This is a Scarab Crystal grid made out of Birch wood. Approximately 6 inches in diameter and 1/4" thick. This is just for the grid, stones much be purchased separately. The scarab beetle was sacred to Khepera, the Egyptian god of creation, resurrection and immortality. As a symbol of the spirit, the beetle carries messages that bring our attention to renewal, spiritual maturity, and the powerful influences of the invisible side of life. The moon is a feminine symbol, universally representing the rhythm of time as it embodies the cycle. The phases of the moon symbolize immortality and eternity, enlightenment or the dark side of Nature herself. The moon is Yin energy. Crystal grid and healing sets are groups of stones that go together for a purpose. Sets of crystals and stones are used for ritual magickal or spiritual crystal healing purposes or with Reiki-Seichim energy work for healing. Some are generalized and others have specific purposes.
