Beautiful and great collection of stones. They work so well like mini canvasses. I pick one up now and then that looks interesting. This stone in the picture is one of the most interesting I've found. It's fused with two distinct halves. The white part is like crystal and the dark is mixture of crystal and rock.
Wowww I love it but not to paint it but to have it like this as a decoration!!!!
It is tempting to paint it. The dark part could look like a forest and the white part would be a mountain of snow or the sky with an aurora :D
You could paint it!!! Cheer up!
