You need ruby if you have something worth fighting for, or to boost that Friday relationship magick, or if you are an Aries. Put it on the hand you throw punches with, or in the boudoir. Use it when you want to show the world you are both beautiful and ferocious. When your relationship needs a heaping tablespoon of spice. When the doldrums have you down, reach for Ruby and some really red lipstick and come out swinging. Feed your fires.
