John Thanks so much for your information on both the black & white "zebra" as I call them, and the two-layer yellow mosaic with both black & white murrine and trail decoration. I really like knowing that the black & white beads are an imitation of Krobo black & white beads. No one seems to have seen them much before - are they scarce? And I really love the big yellow mosaic beads - I already have a few of the smaller size and I was astounded to see these big ones. I didn't know whether to call the murrine composite, there seems to be quite a bit of distortion in them. Thanks again, your info was a big help. Paul
