Mystery Jasper Slab! Lapidary Stone Slab!

This is a jasper from an unknown origin that we picked up in an estate sale.  It has some pretty awesome pattern and coloration, and it looks like it should polish and cab well!     Measurements (inches - longest - approx): 3.6 x 1.6 x .23   The last photo has been taken dry so that you may see any defects. The other photos have been taken wet to simulate a polish.
