7" stretchy bracelet made with genuine 12x18mm Fluorite nuggets & genuine Swarovski bicone crystal beads. Fluorite is the mineral form of calcium fluoride. It has a rainbow of colours, mostly in the light green and purple families. The chunky look is very "in" and this bracelet is so much fun to wear. Since it has purples and greens it can be worn year round. Fluorite nuggets will vary in colour.
