on top and others I dug up They range from milky green to translucent green. I am holding one up to the kitchen light to show how you can see through some of them. Any idea?

Put them to a black light or UV lamp and see if they fluoresce, if they do i'll buy them from you
