Apatite stone with tourmalized Quartz and Lava rock beads. This striking necklace really stands out with the bright blue of the Apatite stone. I use double strands of stretchy Gossamer floss of 0.45mm, and tie a quadruple square knot which has been glued also. The silver spacers are silver plated over high quality lead and nickle-free pewter. Use your essential oils on the Lava rock beads! The beads are 8mm in diameter. Your new treasure will arrive nicely packaged and ready for gift-giving.
