Magnesite

(Also see Howlite)All the material on the market over the last 20-years has come from Zimbabwe either cauliflower-shaped nuggets (known as Turqureniteù when dyed to look like Turquoise) or in massive white form with grey blotching (incorrectly known as Howliteù, especially when dyed blue). High in magnesium, this stone treats bone and teeth disorders. It helps prevent heart diseases by dispensing cholesterol, has a calming effect on nervous and stressed people, and stimulates new ideas and positive thoughts.
