Gorgeous adjustable (!) hypersthene and silver ring. The most beautiful black stone!
It is sterling silver
Regarding the metaphysics of hypersthene:
Hypersthene is beneficial during meditation, allowing you to reach a state of tranquility and calm so that you can connect with higher realms and receive guidance. It also helps you to achieve a state of flow for manifestation.
While mostly associated with the Third Eye Chakra for clairvoyance and clairaudience, as well as the Crown Chakra for connecting with higher realms and guidance, this stone can also be used with the Solar Plexus Chakra. It energizes your confidence, self-love and self-respect, helping you to value your worth and gifts.
Physically, Hypersthene can be used as support after surgery and is great for relieving aches and pains especially of the shoulders and tendons. It is beneficial for blood disorders (anemia and Leukemia), as well as disorders of the intestinal tract and an overactive pituitary gland.
