Canyon Leaf's amber jewelry is handmade using original Baltic amber that is over 45 million years old. Baltic Amber has some of the highest concentrations of Succinic Acid found in nature, and this is what makes it so special. The string in each of our necklaces and bracelets is knotted by hand in between each and every bead, so should the necklace break (which it should if necessary), the rest of the beads will not scatter. The necklace fastens with a screw clasp that opens and closes easily. All of the teething jewelry is designed to snap with 15lbs of pressure, which is why there is a knot between each bead, for if the jewelry was to break, it would not scatter.
