We have only 1 strand of each of these vintage (maybe even antique) glass beads from Morocco. They are made by layering different colored glass and then shaving away to make a pattern. Each bead is hand done so they all look a little different. The strands some with the brass spacers. You could wear them as they are as a necklace, or take them apart to make something even more amazing.
Beads measure approximately 5 mm by 4 mm (3/16" by 1/8")
Strand measures just over 40cm (16") 60 glass bead on the strand + brass spacers
