The beads give this necklace weight and contrast to the solid 14K yellow gold spacer beads and the corrugated ball clasp. There are also glossy rectangular Black Onyx beads and silvery white Cultured Pearls. This necklace is an amazing 36" rope so you wear it long, wrap or double in length making it more versatile. Hematite beads are 8mm, Onyx are 13mm long and the pearls are 5.5mm. The solid gold clasp is about 8mm and has an extra bar to catch the slide in case it came loose for added security. Beads are knotted in groups but not in between each. Pre-owned the necklace has a few dings or dents in some of the 14K spacer beads. Otherwise clean and beautiful!
