TOURMALINE BLACK PYRAMIDS - 70MM

The 70MM Black Tourmaline Pyramid is the most powerful available room-level protection tool in the ShriAAUM collection. At this size, its piezoelectric properties — the ability of tourmaline to generate electrical charge under mechanical pressure — create a measurable electromagnetic field extending several feet from the pyramid in all directions. University research on tourmaline's piezoelectric and pyroelectric effects confirms it constantly emits negative ions and far-infrared radiation, both of which have documented beneficial effects on air quality, mood, and immune function.

In Vedic Vastu science, the placement of heavy, dense black objects at the corners of a building creates what the Vastu Vidya calls "Bhu-grounding" — connecting the space to Earth's stabilising frequency. The Black Tourmaline Pyramid is the crystal embodiment of this Vastu principle.
