Amber:

Amber offers soothing energy and helps calm nerves. It can be used as a symbol for the renewal of marriage vows. It is sometimes used as a treatment of goiter, kidney and bladder disorders. When rubbed with cloth, amber becomes electrically charged and can attract small particles. Amber is found in the Baltic seabed, also in the U.S. and Dominican Republic. The stone is weightless therefore an ideal gem for persons who do not want heavy items hanging around the neck or from the ears. Those with "spring" coloration can wear amber.
