It is said that Jasper absorbs negative energy, including environmental pollution and radiation. It balances Ying and Yang. The Tree of Life reminds us of growth, renewal and immortality. Be reminded of a bright future, even during times of stress, while wearing this bracelet.The beads are 6mm and I string them on a very strong stretchy cord. The tree of life charm is 15mm. On request, I can send it in an organza or burlap bag.
