Anthill or Chrome Garnet

Anthill or Chrome Garnet comes from the four corners area of Arizona in a remote section of the Navajo Nation. When ants build their colonies, they bring up garnets to the surface and this is how they get their name anthill garnet. In the 1800’s the Navajos used water-worn and rounded anthill garnets as bullets.
