These are lovely little black onyx beads in between glass seed beads in gold, silver or rose gold. The black onyx beads are 4mm and inbetween each are tiny seed beads for accent. The beads are strung on a heavy duty stretch cord. The ring is in a size 7 US but easily fits one size up or down from there. If you would like a different size please just leave the information when ordering and I will make it to size. Each one comes in a small jewelry bag ready for gifting.
