This is a Moon Phase crystal grid made out of Birch wood. This is just for the grid, stones must be purchased separately.
Themoon is a feminine symbol, universally representing the rhythm of time as it embodies the cycle. The phases of themoon symbolize immortality and eternity, enlightenment or the dark side of Nature herself.
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.
