Smoky Quartz for Positive Energy

I picked up this amazing piece of smoky quartz last weekend at Pisces Trading Company in Portland. Smoky quartz is a quartz variant that is strongly grounding, protective, and cleansing. It also transmutes negative energy to positive, so I use it a lot. I actually have smoky quartz near my front door so all energy that comes into the house is positive, and I've sprinkled smoky quartz chips all around the perimeter of my house and property so the energy that crosses to my home and property is cleansed and positive.
