Rainbow Fluorite in a dazzling array of these beautiful colors. Hard to believe that these are natural stones and not painted with a brush. The colors range from Purple to Green to Teal with some of these stunning beads striped with all of the colors. The Rainbow Fluorite nuggets have been all hand-knotted to separate one bead from the other. I added five 10mm matching beads at the back of the necklace, all separated by Sterling Silver links so that you can wear the necklace at varying lengths from 16 inches to 19 inches which give you versatility. I love this necklace - you will too.
