The Home Protection Grid Set was created to help you protect your home from unwanted negative energies.

Black Tourmaline absorbs negative energies and helps protect you and your home on a physical level.

Selenite also has beneficial protective qualities, except it's job is to protect you and your home on a spiritual level.

When combined, Black Tourmaline and Selenite has you covered.  In this set, you will receive four raw black tourmaline pieces and four rods of raw selenite.  

After cleansing with sage smoke or with a bell, take one of each stone and place them together in each of the farthest four corners inside your home.  It doesn't need to be exact, just the best you can.  Once they are set into place, take a few moments to imagine them all connected to each other, creating a protective boundary around your home.  Thank them for their service, then go about your business. 

Leave them in place for as long as you are able.  If they get moved by a pet, or from Spring cleaning, go ahead and repeat the process.  This type of grid is meant to be set up and forgotten about, left alone to do its job.  You shouldn't have to reset it very often.
