Magnesite can be found all over the world, including the United States, Austria, and Brazil. It's best used in pendants and earrings, and I'd recommend against using it in rings and bracelets that would be bumped often.
Natural magnesite is soluble in saltwater, so be sure not to wear your magnesite jewelry swimming! Magnesite is also fairly soft and scratchable, rating a 3.5 - 4.5 on Moh's scale. This is softer than real turquoise, which has a hardness of 5-6. If your magnesite is dyed, to protect the color, it's recommended you clean the jewelry with a cloth rather than dipping it in a cleaner or cleaning solution.
Metaphysically speaking, magnesite is prized for aiding in meditation. It is said to relax and soothe the mind, allowing a deeper experience. It is also said to open the heart chakra, help one to learn to love oneself, and raise self-esteem. A natural remedy for restless sleep is to place a piece of magnesite under your pillow - provided you don't have the sensitivity of a princess...!
Linda Barton wrapped this turquoise magnesite stone in copper wire, and hung it on a necklace with copper and real turquoise beads.
