Rhodochrosite is a stone comprised of Manganese and Carbonite materials which form Stalagmites and Stalactites in caves found in Argentina and Montana. This wonderful stone has many spiritual and healing qualities. It is a soothing stone which helps heal the heart and spirit. It is also used for asthma, poor eyesight and to detoxify/heal the blood and liver. Most importantly, it makes beautiful jewelry! Many of our Rhodochrosite stones are Native American made. Those pieces will have a signature or initials on the back. Each Rhodochrosite stone is unique in color and design. These wonderful pieces are sold by design. They have been cut from the same stone and are as similar as nature will allow. We recommend that you use a sterling polishing cloth to keep your sterling silver clean. The polishing cloth is safe for use with all our wonderful stones. As with all of our beautiful jewelry, your satisfaction is 100% guaranteed.
