2. Goods B refer to jadeite that has been soaked in strong acid, removed impurities and filled with glue. B Jade is also called "shower" jade, and its texture is fake. After being soaked in strong acid, the jadeite is soaked with dirty impurities, but at the same time, the texture of jadeite is completely destroyed, soft and full of gaps, without the toughness of jadeite. In order to be invisible in appearance, transparent silica gel is added in the gap. Therefore, B jadeite looks beautiful in color and transparent in texture, but the price is very low, which is often about one tenth of A jadeite with the same appearance. The reason why many people accidentally buy B goods is that B goods often look good and cheap. However, B Emerald can't stand the test of time. Generally, after a few years, silica gel is oxidized, and jadeite will become unrecognizable. People in the jewelry industry once said that B jadeite is also genuine, and it can only be said that it has undergone some treatment. If consumers are willing to buy, that's their choice. But I don't agree with this view, because B-grade jadeite is a low-grade raw material that is not enough for jewelry, and it is processed by destructive means to pretend to be high-grade jadeite, and most buyers buy it when they think they have bought the real thing (A-grade jadeite), so it can't be said that B-grade jadeite specially used to pretend to be high-grade genuine jade is the real thing. The three elements of jewelry are beauty, durability and rarity, but B jade does not have these three elements, so B jade is not real but fake.
3, C goods are jadeite artificially dyed and artificially colored on the original colorless jadeite. Its color is fake, fake. There are many ways to dye jadeite. Most of them first heat jadeite to enlarge the gap between crystal particles, and then put some dye into it to make the color enter jadeite along the gap. The dyed colors are mostly green, purple, yellow and red. In a professional jewelry appraisal office, goods B and C are easy to identify, but is there a particularly simple and easy identification method for laymen? Objectively speaking, it takes many years of experience to identify B-goods and C-goods jadeite. As a layman, there are no clever tricks to use. A consultant once asked if it was possible to identify the truth by burning hair on jade. It is said that I learned this in a jewelry store in a tourist attraction. This method is unscientific and has no scientific basis. Using this method to identify jade will make people who buy jade suffer.
Looking at the jadeite of C goods, if you look at the color distribution of jadeite under the light, you can often see that the color is distributed along the cracks, which is unnatural and looks like capillaries. Seeing this situation, we can conclude that the color does not naturally exist in jade, but enters from the outside. In addition, the dyed color has no color root and often floats on the surface of jade, and the color is also "dead" and "dim", without the aura of natural color.
To see the jadeite of B-goods, we should turn it over to find an angle where we can clearly see the reflection on the surface of jadeite. Careful observation shows that there are many potholes on the surface of B goods, which are formed by the weathering, wear and peeling of silica gel on the surface. In addition, the luster of B jadeite is different from that of A jadeite. Jadeite has a compact structure and a glassy appearance. Due to the glue injection, the appearance of B jadeite is waxy luster.
If it is a jade bracelet, tap it gently with other jadeites or coins, and the sound of A jadeite is crisp and pleasant, while that of B jadeite is dull and dumb, which is also a simple and easy identification method.
