When buying jadeite online, how can you distinguish cracks, lines or cotton from photos?

With the development of the Internet, knowledge about jade has gradually become popularized, and the mystery of jade has gradually been revealed.

The cracks, lines and cotton in jadeite, which were difficult to distinguish in the past, can now be distinguished by many jade lovers with their eyes and touch.

But new problems have arisen. Now many jade lovers choose to buy jade online. The lines, cracks and cotton that could be distinguished when handling it before have now become blurry when they have to distinguish through photos.

Today I will talk to you about how to distinguish the cracks, lines and cotton in jade through photos.

First, let's look at the cracks

The cracks in jade refer to the cracks formed during the mining and processing due to vibration, impact, etc. They are generally deep, long and straight, and the color is different from the surrounding jade.

Cracks have a great impact on jadeite. In stone gambling, there is an item that specifically bets on cracks.

The jadeite rough stone with good quality, water color and cracks on the surface, the gamble is whether the cracks go deep into the jadeite. If the crack is deep and destroys the material, no matter what the quality and color of the jade is, it will be worthless if it cannot be made into merchandise.

However, cracks on finished jade products, no matter how small, will reduce the value of jade.

Cracks can be divided into epidermal cracks, through cracks, and hairline cracks according to their size, depth, etc.

The degree of damage caused by these types of cracks to jade is different.

Here is a detailed explanation through photos:

The so-called surface crack means that the crack is on the surface of the jade, which is very shallow and does not go deep into the jade.

However, due to the existence of cracks on the surface, there is a high possibility that miscellaneous colors will penetrate into it, affecting the overall beauty of the jade. However, because the cracks are shallow, they do not affect the firmness of the jade and have little impact on the value of the jade.

The so-called through crack means that the crack has penetrated the surface of the jade. This type of crack looks very long and may also be intermittent and very deep.

Many of the cracks that we can usually feel with our fingernails are this type of through-cracks.

This kind of crack has a great impact on the beauty of jade, and seriously affects the firmness of jade. It may break with the slightest touch.

Jadeite with this kind of through cracks is considered a defective product and is not recommended for purchase by jade lovers.

Different from the previous two types of cracks, this type of crack is usually internal and is a crack formed during the formation process of jade, but is filled with other debris later.

This type of crack is visible to the naked eye and has obvious color variation, but it is generally not possible to remove it.

Jadeite with cracks can be divided into minor and severe ones: minor cracks affect the appearance but not the durability, so they can be purchased; severe large cracks should not be considered.

Second, let’s look at the patterns

Lines are one of the most common flaws in jade. In the jade industry, there is even a saying that nine out of ten jades have lines.

The so-called lines are generally divided into two types:

One is the lines that appear during the formation of jadeite, which are mostly in the form of thin lines and appear inside the jadeite, and in a few cases appear on the surface;

The other is that the jade is squeezed by external forces during the formation process, resulting in cracks. However, as the jade continues to be produced, after many years, the cracks are filled and healed by other minerals, leaving only a faint scar. This is the stone pattern.

It should be noted here that some stone patterns are very fine and even difficult to see with the naked eye, and have no effect on jadeite;

However, some stone patterns appear densely, which is more obvious and affects the beauty and value of jadeite.

Here is how to distinguish the lines and cracks of jadeite through photos:

Because looking at a photo is different from handling it in person. With your hand, you can just scratch it with your fingernail, but when looking at a photo, you need to pay attention to the rough edges of the grain. The grain has rough edges, which are very obvious under the light and do not affect the transmission of light. Cracks, on the other hand, are a straight line with no rough edges, which block the light.

In fact, there is a very simple method, which is to directly ask the merchant whether there are wrinkles or cracks. After all, most merchants will still abide by industry rules and will not make random comments about whether there are wrinkles or cracks.

Of course, no matter what, when you buy jadeite online, it must be returnable and exchangeable.

3. Finally, look at the cotton

In fact, in San Ge’s opinion, cotton and cracks are different. There are many jades without cracks, but jades without cotton are basically invisible.

Therefore, cotton is a characteristic of jadeite. It is not a question of whether there is cotton or not, but a question of how much cotton there is or how big or small the cotton is.

“There is no jade without cotton.” Cotton is the characteristic of jade and it is also a standard for determining whether jade is natural.

To the naked eye, cotton is mostly white impurities, mostly white cotton.

Such large pieces of cotton generally appear in jadeite of tender and coarse texture. Such large pieces of cotton will affect the texture of jadeite and is a major flaw.

The cotton is gathered together and looks like clumps. You need to look at this kind of cotton specifically. Whether it affects the appearance depends on personal preference.

This is caused by too many and too dense cotton balls, which make it look dry and ugly, affecting the value of the jade.

This kind of cotton is somewhat similar to texture, but it is uneven and not as neat as cotton.

There is no need to say much about snowflake cotton. This kind of cotton not only does not affect the value of jade, but on the contrary, it greatly increases the value of jade because it forms a unique beauty.

There is a saying that too much is as bad as too little, which is exactly what this kind of cotton is about. This kind of cotton is an upgraded version of snowflake cotton. If the snow is too heavy and the cotton points are too dense, it will cause a snow disaster.

Do not buy this kind of cotton as snowflake cotton. In fact, if you feel it most intuitively, you will find that you cannot see the beauty of it.
