These are all based with Idaho Crystals and Stones, tumbled smooth. The colors of the crystals/stones are aligned with the elements, and embedded with herbal blends designed and aligned by me in  ritual practice. Each one is also ritually attuned to the Elements once completed. Red for fire in the south, Blue for water in the west, Green for earth in the north, Yellow for air in the east, White for Spirit that binds them all together. They can be arranged together in one location or set in each quadrant aligned with their direction with the White/Spirit in the heart of the home. This set can bring balance and calm to an environment.   The pyramids are slightly smaller than my base ones, but still pack a punch energetically.
