Celtic Chic or Viking Style

Sometimes things like this unusual gold pendant come into the office.It's big, it's beautifully crafted, it's heavy. But what is it? Celtic? Nordic?
And what do we do with it?

Miss de Ville has decided that she is all over this pendant.

Worn with a long chain, she has dubbed it "Ghetto Viking" style.

Yeah, it's definitely Viking-esque.

Maybe if I hang it from some multi-colored gemstone beads and attach long boho tassels with feathers, Jill will covet it.
