Raise The Caliber is a national advocacy campaign to end illegal gun violence in America, founded by Jewelry for a Cause President, Jessica Mindich. The Caliber Collection® products are made using the serial numbers from illegal guns and the metal from bullet shell casings that have been swept from crime scenes in America. A portion of the proceeds from each sale are donated to the Caliber Foundation, which supports victims, families and communities that have been devastated by illegal gun violence and helps fund gun buyback and amnesty programs in partnering cities. Destroyed. Never To Destroy Again.
