This necklace is made with natural Jupiter jasper which is a true form of jasper. Jupiter jasper is named for its radial banding that resembles the planet Jupiter. It has beautiful rich chocolate brown and mocha colors giving it its beautiful look. I have taken large 12mm round Jupiter jasper beads and separated each with a 4mm gold plated bead. Then I have linked 8mm round Jupiter jasper beads on either side of those. This necklace measures 19.5 inches long and has a gold plated lobster claw clasp.
