The Healing Amber Baltic Amber Teething Necklace is a 13-inch teething necklace made from raw Baltic amber, handcrafted by artisans in Lithuania. Baltic amber, a fossilized tree resin, contains succinic acid, which is believed to have natural pain-relieving properties. Available in various colors and unique bead shapes, this jewelry is meant to be worn (not chewed) and should always be used under supervision. Raw amber will polish over time.
