This tiny rams head Thor's Hammer is just for the ladies. It is made of solid sterling silver with amazing detail for a piece this small. Measuring a mere 1/2" long by 7/16" wide, it is dwarfed by the 5mm jump ring it hangs from.
The uniquely shaped symbol subsequently became a very popular ornament during the Viking Age and has since become an iconic symbol of Germanic paganism. it is suspended on a 18" sterling silver chain.
