The Norse tree of life is a large ash tree named Yggdrasil the world tree, which connects the Nine Worlds and is the center of the cosmos. The gods go to Yggdrasil daily to assemble at their things. The branches of Yggdrasil extend far into the heavens, and the tree is supported by three roots that extend far away into other locations. The pendant diameter is 34mm/1.3 inches.

The brass pendant is made from quality brass and comes with a 22-inch long bronze-colored chain.
