Turquoise identification method

Turquoise is a very expensive type of opaque gemstone, with a beautiful blue color due to the presence of copper and a green and yellow part. Turquoise is the birthstone of December, a symbol of peace and happiness. The color is dark blue, the pores are small, the density is high, the color is uniform, and the turquoise with few iron wires is high in price and difficult to find. In recent years, turquoise, especially the turquoise with bright blue, has become more and more popular among the majority of Tibetans. In 2012 alone, the average price of turquoise rose by 10%, and the price of quality turquoise rose by more than 50%. The three flaws of fake turquoise make it easy for you to identify turquoise.

How does turquoise make a fake?

Turquoise fraud and optimization treatment did not occur in recent years. Because the turquoise contains water and has pores, it will be light and faint due to water loss when it is excavated from the mine. It usually turns into light green. Or dark gray green. At this time, wiping the green pine with a damp cloth can temporarily restore the bright color. Many high-quality green pines are also optimized by some of the surface to stabilize the turquoise color. Some stability is necessary and is recognized by the international industry.

Some turquoise imitations and Indian fake jewellery work rough and cheap, but repairs are very difficult, even impossible.

The optimization process becomes brighter:

The artificial treatment of turquoise is divided into two methods of injection molding and wax injection, in order to make the turquoise look more vivid and make the structure more dense. According to the previous national standard, both methods are considered “handling” and must be clearly stated at the time of sale; the newly revised national standard identifies wax as “optimized”, which equates to the recognition of the process and does not need to be explicitly stated at the time of sale. Teacher He reminded the vast number of Tibetan friends that there is a large amount of glued turquoise on the market. If it is distinguished by the naked eye, the color of the gauze that has been glued is dull, and the iron wire is also unnatural; if it is detected by infrared detection equipment, the structure can be seen. Internal organic rubber peaks.

Magnesite imitation is hard to tell:

Turquoise counterfeit products currently on the market are mainly falsified with magnesite. Magnesite is mainly produced in Inner Mongolia and is a white stone. Some commercial households apply glue and dyeing methods to treat them. Such a product, if it can be clearly expressed as "Imitated Turquoise" at the time of sale, is nothing but can be sold as a general handicraft; but the cost of magnesite is very low, for example, the hand string is only a few dollars, so some Unscrupulous traders do not expressly sell at the time of sale, in the name of turquoise, in order to make huge profits. According to Mr. He, the turquoise of magnesite is more realistic and difficult to distinguish by the naked eye, but it can still be distinguished by infrared detection equipment.

Any chemical method used to change the composition or structure of a substance or to synthesize a new substance belongs to chemical production technology, that is, chemical technology. The resulting product is called a chemical or chemical product.Chemicals, pesticides, chemical reagents, dyes, etc. are chemical products.
