The mineral magnesite (magnesium carbonate) has the same crystal structure as calcite (calcium carbonate). The stone's porosity and low-luster make it a good candidate for enhancement — magnesite is often dyed to resemble much-pricier turquoise.

Magnesite is said to assist in creative visualization, help bring peace in meditation and stimulate passion. It is also believed to help strengthen the bones and teeth, and to help lessen the symptoms of PMS.
