Such lovely beads as these are made from naturally shed horn. So, you needn't worry that any animal suffered to provide these for us. We purchased these in the 1990s from the individuals who made the bead.
The stripe in the center of the bead is not a stripe at all, it the s the stringing hole! Of course these are all a tiny bit different as they are made individually by hand. Each measures 5/8 inch high by 1/2 inch wide.
The caramel amber color makes the bead almost delicious.
