A pair of identical bracelets. Black beads are lava-stones. The beads with colors could be real gems (quartz, tiger-eyes, lapis, etc.) or could be colored glass crystals. I honestly don't know. See pictures and you decide. Sizes are about 2 inches to 2.25 inches in diameters. These are STRETCHY bracelets. Price is negotiable. I am cleaning out my drawers and selling what I don't wear often.
