This classic necklace has 1/2 inch black beads I assume they are Onyx as they are very cold and it suppose to be a gem-stone necklace. The necklace is 18 inches long and there is a large silver and brass overbead that can be slide to where you want it. The beads are beveled and are knotted between. The necklace is heavy and has a toggle closure. Perfect for that thin neck person. For you from Kansas.
