Mjölnir is the hammer of Thor, the Norse god associated with thunder. Mjölnir is depicted in Norse mythology as one of the most fearsome and powerful weapons in existence, capable of leveling mountains.

This Mjolnir necklace has runes as added accents. Runes are the letters in a set of related alphabets known as runic alphabets, which were used to write various Germanic languages before the adoption of the Latin alphabet and for specialized purposes thereafter.
