This necklace has three (3) curved beads each approximately 47-50 mm and 4 (four) 8 mm beads, all black-based with raku frit which brings out varying shades of blues, golds and greens. Eight (8) silver spacers separate the beads. It is approximately 18" long and has a sterling silver lobster clasp and sterling floral link. The black stones are Czech glass beads. I use Wire Guardians and Sterling Crimp Covers on all my jewelry so the stringing material won't fray.
