Clear Quartz Necklace

Clear Quartz is recognized as the stone of power. This crystal protects against negativity, connecting you to your higher self. It is also told to relieve pain if placed on the area of discomfort. (Not all crystals look exactly the same, some may look different than others, but they still carry the same effect.)

Like most crystals, Clear Quartz can be cleaned in multiple ways. Placing it around other crystals, setting it in saltwater, and running it over water are some useful and convenient methods. 
You should clean your crystal if it were present during a negative event if it is new or you haven't used it yet if it feels weak or unbalanced and after rituals.
