Baltic amber contains a substance called succinic acid.  When worn on the skin, body heat causes the amber to release an oil containing succinic acid, which when absorbed into the skin, works to block pain and reduce inflammation and is commonly known as "teething jewelry" in Europe.  All amber bracelets are double knotted and feature a durable screw-clasp for child safety. 

Bracelet Measures 5 - 5.5".  There are also coordinating soothing necklaces as well.
