Generous 5 turquoise hand blown beads with silvery blue polka dots are threaded through black cords. The beads are hollow so they don't weigh a lot. This makes a great statement and still gentle on your neck. The black cord goes over your neck and adjust with a sterling silver bead at back of your neck. There are rubber spacers between glass beads so there is no rattle. The size of these hollow beads varies: the largest one is 4.5cm and the smaller ones are 3.8cm in diameter.
