Creating a Gem Elixir. Caution Be careful of the stones you use directly! Most "-ites" are not water soluble. Degrade the stone or crystal and it can be toxic. Most quartz is very safe though provided there are no exposed metallic inclusions.
(I wouldn't term this a "witchy tip.) It's said, washing the face in water charged by rose quartz will help fade wrinkles and keep the skin young. Also, holding rose quartz to bruised skin may reduce swelling.
