It helps us 'go to' those places in us that make us uncomfortable and to look at those things we'd like to deny. Most important of all, it says just accept them-the positive and the negative. Do it happily. That explains why we may feel so calm and generally loving of ourselves and others whenever we wear it. And why we should wear it more often. 
 It can help to remove negativity balancing the mind, body, and spirit. Smokey Quartz is grounding and protective.
