What’s the secret behind the jadeite back cover? It's not too late to know now

With the popularity of inlay, many jade lovers will encounter a problem when buying jade, that is, the bottom cover. They also often hear sellers say that they can open the lid and see cracks, etc. So how important is the bottom cover to jade, and what kind of tricks are hidden behind it?

1. Is the purpose of sealing jadeite to cover up flaws?

There have always been two very extreme views on the backing of jadeite: one, high-end jadeite is not sealed on the backing; the other is that the backing is inlaid to cover up flaws. This means that the jadeite at the bottom is either of poor quality or has defects that need to be concealed.

Why did this view come about?

Of course, this is because some unscrupulous merchants have done this before. They cover up the thin bottom jade with a sealing method, or put the side of the jade with cracks and flaws facing the sealing method, and then sell it at a high price, causing many people to suffer losses. Over time, the sealing method has changed from an ordinary inlay method to a fraud method in people's impression.

But in essence, the jade backing is just a process of inlaying, and it is not deliberately created to cover up defects. If someone uses it to forge jade, that is a human problem, not a bad backing.

In fact, when the back cover is used properly, it can play many positive roles.

2. What is the function of the jadeite backing?

1. Protect jade from collision and wear

Although jade is very hard, it cannot withstand wear and collision, especially high-quality jade. If it gets scratched even a little, you will feel sad for a long time. The back cover can avoid this problem to the greatest extent. Even if it accidentally falls to the ground, it can play a certain cushioning role and reduce the damage to the jade.

2. Keep the bottom of the jade clean

Jade that is exposed to the air for a long time is more susceptible to the adhesion of dust, soot, and oil, and is also difficult to clean. With a backing seal, the frequency and workload of jade cleaning can be greatly reduced.

3. Focusing light to beautify and increase the sense of heaviness

In addition to its practicality, the back cover can also beautify the jade . The back cover can focus the reflection, making the water head of the jade show better, and it looks more transparent and lustrous.

In addition, the presence of the inlaid backing can visually increase the thickness of the jade, making it look heavy and substantial. This beautifying effect is normal and reasonable and does not constitute counterfeiting or deception.

3. Which jadeite is suitable for the back cover?

The backing will make the jade look more beautiful, but not all jade is suitable for backing. Depending on the situation of the jade rough stone, the suitable backing method will also be different.

1. Regarding the color of jadeite

For jadeite with a rich color , since the color will reduce its transparency, you can seal it with a white base to allow light to reflect and make the jadeite look more transparent.

For light-colored jadeite, a yellow base is usually used , which will make the jadeite look more colorful.

For jadeite with unsatisfactory color , the bottom needs to be sealed. This can produce a focusing reaction and make the jadeite look bright in color.

For jadeite with uneven color distribution, it is generally not left suspended in the air when sealing the bottom. However, if the color is evenly distributed, it can be slightly suspended in the air to increase the translucency and thickness.

2. Regarding the quality of jadeite

A netizen said it well, for materials with poor water content, it doesn’t matter whether the bottom is sealed or not. It will only have a bonus effect on jadeite with good water content and increase the sense of jewelry.

For jadeite with poor quality, light cannot penetrate the jade. Even if the light reflection is enhanced by sealing the bottom, it will be of no avail . Jadeite without water may become darker after sealing the bottom, which is worse than having no bottom sealing. In the final analysis, the back cover is just the icing on the cake and cannot turn something bad into something good.

4. What types of back covers are there?

The so-called "bottom sealing" is to wrap the bottom of the jade raw stone with metal material. Nowadays, the common bottom sealing types on the market are lid sealing, full sealing, and mesh sealing .

1. Liftable bottom cover

The lid is also called a window. This type of back cover can be opened, or there will be a small movable lid. After opening it, you can clearly see the inside of the jade, which is convenient for identifying the quality of the jade.

2. Fully sealed

The entire bottom is sealed and there is no way to open it to see. If you encounter this kind of bottom, you need to observe carefully and be careful not to be deceived.

It is mostly used in jade ring inlay, and the bottom of the ring is sealed with a mesh metal. Because it is hollow, you can see part of the interior. However, it is generally impossible to open it without the help of professional tools.

5. What are the materials of the back cover?

The inlaid backing is generally made of metal materials, such as silver, K gold, platinum, pure gold, etc. Different inlaid materials can be selected according to different costs and personal preferences.

Among them, K gold has many advantages such as high hardness, high toughness, not easy to deform and wear, easy recycling, rich and long-lasting colors, and relatively affordable price . It is one of the most commonly used back cover materials.

In addition, silver is relatively cheap, but it turns black easily; platinum has a beautiful color, is resistant to melting and wear, but is expensive; pure gold is too soft and has a low hardness, and cannot play a good fixing role.

Therefore, how to choose suitable materials for inlay is also a great science. Many jade lovers are troubled by it, and sometimes even lament that soy sauce is more expensive than chicken.

6. How should we view the back cover?

The back cover has both advantages and disadvantages. The disadvantage is that some unscrupulous merchants seal the bottom to cover up the defects on the bottom and sell inferior products at high prices. However, many high-quality jadeite will also be inlaid with a bottom for safety reasons and to achieve a good display effect.

Therefore, don’t assume there is something fishy as soon as you see the back cover, but rather judge based on the circumstances. If you are really worried, it is recommended to choose jadeite with a movable bottom that can be opened, so that you can see the true condition of the jadeite from the bottom and avoid being deceived. Of course, if you are setting your own loose stones, you don’t have to worry about these problems, just do whatever looks good~~
