John, its just the amber the way it is in its current condition. Its cracked through and through and has air pockets within and deep crevaces about the surface. I was able to cut enough from one piece to make a spacer I think consistant enough for a knife but I need two for the knife I wanted to make and I can't see getting another good spacer from this stuff. Its beautiful stuff if you like collecting amber but not good enough for knife material. Thankfully I don't have that much in it. I got 5 pieces for 55 bucks and only used one piece so I hope to recover some of that by putting it back on Ebay. I'll explain my sad story there too so no one else tries to use it as I did.
