In Iran, for many centuries, this country has been widely used to decorate objects, mosques and many important buildings inside and outside the country. This Iranian method of construction later found its way to the IndiaN subcontinent, and turquoise was used in the construction of the Taj Mahal. And this color was considered a symbol of God’s paradise on earth. Archaeological excavations in Central Asia show that Iranian turquoise has been found in the graves of the wealthy in the region and throughout the Caucasus.
One of the most important archeological finds in northeastern Iran in the Tower Hill area around the historic Neyshabour mine is a 45-year-old skeleton woman who was found with a piece of perforated turquoise stone near the back of the skeleton.
Throughout history, Iranian turquoise-shaped egg-shaped grains have been used to make jewelry and workpieces. It is said that due to the lack of processing technology, this valuable stone is now exported raw from Iranian mines to Turkey and after cutting and processing, it is offered to the world as Turkish turquoise stone, and countries such as China, India and Italy also try to get the business center of this beautiful stone.
Turquoise stone specifications
:
Turquoise mineral of liquid and aluminum phosphate with a distorted crystalline structure, opaque and waxy transparency and hardness of 5-6 degrees on the MOH scale .MOH is a scale for determining the hardness of stones from zero to ten, the hardest of which is a diamond with a hardness of 10.
This rock is formed under the influence of acidic solutions in the aquatic environment and is found in the form of compressed masses or separate streaks inside the rock crevices in the form of round or rubble.
The best climatic conditions for the formation of this rock are dry areas. The gem is usually found in areas where rocks are left over from volcanic activity or global warming has contributed to its formation.
Turquoise is a rock with a porous texture, and the lower the porosity and bubbles inside the stone, the higher the purity, and therefore the harder and stronger it is, and the less likely it is to break or crack for initial extraction or cutting. Due to the many pores in this stone, copper and aniline salts can be used to brighten it.
Turquoise is identified and exploited in different parts of the country, including Neishabour, Baghu (Damghan), Allahabad and Yakh Abad (Kashmar), Midok and Firoozeh wells (Babak city), depending on their quality and economic value. Neishabour Turquoise Mine is the oldest and most important mine in the country and has a special reputation in the world. Neyshabur has long been an important city on the Silk Road, linking the Iranian plateau to Central Asia on the one hand, and the Anatolian Plateau and the Mediterranean coast to China on the other. These mines are located near an old route that used to be a transit point for trade caravans in ancient times.
Turquoise is sometimes difficult to detect in nature. For example, in Iran, variscite stones are very similar to turquoise, but with a relatively green color. Chrys and colla is another mineral that has a similar color but is recognizable due to its lower hardness of 2.5-3.5.
