Raw tourmaline 

The most protective of all crystals, black Tourmaline supports the

base chakra. It is said to encourage balance and neutrality, release

stress, and discharge tension. It also known to dispel anxious feelings

and negative emotions, creating a relaxed environment. This stone

can apparently be used in homes as a protection grid.


Please note that this is a raw stone and May "flake". That's normal.
