First off: mixed stone means you don't know what stones you'll actually get. Sometimes the strand will be more to your taste than other times. My rating is for the strand I received. But it's still a good option when one can afford or have use for a whole strand of one type of stone only. The large hole makes them perfect for leather, rattail and cotton and other thick cords. Some of these have holes large enough to pass over the magnetic clasp on the steel cable chokers.
