Of course, centers and schools related to gemstones must equip themselves with the latest tools and technology in the world in terms of cutting and carving gemstones, to be able to keep pace with international standards in this field
Gemstones have different sources and pressure and temperature are two factors that are involved in their formation. In general, the materials and Minerals that make up the Gemstones are including:
- Magmatic
- Metamorphic
- Sediment
- Organic
So far, about 200 areas including the gemstones have been identified in Iran. Therefore, the development of milling cutters can be job opportunities in the field of exploration, extraction, production, trade, and export. Most of the gemstones identified in Iran are agate, turquoise, crystal, garnet, and jasper. Many of these Gemstone mines are located in Khorasan, Isfahan, East Azerbaijan, Hamedan, and Zanjan.
Although the trade in gemstones is one of the most profitable types of trade, unfortunately, there is no accurate and organized scientific study center in the distribution and exploration of gemstones in Iran.
Iran plays a small role in the gemstone trade. The added value of processed Stones will be about 700 % of the ore, but the industry of carving and cutting gemstones in Iran is not developed. The value of exports of gold, jewels, gemstones in 2004 (compared to the year 2003) is approximately 1.86 percent.
Exports of gold, jewels, and gemstones in 2004 (compared to the year 2003) is reached to the 5.81 percent and reduced to 5.800 kg.
At present, Iran's main exports are handicrafts, carpets, turquoise, and gemstones. Recently, the Iranian Handicrafts Organization has established training workshops in various places such as East Azerbaijan, Ardabil, Markazi, Tehran, West Azerbaijan, Khorasan, Fars, etc. to improve the gemstone cutting industry.
Of course, centers and schools related to gemstones must equip themselves with the latest tools and technology in the world in terms of cutting and carving gemstones, to be able to keep pace with international standards in this field. Iran is located in the world Diamond line, so it should take steps in the development and production of precious and semi-gemstones as much as possible to develop and improve this industry. Iran is dependent on oil export earnings, while precious and semi-gemstones will make the economy more profitable.
Agate is found in abundance in Iran and so far more than fifteen cases of Agate minerals that six cases are economically exploited. Agate deposits in Iran have been found in modern Oligocene volcanic Rocks up to the present day, all of which have precipitated silicon-rich acidic solutions within the cavities.
Thus, amygdala to geodesic shapes is formed on the surface of the earth, which is composed of layers with different colors of agate. Some of them are filled with layers of agate while others have holes in their center. The presence of layering in these structures indicates the periodicity of sedimentation of agate layers, which can be attributed to the alternating periods of activity of hydrothermal solutions.
