Smoky quartz is a stone that aids in grounding and is able to transform negative energy into positive. Connected to the Root Chakra, smoky quartz enables you to connect to the earth where your negative energy can flow to and dissipate. Smoky quartz cleanses the aura and leaves you with feelings calm and serenity.
Physically, placing a smoky quartz on an area that is in pain (headache, cramps, back pains, etc) can help relieve it. It also facilitates removal of toxins and regulates bodily fluids.
