The fossil ivory of mammoth is preserved in the Siberian permafrost. This 10,000 years old material is a rare one. The core part of the tusk keeps its light ivory color. The surface however is in contact with minerals which taint the ivory with various shades. The color of the ivory crust significantly varies depending on the nature of the soil in which it was found. These colors can be bright, ranging from blue to yellow, or from red to beige
