This jewelry is handmade using original Baltic Sea 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. Fossilized tree sap that has been preserved for millions of years under the sea. It is a true gift from Mother Nature. The string on 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 jewelry fastens with a classic screw clasp that opens and closes easily.  Our pieces are beautifully made, comfortable, lightweight, and radiate energies of peace and calm for the wearer. Baltic Sea Amber Jewelry is made for wearing, not for chewing.  Our jewelry is not designed to be an amber teether or teething necklace and it should never be placed in the mouth.
