From "African Trade Beads" Catalog & Reference Picture Collections I found some examples of what are being called Dutch Mulberry Beads, (17th-18th Century), and they are showing some similar colors to the bead I commented on earlier in the thread (color is difficult to match in this situation though). As stated previously I believe I can detect faint traces of very worn same color raised eyes or bumps on that particular bead..?? It's so difficult when you can't see the bead in person and look at it with magnification, of course!
