This genuine amber necklace has very interesting shaped beads that aren't seen very often. The center bead measures 1 1/8" X 1/2" and has an indentation across the top and bottom. The other beads measure 3/4" in length approximately 1/4" wide. They graduate to a smaller size near the clasp. They are all a little bit different in size and shape from each other. Some are completely clear and others have many inclusions. The length is 21 3/4". The closure is a screw clasp. Excellent condition.
