Raw green tourmaline is a crystal of striking natural vibrancy. In its raw form, it appears as vertically striated prismatic wands, in an intense green that ranges from deep forest green to luminous meadow green, sometimes translucent, sometimes opaque. The characteristic vertical striations of tourmalines add character to the crystal, and when light passes through a translucent green tourmaline wand, the result is a naturally beautiful display of green light. This is the same stone that Brazilians call esmeralda brasileira (Brazilian emerald) in the deposits of Minas Gerais. The most beautiful specimens come from Brazil, Afghanistan, Madagascar, and Mozambique.
In lithotherapy, raw green tourmaline is considered the most powerful form of this vitality stone. The intact crystalline structure, with its real pyroelectric and piezoelectric properties, is believed to diffuse a deeper, more direct regenerative energy, vitality, and renewal than the polished version. Placed in a living room, it radiates a vibrant natural energy that revitalizes the entire space. On a desk, it provides the dynamism and momentum needed to advance projects. Held in the hand during meditation, it opens the heart chakra with a rising sap energy that deeply regenerates the body and mind. It is a stone of rebirth: it accompanies those emerging from winter, both literally and figuratively. Near plants, tradition attributes to it an ability to promote plant growth, as if its life energy were transmitted to the plant world.
For care, a rinse with clear water and recharging in moonlight or gentle sunlight are sufficient. With a hardness of 7 to 7.5 on the Mohs scale, raw green tourmaline can be handled without special precautions. Its prismatic wands are solid and resistant.
