Raw black tourmaline chunks

You will get one rough black tourmaline chunk intuitively chosen. If I pick a very small piece, I will pick two to make up for it.

Black Tourmaline is the stone of protection and as a black stone is extremely good for grounding and bringing in some balance. 

Black tourmaline is the protective crystal, it protects your energy and your home. Putting a piece of black tourmaline in each room in your house can help protect the energy of your house keeping the negativity at bay.

It's also brilliant to carry with you in a pocket or in your handbag, think of it as a shield around you for negative energy and anything else harmful to bounce off of. It may not be the prettiest stone in its raw state, but I think it is a fascinating one as it grows in these long strands.
