Clear Quartz is used to raise your vibration and for clarity of thought. It is often referred to as the "master healer," and has been known to make the crystals around it more powerful! It's been know to stabilize emotions, and relieve stress. It is an excellent addition to a bowl of salt for crystal clearing.
Anyone who believes in the energy of crystals should really have some of these literally on hand. (There is that damned pun again! I gotta stop this! Hahahaha!)
Chakras: All 'dem!
Elements: All 'dem too!
Astrological Sign: Pretty much all of us!
