With a play of colors to rival fine opal, from bright red and orange to intense greens, blues and purple, and with the hardness and durability of agate; Fire Agate is one of the most unique, rare and sought after gem chalcedonies in the world. Slaughter Mt. on the San Carlos Apache Indian Reservation in Arizona has long been recognized for producing the finest Fire Agates in the world especially prized for their bright intense colors. Mining and trade in Slaughter Mt. Fire Agate is carried out by members of the San Carlos Tribe, our friends; Mike, Ray, and Charles Vargas.
