Black Onyx beads are hand strung to form this classic single strand necklace. The beads are tiny measuring about 3.0mm. This is a beautifully tiny, and delicate onyx necklace. You could wear this alone or stack with other necklaces for a layering effect. I have hand strung these beads using a premium beading wire that has beautiful drape and it fastens with a sterling silver lobster clasp. The necklace is available in 16" to 42" lengths.
