What does jadeite think of water head?

The world says that women are made of water.

A gentle woman, with endless elegance and charm, has a unique beauty.

Similarly, whether for women or men, the maintenance of body and mind is inseparable from the nourishment of boiling water.

For jade, water is also very important!

1. What is the "head" of jadeite?

"Water", also known as "water head", refers to the size of the light transmission range in jadeite. Generally speaking, it refers to the hydration degree of jadeite, which is a combination of transparency, type and foundation.

Green contains water, so it is quiet and elastic, and seems endless. Colorless water is as clear as a stream.

The transparency of jadeite depends on the internal crystal structure. If the crystal inside jadeite is fine and uniform in size, such a structure can allow light to pass through smoothly, thus forming better transparency, so it can be said to be "good head". However, if the crystals are thick and uneven in size, making it difficult for light to penetrate, the water quality of jadeite is poor.

What do you think of Emerald's head?

Lighting with a flashlight is the most direct way, and you can directly see the depth of light entering jade.

The more light comes in, we will say, "the light is long and the water head is good." The light enters: "the lighting water is short and the head is poor."

But the light should not be too strong, otherwise it is easy to make mistakes and watch the "head" for too long.

Second, what does "a little water" mean?

People in the industry often say: "the difference between one water and another may be twice or even several times worse", and even a little exaggerated "one water covers three ugliness".

So, what does a little water mean? The industry uses the depth of light transmission to measure the "water head" of jadeite, which is called "a little water".

After water separation, the light transmission depth is about 3 mm, and the light transmission depth of two-way water and three-way water is about 6 mm and 9 mm.

Compared with the traditional transparency description, the three-part water is transparent; Water is translucent; Semi-water is slightly transparent.

Like the following, the light can only enter about 1 mm, and everyone can give it zero, calling it anhydrous or dry water, which has low appreciation value and collection value.

Generally, jadeite that can achieve secondary water separation looks very bright and belongs to the first-class product; It is very precious and rare to reach three points of water.

Third, what will affect the "water head"

1. Mineral structure

Jadeite is a mineral aggregate, mainly composed of jadeite minerals, and its head is determined by the type, structure and thickness of the minerals that make up jadeite.

The more uniform the mineral composition, the finer the particles, the less obvious the boundary between particles (so-called "species"), the better the transparency and the better the water head.

Therefore, "planting" and "water" are actually complementary, and knowledgeable people generally say "planting water" together.

2. The depth of color

If the color of jadeite is too dark, it will also reduce the transparency.

For example, full green jade, full color will have a little impact on the water head, but it will not affect the value. Everyone should be flexible!

3. Thickness of jade material

Transparency is related to the thickness of jadeite itself. With the increase of thickness, it is more difficult for light to penetrate jadeite, and the absorption of light by jadeite will also increase, so the transparency will decrease visually.

It looks opaque to the naked eye, but the head is still quite enough when polished.

When processing jadeite, some jadeites with good water head are called trapped water because the slices are too thick and opaque, as shown above, the Yulong brand with the thickness of11mm.

Third brother: Cui friends must also pay attention to the fact that the value of jade is not only "water", but also comprehensively consider various factors such as species, color, bottom and work!
