This stone means business.  It looks strong and rough yet royal and rich.  Pyrite stimulates creativity, feeds ambition and will help to see you carry tasks out to completion.  It has beneficial masculine energies that promote protection and assertion.  So, go do it and be chic while you do.

And such a great song by OMD:

Tesla girls, tesla girls!
Testing out theories
Electric chairs and dynamos
Dressed to kill, they’re killing me
But heaven knows their recipe
