Charm size. 5/8” height. Slightly domed section in the fully developed form. Made by the open face mold technique. It is said that Hrungnir, with whom Thor dueled (assisted by a sorceress), had a heart of stone. For Vikings, the heart stood for bravery, fortitude, loyalty, integrity, all attributes of the warrior. Professionally refurbished with the silver surface restored, on sterling silver neck chain for contemporary wear. Gift boxed with certificate of authenticity. Charming.
