Tiger Tail Jasper
Tiger Tail Jasper comes from Mexico. I've also heard it called Flash Jasper because when it is polished the hematite swirls cause glints of light to bounce off the stone. It's typically yellow and oranges with streaks of the metallic hematite.
I bought two slabs from a vendor at a gem & mineral show and I'm quite certain I paid too much. Oh well, gotta credit the dude for his salesmanship.
