Fire opal is mined in the Mexican states of Quéretaro, Hidalgo, Guerrero, Michoacan, Julisio, Chihuahua and San Luis Potosi. The most important mines are located in Quéretaro. Fire opal was discovered there in 1835 and some of the mines are still producing today. The state of Querétaro (pronounced ké re tar oh) is located in the central part of this vast country. From 1965 until 1975, there was a virtual “opal rush” at the Querétaro mines. It’s told by miners from that period that opals were so plentiful that they were sold by the sackfuls by thousands of miners in the area. As with everything, this prosperous time ended a short decade later and today opals of the same gem quality are much harder to find.
