About Wild Horse Magnesite
Wild Horse Magnesite, also known as "Crazy Horse", is a semi-precious, brown-red and white gemstone that comes from near the Globe Copper Mine in southeastern Arizona. It is a metamorphic rock containing plumes of white magnesite, which often has a grey to brown mottled appearance within the surrounding red-brown, hematite-rich rock. This magnesite formation occurs under low grade metamorphism (200 to 320°C at low pressure) when magnesium-rich rock comes into contact with a carbonate-rich solution.
