Bliss Manufacturing, a more than 100-year-old, family-owned company, makes all of its jewelry in the USA. All Christian jewelry is die-struck, the same way the U.S. Mint makes coins, which produces rich detail. Bliss Manufacturing stands behind its Catholic jewelry and honors a lifetime guarantee. Our Medals are sprayed with a lacquer coating to protect the finish. Should any of our medals or chains tarnish or have defects, we will either repair or replace free of charge. Avoid exposing the medals to household cleaners or chlorinated water. These chemicals can damage the medal.
