You need quartz if you're sad, anxious, fearful, hurt, angry or alone. If you need clarity, rest, balance, grounding, courage, joy, peace or strength. Im telling you, its the stone you need, if you had to choose only ONE stone (in some kind of hell!)
Known as ‘The Master Healer’ quartz has said to have the ability to absorb, store, release and regulate energy. A stone for everyone, quartz focuses on negative energy and stimulates positive thoughts and feelings in its place.
A stone for all the chakras and is a great all rounder crystal.
