   Is the blue more than skin deep?  May just be a surface material.

Did check the hardness? The crust looks like it could be agate or chalcedony. Is it translucent or is it opaque? (Hold a small flashlight on the cut edge and see if light comes through)
If you really want to know you need hardness, streak, and specific gravity ( I know low but it is too much trouble)

I would vote for agate or chalcedony. Hard to tell by a picture. Did you cut a slab? Sometimes the color will fade as it gets thin, I hope not it is a pretty rock.

Looks like Big Sandy Creek Jasper from the Stone Canyon area of CA.
Note the blue color in this jasper.
