This is a Spiral crystal grid made out of Birch wood. These are made to order, you can choose between approximately 4, 6, 8, 10, 12 and 14 inches in diameter and 1/4" thick. This is just for the grid, stones much be purchased separately.
The spiral has become a powerful symbol for creation and growth, used by many ancient cultures and religious traditions. Some say the meaning of the Taino/pre-Taino spiral symbol represents cosmic energy and sweet water.
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.
