Rhyolite beads and peridot color Venetian translucent beads make me think of the ocean waves and bubbles. The beautiful patterning on the stone beads looks like little fossils embedded. The toggle clasp is Sterling silver. Length is 21 inches. These colors will carry right into the fall-winter Pantone layout of colors for this year as the herb colors that they show. A winner for sure for the discerning fashion lovers.
