Jasper is an opaque rock of virtually any color stemming from the mineral content of the original sediments or ash. Green jasper was used to make bow drills in Mehrgarh between 4th and 5th millennium BC. Jasper is known to have been a favorite gem in the ancient world; its name can be traced back in Arabic, Persian, Hebrew, Assyrian, Greek and Latin. On Minoan Crete, jasper was carved to produce seals circa 1800 BC, as evidenced by archaeological recoveries at the palace of Knossos. This particular specimen of Jasper is red, a common occurrence due to iron inclusions. It's large enough to serve as a paperweight, and makes for a great sample to be passed around in earth science classrooms. Makes a great gift for the mineral collector in your family!
