Arizona is perhaps the best state in the U.S. to search for rare minerals and semi-precious gemstones. There are countless varieties of minerals that are found all throughout the state that are very popular by collectors and jewelers.

Below are some of the most valuable minerals in Arizona and some of the locations where they are found.


The Sleeping Beauty mine of Arizona produces very high and expensive quality of the gem. The turquoise mined here is found in a lighter shade of blue with negligible matrix. These are also known for being one of the most exquisite turquoises found in the United States.

The turquoise from Kingman Mine is also one of the most valuable and sought after stones to be found. The gem is bright blue in color with black matrix.

The Lavender pit mine which is located close to the town of Bisbee in Arizona is famous for its rich blue turquoise stone containing brown matrix and green turquoise as well. Only a limited quantity is procured from the mine presently.

Morenci Mine situated in the southern part of Arizona, though active, does not produce any significant amount of turquoise today.


The Mule Mountains that are located in Cochise County of Arizona are home to the Opal Hill Mine close to the region of Palo Verde. Although the site is famous for its agate, opals have also been discovered here but amount of the stone is not recorded.

Opals have been found at the Burro Creek in Wickenburg. This is a well-known mineral producing area that will produce a wide variety of collectable minerals.

The Southern Sky Opal mines are located in southern Arizona near Tubac in Santa Cruz County. These mines produce a soft blue opal that is highly desirable.


The Mazatzal Mountain Range extends between Gila and Maricopa Counties in the central part of Arizona. These mountains are home to one of the most prominent peaks known as Four Peaks which run from the north towards the south at the southern end of the Mazatzal Range. The Four Peak Mine is located here about 50 miles from Phoenix. The mine is famous for its rich and valuable quality of amethyst that is found here in abundance in the fractures and crevices of the rock formations.

The mine is considered as the most significant source of good quality amethyst production at a commercial site in the Unites States. However, due to the isolated and limited approach to the location of the site, a viable amount of commercial production of the stone becomes challenging and therefore the site is currently being worked only on at a smaller scale.

The deposits consists of precious and rare variety of amethyst and are found in different range of purple color including light purple, darker purple as well as reddish purple.

Another recent site where amethyst has been discovered in Arizona is close to the mine of Santo Nino which is situated in the mining district of Patagonia in Santa Cruz County. The mine is located on the northeastern side of Mount Washington. The exact location of the amethyst deposit can be found towards the west from the mine on the adjoining side of Mount Washington.


Jasper is found in many places in the state of Arizona. It is found in streams and can be spotted on the surface of the ground in places with little or no vegetation. Jasper and agate is available in Arizona in much larger quantities than most other gemstones.

Rodeo Flats which is located in the Arizona plains between the Table Mountain and Sycamore Canyon abounds with the most colorful jaspers. The stone can be seen on both sides of Verde River in the area between the Childs power station and the Brown Springs which is a distance of approximately 10 miles.

Jasper is found on the Kohls Ranch which is at an elevation between 5000 and 8000 feet set amongst a pine forest in the Tonto National Forest area in Gila County of Arizona near the town of Payson. Jasper is available as a float in this region over a large area known as the Christopher Creek. The Jasper is of fine grain grade and has gray and white bands and is often referred to as Zebra agate, though it is actually jasper.


Arizona is considered to have one of the most prolific peridot producing sites in the world. Peridot in Arizona is found in the form of tumbled and faceted crystals with colors such as bright green, olive green and yellowish green. While the tumbled peridot is used for making gemstone trees, beads in jewelry and in mosaics, the faceted ones are used in earrings, pendants, rings and bracelets.

The volcanic field of Peridot Mesa which is situated in the San Carlos Apache Indian Reservation of the Gila County of Arizona has a massive deposit of peridot and is known to produce as much as 95 percent of the peridot gemstones in the world. The mesa has a diameter of about three kilometers and is coated with three to six meters thick layer of basalt. The weathering of the basalt layer produces the peridot.

Another locality around the mesa where peridot deposits are found is the canyon and the gullies present just under the mesa which is excavated with the help of bulldozers and sledgehammers. The peridot found in the mesa is granular and is in commercially viable sizes ranging from 6 to 13 millimeters. A few larges samples have also been carved out from the site with a size of around 40 millimeters.

The peridot at the mesa is mined only by the Native Americans from the reservation and is usually marketed in the gemstone industry with the help of local brokers. Those who are large scale miners, sell the product directly in the industry.

Buell Park that lies in Apache County of Arizona at a distance of about 10 miles towards the north of Defiance Fort is another site where peridot deposits are found. The Buell Park consists of a depression with a diameter of about 2 miles and is composed of a volcanic rock cemented with fragments of various minerals known as breccia pipes. This rock and the surrounding soil bordered by the peridot ridge to its southeastern side, hosts the plentiful granular and dispersed peridot among other minerals.

The peridot found here range from 0.5 to 2.5 centimeters across in size and is blemished with colors such as yellowish green to olive green.
