Black Tourmaline comes in a few different formations. Some of the crystals have striations on their surfaces, others are double-terminated. Some are just rough chunks, and some form very high-quality, delicate crystals.
The striated crystals usually originate from Brazil. They are great for speeding things up, like manifesting, karmic cycles, and more. They are also great for enhancing the energetic vibration of the stone itself. The striated formations of the Tourmaline work really well for protective grids. This is because they have a somewhat amplified field of energy, as compared to the other formations of Tourmaline.
Since Black Tourmaline is mainly a protective stone, it can be used to create strong perimeters of protective energy.
You can create a crystal grid out of Black Tourmaline. You could do this for a small space, or even for your entire home or property. The simplest way to do this is to place one piece of Black Tourmaline in each corner of the area that you would like protected.
The natural, double-terminated Black Tourmaline crystals (usually originating from China) are wonderful used in an environment where you cannot use more than one crystal (i.e. if you have limited space, have small children and can’t have crystals in the corners of the space, have a limited budget and don’t want to purchase more than one crystal, etc). You can actually place one double-terminated Black Tourmaline crystal in your living room or your kitchen (or any place in which your family spends a lot of time).
Having a Black Tourmaline in your environment, in your energy field, or in your space is very important because it will help transmute any negative energy into something positive. It’s also very shielding. So, wearing a piece of Black Tourmaline in jewelry can be helpful.
