If you want to buy a satisfactory agate jewelry, you need to master certain agate identification knowledge. People's judgment on the quality and economic value of agate is generally based on the naked eye recognition. Although modern science and technology are developed, many jade identification instruments are available. However, it is very inconvenient to use these instruments in the transaction process. Secondly, the problem cannot be solved. The reason is very simple, and it will be limited by the environment. If the quality and economic value of agate are judged, the instrument has no use. It is impossible to perform complex instrumentation at the trading site, so visual identification is always an extremely important method. There are many kinds of agates, which are known as "a thousand kinds of agates and thousands of kinds of jade". Therefore, there are many methods for identification. Usually, the strips, colors, transparency, cracks, impurities, sand core and weight are the grading standards, except for the water agate. Exquisite, generally with a harmonious color of raw materials as the best.
In general, the identification of agate quality and the assessment of economic value are mainly classified as follows:
1, special grade: beautiful stripes; pure color, bright red, blue, purple, pink; good transparency, that is, translucent; no cracks, no sand core, no impurities; block weight of about 5 kg or more.
2, level 1: beautiful stripes; pure color, bright red, blue, purple, pink; good transparency, that is, translucent; no cracks, no sand core, no impurities; block weight about 2-5 kg.
3, two: beautiful stripes; pure color, bright red, blue, purple, pink; good transparency, that is, translucent; no cracks, no sand core, no impurities; block weight of about 0.5-2 kg.
4, three: beautiful stripes; pure color, bright red, blue, purple, pink; good transparency, that is, translucent; no cracks, no sand core, no impurities; block weight of about 0.5 kg or less.
The above aspects are the identification method of the quality of true agate. In addition, China Agate Network brings you how to identify fake agate. The main products are synthetic agate, glass, plastic, stone, etc., although its texture and color The degree is comparable to natural agate, but it is not economical.

4. Weight: True agate jewelry is heavier than synthetic agate jewelry.
5. Temperature: True agate is warm in winter and cool in summer, while synthetic agate changes with the outside temperature. It also becomes hot in the heat of the day, and it cools in the cold.
