Our Recharge Sacred Geometry necklace features Black Spinel for the release of negativity and the creation of space for positive energetic flow and the Sri Yantra. The Sri Yantra can be used as a inner tuning fork for meditation and is the geometrical representation of Om. The point where the triangles meet is considered to be the connection point between the physical and spiritual world. The 7 circuits of the Yantra are linked to the 7 chakras. This includes an 8x11 millimeter hand cut faceted Black Spinel hexagon gemstone on a 16" Mighty Miracle Cord with a Sterling Silver extender allowing it to be worn up to 18"
