This donut stone (pi stone, to some), of Picture Jasper, is about 1 1/3 inches across and looks like blown sand, in browns and grays, drifting in a desert or on a beach. The cord is knotted linen and has slider beads that permit the stone to hang anywhere from 11 1/2 inches to 15 inches below the center back of the cord. The cord extends to hold the donut stone in place with dramatic black stripes of cord crossing the browns of the stone. The top of the stone and the length of the cord are accented with tiny wood beads in aqua or purple. The slider beads at the back of the cord are purple glass.
