I've made this necklace using opalite coins and round beads, separated with clear lustre glass beads. The last 2.5 inches / 6cms of each side are just lustre beads for a more comfortable fit around the neck. I have completed the necklace with a silver-colored filigree box clasp.
Please note that opalite is a man-made stone and not a gemstone - but it's still pretty!
The necklace is approximately 23 inches / 54 cms in length.
