Are these cute or what? Actually, way beyond being cute, natural amber when warmed by body heat is said to have analgesic (pain relief) and anti-inflammatory effects for teething, etc. Tons of testimonials attest to this fact. These are not for the baby to chew on but to be worn around their necks, not over clothing but next to the skin (any jewelry should be taken off when sleeping/napping). They are genuine Baltic amber and have an easy to use secure screw clasp that matches the amber. For safety each bead is knotted separately so that if the necklace should break only one bead will come off. This beautiful raw (unpolished) amber necklace has lovely natural colored beads. Wash only with water, avoid soaps, lotions, shampoo, etc as these affect the amber. Never leave precious baby unattended with this or any jewelry.
