Where did you get it? Did you tumble it to polish it? How heavy is it in comparison to an ordinary rock of the same approximate size? How hard is it? Will a file scratch it? Will it scratch glass?

It sorta reminds me of glass slag, are you sure it's a natural mineral?

Looks like a couple of pieces or kneaded play-doh. However, if a rock it is a likely a jasperoid or agate.
