Wan Hao said jade: how to identify the E-goods B cargo C goods

To understand the identification of jadeite should start with Jade's A, B, and C goods. A few years ago, I was often able to hear the business misleading consumers: "A goods are A-class jade, B goods are B-class jade, C goods are C-class jade", even now it can be heard. In fact, A goods, B goods, C goods are completely different concepts.

A goods are natural, without any artificial deliberate treatment of jade, it has a natural color and texture, only A goods jade is what people generally call the real goods.

B goods refers to the emerald after soaking with strong acid, soaked in impurities, and then filled with jade. B goods jade is also called "shine" jade, its texture is fake. The jadeite after strong acid soaking, the dirty impurities are soaked, but at the same time the texture of the jade is completely destroyed, there is no toughness of jade, soft and full of voids, in order to be invisible on the outside, and transparent in the gap Silicone. Therefore, the B-Jadeite looks very beautiful in color, and the texture is very transparent, but its price is very low, often about one-tenth of the same appearance A cargo jade. The reason why many people accidentally buy B goods is that B goods often look good and cheap. However, the B-Jadeite can't stand the test of time. After a few years, the silica gel is oxidized, and the jadeite will become unrecognizable. Someone in the jewelry industry once said that B-Jade is also a real thing. It can only be said that after some treatment, if consumers are willing to buy is the consumer's choice. However, the author disagrees with this view, because the B-Jadeite jade is a raw material that is not enough to make jewelry, and is processed by destructive means to pretend to be high-grade jade, and most buyers are thinking that they can buy real goods (A In the case of the purchase of goods, you can not use this kind of B-car jade that is used to pretend to be high-end genuine goods. The three elements of jewelry are beautiful, durable, rare, and B goods jade does not have these three elements, so B goods jade is not real goods are fake.

C goods are jadeite artificially dyed, artificially added color on the original jade without color, its color is fake, but also fake. There are many kinds of dyeing methods. Most of them are to heat the jadeite first, so that the cracks between the crystal particles are enlarged, and then placed in the dye, so that the color enters the jade along the crack, and the color dyed is mostly green and purple. Yellow, red.

In professional jewelry appraisal institutes, B goods and C goods are easy to be identified, and is there a particularly simple and easy identification method for general laymen? Objectively speaking, the identification of B goods, C goods jade requires many years of identification experience, as a layman, there is no one to use the spirit of the trick. A consultant asked if it was possible to use the hair on the jade to identify the true and false. It is said that this was learned in a jewelry store at a tourist spot. This method is unscientific and there is no scientific basis. Using this method to identify people who suffer from jade will suffer losses.

The simple identification method commonly used by experts is to look at the C-car jade. When looking at the light, look at the distribution of the jade color. It is often seen that the color is distributed along the crack. This color is unnaturally distributed. Much like a capillary, when you see this, you can conclude that the color does not naturally exist in the jade, but enters from the outside. In addition, the dyed color has no color roots, often floating on the surface of the jade, the color is also "dead", "hairpin", without the aura of natural color. Look at the B-car jade, you should turn the jade in the case of looking at the light, find the angle that can clearly see the surface of the jade, and observe carefully that you can see that there are many pits and pitting on the surface of the B, which is the surface of the silica gel weathered. Formed after abrasion and peeling. In addition, the luster of the B-Jadeite is different from the A-carved jade. The A-carved jade structure is dense and the exterior emits a glass luster. The B-car jade is waxy and shiny due to the injection. If it is a jade bracelet, use another jade or coin to tap gently, A cargo jade sound is crisp and sweet, B goods jade sound dull and hoarse, this is also a simple and easy identification method.
