How the turquoise stone is formed
Turquoise is a blue to green matte mineral, a hydrated copper and aluminum phosphate. For thousands of years, turquoise stone has been among precious and decorative stones due to its special color and various properties. This stone was first mined in Sinai and the Egyptians used turquoise stone to make jewelry such as rings, bracelets and earrings.
Over time, turquoise stone became very popular among other countries and in Iran as well. It has many fans because of its healing and spiritual properties. Currently, the turquoise ring has a special place in the world.
How does turquoise stone arise?
This stone is created as a secondary mineral by the penetration of acidic aqueous solutions during weathering and oxidation of pre-existing minerals. For example, copper may be formed from primary copper sulfides such as chalcopyrite or secondary carbonates of malachite or azurite.
Or aluminum can be made from feldspar. Since turquoise stone is usually formed in dry areas, climate variables seem to play an important role in its formation. Inside the igneous rocks, there are phosphorus and AI2O3, and they are removed from the layers of the earth under the pressure of heat, and after these elements reach the surface of the mother rock through the pores, they are mixed with materials in the surrounding environment, such as copper and turquoise stone.
The high color diversity of turquoise also comes from this issue. According to the elements that are absorbed from the surrounding space, turquoise changes its color. The more colorful the presence of copper in the formation of this stone, the more its color tends to blue, and if more iron is involved in the process, the color of turquoise tends to green. Of course, be careful about turquoise stone. It is not created like this in all parts of the world. For example, in China, turquoise stone is created from the acidification of the remains of mammoths, and its color is mainly in the blue spectrum.
In what countries is Turquoise?
The country of Iran
For at least two thousand years, the country of Iran has been the main source of turquoise, and at first the Iranians called it Pirouze, which means success, and then the Arabs called it They called it turquoise, which is also called turquoise in Persian today. Turquoise was used in Iranian architecture to cover the walls of palaces and holy places, because its color was considered a sign of heaven on earth. Currently, the best turquoise in Iran is extracted from Neishabur mines. And the attractive turquoise coloring of this area has caused it to be in great demand from the world market. Meanwhile, the turquoise ring has a special place compared to other turquoise jewelry.
USA
In the USA, there are areas including Arizona, California (Imperial, San Bernardino, Inyo), Colorado (the cities of Conjus, El Paso, Lake, Saguachi), New Mexico (the cities of Santa Fe, Eddy, Grant, Otero) and Nevada (the cities of Esmeralda, Clark, Elko, Eureka) and the cities of Lander have rich turquoise mines. /p>
Egypt
Since **** BC in ancient Egypt and probably before, the Egyptians used turquoise and the Sinai Peninsula is the largest mine in the region. was counted This peninsula has six mines, all of which are located on its southwest coast, and its area is approximately 650 square kilometers.
China
about three For a thousand years or more, China was among the countries with turquoise mines. In addition to China, there are also turquoise deposits in Tibet, the quality of which is superior to Chinese turquoise. Turquoise is not specific to areas with igneous rocks, and it has also been found among shells and sandstones in the Sinai desert and Australia. Sometimes, turquoise is formed due to the effect of surface solutions containing copper on animal bone fossils.
