This is a natural gemstone, Black Onyx and Black Spinel necklace. This elevated design combines the hot paperclip chain craze with real gemstones. The onyx adds lots of shine and the black spinel adds the sparkle. The chain links are somewhat chunky at about 1/2” in length. The necklace is adjustable up to 21”. These Black Onyx beads are 8mm and the Black Spinel beads are 3 mm. The lobster clasp and paperclip link chain are gold tone metal.
