Deep Green Nefrite is sourced from the high Andes of Perú. Its rich, earthy tone and dense, durable composition make every carved piece entirely unique. Closely tied to the heart chakra, it is said to bring a natural calm to any space, ground the mind, and restore emotional balance. Metaphysically, it is believed to support the nervous system, foster physical vitality, and revitalize the body's energy.
