How to identify jade

At present, the collection and investment of jade are gradually warming up. All the big shopping malls and professional markets in the trading market, as well as the shops with unique stores, there are also a lot of market stalls, which are difficult to distinguish, so many fans can’t help themselves. Now, how to identify the jade entry, briefly describe it.

How to identify jade

In a narrow sense, jade has the distinction of "hard jade" and "soft jade". Jadeite is jade. Jadeite is actually a basic pyroxene mineral, which is often cryptocrystalline, dense, with a pearly glassy luster, chemically stable, transparent or slightly transparent, with colors ranging from green to apple green to white and red. Nephrite is a mixture of tremolite and fibrous microcrystals interwoven into a felt. It is dark green to milky white, transparent or translucent. It is tough and not easily crushed. It has a brilliant waxy luster after honing. Transparent crystal.

In a broad sense, jade includes many minerals and rocks used in art and sculpture, such as Xiuyan jade, jasper, and Qingtian stone. In fact, jade is not mysterious. It is just a special, beautiful mineral and rock.

Therefore, there are two key points in judging the value of a piece of jade.

The key to grasping the characteristics of each jade, such as Russian jade, Afghan jade, Qinghai jade, etc., similar to or similar to Hetian jade, we will analyze it.

The first key is hardness. Sometimes when the buyer and the seller are unable to hold each other, the other party will remind you to put the jade on the glass, iron or other sharps to see if the hardness is hard and hard, and then determine the texture of the jade; The teacher often said that eating a knife without eating a knife is also the reason. If you eat a knife, the jade is soft and the texture is relatively poor. If you don't eat a knife, the hardness is high and the texture is relatively better. What is the reason?

For example, Hetian jade is produced in the Kunlun Mountains. Due to the movement of the earth's crust, it is submerged as the mountain rises and falls. It is alluvial in the river. After millions of years of snow and ice, it is white and moist, and the crystals are tight. This is the seed jade, but still in the mountains, the same jade, but due to the lack of river water, the crystal is soft, this is the mountain jade.

Another key is to look at the moisture of a piece of jade, the finest Hetian seed jade, whether it is in the eyes or in the hand, has a warm feeling, its whiteness is very delicate, very oily, and Glossy, the natural beauty, like the pure nature of winter snow, the thick like fat, the tenderness of a baby, it is so beautiful.

If the above two key conditions are met, it is a good jade. But things in the world can't be easily simplistic. It is also a mountain range. Because of the different heights, positions, and trends of the mines, the jade that is mined will be very different. How do we identify them in the colorful jade family?

Qinghai jade (called Qinghai material on the market) is a mountain range with Hetian jade, but due to many geological environmental factors, it has a certain difference with Hetian jade. The biggest feature of Qinghai Jade is that it is transparent and the color is gray. The water line is often seen in the bulk material. The visual sense after polishing is large, not oily.

Russian jade is Russian jade (called Russian material on the market). Its various indicators are very close to Hetian jade, and the whiteness is slightly better than that of Hetian jade. The difference is only oily. Russian jade is mostly slightly dry.

Afghan jade (referred to as Afghan material on the market): As the jade jade in Afghanistan is very fine and uniform, the luster is lustrous and the jade flower is not visible to the naked eye. It is often used to pretend to be the best white jade or suet jade. The method of identification is very simple, just use The fingernails are scraped hard. If you can scrape a little white skin, it is not white jade.

From the above comparison, we can easily see that Hetian jade is white, hard and oily and moist; Qinghai jade whiteness and oiliness are inferior to Hetian jade; Russian jade whiteness exceeds Hetian jade, but oiliness is poor; Afghan jade whiteness and oiliness are comparable to Hetian jade, but the hardness is poor.

Because the things in the world are not isolated and absolute, when we purchase jade judges, we must not use the same formula to set them. For example, the quality of Qinghai materials also has the excellent characteristics of Hetian jade, as long as it is moist and oily. , density, whiteness are enough, it can also be comparable with Hetian jade. Of course, it is also necessary to identify the use of the general Qinghai jade to fake Hetian jade.

Russian jade is also the same, it should be noted that because the whiteness of Russian jade exceeds that of Hetian jade, it is only relatively poor in oiliness and moisture. Therefore, the high-end goods in the market like sheep fat jade and white jade are mainly Russian jade, and Applying a layer of oil to the surface of Russian jade to make up for its lack of oil to serve as Hetian jade.

Buying jade is a process that requires both a certain basic knowledge and sufficient practice to combine. In order to avoid the risks of collection and investment, the author believes that it is best to go to some large professional shops with credibility and brand. For example, the “Jade World” franchise area of ​​Hangzhou Collectibles Market, Zhejiang Jewelry, Hangdi Jewelry, etc. In addition, it is best to ask some experienced seniors to take the helm of the eyes and to check the balance, not only to maximize the investment benefits, but also to gradually improve the level of appreciation in practice.
