This choker length 16mm lava stone and red 10mm crystal custom hand beaded & knotted necklace set uses black matte metal findings that need a little extra care. Don't get me wrong as they are coated nicely, but may scratch as any metal. The toggle clasp has a small rhinestone for a little extra touch and the pierced earrings have been treated with a coating for sensitive ears to allergies. The earrings are beautiful crowns with red crystal accents.
