Fire agates were created 24 to 36 million years ago, in the times of the most activity of the volcanic activity that exists now in Mexico and in the southwestern part of the United States. Iridescence, known as “fire,” is displayed by this variety of chalcedony, a pinkish gemstone made up of layers of limonite.
