A moss agate doughnut accented with 3 long blue glass beads suspended on a black leather cord. The moss agate looks like it's a very dark blue-green jasper, but hold it up to a bright light and you'll see the manganese oxide crystals that make 'moss'. It is 25mm in diameter which makes it a little larger than a quarter. Blue beads are 1 inch long and matte. Letter C style clasp.
