I first thought this stunning material was "Halloween" Tiffany Stone, but it's a bit harder. I found out that this material was mined by a friend of a local rock club member some thirty years ago. He and his partner didn't know what it was, but it looked like it had tiger stripes, and voila! Tiger Jasper! I like it so much I'm going to keep it!

37mm x 27mm x 6mm.   Weight: 50.95 carats.
