This is just a wonderful old trade bead necklace probably African in origin. It is mostly strung with turquoise colored glass beads but there are also a few cobalt, yellow, orange, red and clear. The beads are strung on twine which looks to be original. The average size of the turquoise beads is 3/8" X 1/4" but some are smaller and some are larger. The shortest strand measures 26.50" and the longest 29.50". With the exception of the beads being somewhat dirty they are in excellent condition.
