History & Traditional Uses
Black Tourmaline is a variety of Tourmaline, and is one of the most popular crystals for spiritual practices. Tourmaline can come in many colors and forms, including green, black, pink, red, blue, and even a variety called Watermelon Tourmaline. No other crystal comes in as many varieties as Tourmaline does. This stone is a complete aluminum borosilicate with a hardness of 7 to 7.5.
Records of this stone date back to ancient times in the Mediterranean. During the early 1700s, this stone was traded from Sri Lanka to Europe by the Dutch. Tourmaline first gained popularity in 1876, when George Kunz sold a piece of Green Tourmaline to Tiffany and Co. Since then, it has gained in popularity. This stone can be found on every continent, however, fine crystal pieces are still considered rare and drive high prices. Black Tourmaline specifically forms in a wide variety of sizes from half inch pieces in Nepal to large Brazilian pieces that can weigh several pounds. Some of the best Tourmaline crystals come from Brazil, Africa, Pakistan, and Maine in the US. 
This stone helps to provide a grounding path for Light to enter the Earth plane. It is a very powerful protection stone, and is often what many will turn to as the stone to clear negative energy. Black Tourmaline, along with many other crystals, works by absorbing the negative energy around you so it doesn’t penetrate your aura and energetic field. This is also a good stone to use to protect your home, and can be placed at the front door. This stone is also grounding and works well with removing blockages in the Root chakra.
Black Tourmaline can help you remove yourself from obsessive or compulsive behaviors and release anxiousness. By deflecting negative energy, this stone allows you to move through anxious thoughts and can keep you feeling calm. This stone is also purifying, and could be kept under a pillow or on you to cleanse anxieties, anger, and feelings of unworthiness.
