The black tourmaline necklace is the most widely worn protective shield in lithotherapy. This deep, matte black, striated with characteristic vertical lines, worn at the base of the neck, covers a wide energetic field and protects all the upper chakras. This is what makes the necklace particularly effective compared to a bracelet: positioned in the center of the body, it acts on a larger area. Black tourmaline, also known as schorl, is an iron borosilicate with real pyroelectric and piezoelectric properties, meaning it physically interacts with electric fields. This particularity fascinated Dutch physicists as early as the 18th century and underpins its reputation as an anti-wave stone in lithotherapy.
In lithotherapy, the black tourmaline necklace is known for being a gentle yet constant absorber of negative energies. Unlike black obsidian, which reflects and confronts energies, black tourmaline absorbs and neutralizes them without turmoil. It is a passive and silent protection suitable for everyone, including sensitive individuals and beginners. When worn around the neck, it traditionally protects against both the energies of others and electromagnetic waves. It is recommended for caregivers, teachers, therapists, and anyone exposed to charged environments. Black tourmaline pairs very well with labradorite (double protection), amethyst (protection and appeasement), or rock crystal (purification and amplification). For maintenance, a rinse with clear water and recharging in moonlight or on a quartz cluster are sufficient. With a hardness of 7 to 7.5 on the Mohs scale, it is a solid and resistant stone for everyday wear.
