This is such a lovely and interesting necklace. It is two strand with one strand has another strand tied to the lower half. It is a lovely turquoise with gem stones and long mother of pearl. It has nice stable turquoise in a rectangle nugget shape. A shell toggle switch is the closure. The necklace is 17 inches and the added strand is another inch drop and the lower strand is a couples of inches below that. This is an very well put together and makes a beautiful necklace, From the High Plains of Kansas. Terrific with a turtle neck or an open neck.
