Mother nature is amazing that she can make these colors. Blue apatite is so striking I thought it would make a great triple magnetic bracelet or a necklace. The other beads are turquoise wrapped in copper, Thai silver plated in 22k gold, ruby, carnelian, Roman Glass, sapphire, turquoiise, labradorite, crystal and apple coral. It measures about 20.5 inches. Custom lengths available upon request. Magnetic clasp is really strong.
