Diopside Chip Necklace. $15.00. Not stretchy, however, fits over all heads. The simple design is perfect for everyday, comfortable wear, and can even be wrapped and worn as a bracelet. Diopside is a stone that connects with the Earth and the heart. It works with the root, earthstar, and heart chakras, and helps you heal through the “heartbeat” of the planet. Green diopside in particular is useful for women’s reproductive health.
