WILD HORSE MAGNESITE FOR SALE
Wild Horse Magnesite, also known as "Crazy Horse" or "Appaloosa Stone", is a semi-precious, brown-red and white gemstone that comes from near the Globe Copper Fine in Southestern Arizona. It's a metamorphic rock that contains plumes of white magnesite that can often have a grey to brown mottled appearance within the surrounding red-brown hematite-rich rock. This magnesite formation occurs during low grade metamorphism (200 to 320°C at low pressure) when magnesium-rich rock comes into contact with a carbonate-rich solution.
