GROUNDING, HEALING & PURE
A Grain stone is defined as a limestone consisting of grain-supported particles without any mud matrix. This is an assisting stone used to enhance healing properties, encourages purification, reminds us of our innocence, grounds and centers us and entices positive thoughts. Due to its grounding make-up of clay, sand, organic remains, iron oxide and other materials, they come in different colors. Tan colored stones are connected to the Root Chakra (connection to earth, survival instincts, self-preservation). Affirmation: I am grounded and calm.
