If the surface of Hetian jade looks like a layer of oil, it looks bright and moist, indicating that this piece of Hetian jade is very good. The measurement of water head is generally described by size. "A little water" usually refers to how deep the light can shine on the jade.

When dividing water, the light transmission depth is 3 mm, and the second division, namely the light transmission depth, is 6 mm. Three-point water, that is, the light penetration depth is 9mm. Basic development: the size of jadeite is not equal to transparency. Among them, three-point water is the best, which means that the jade with a thickness of 9 mm is completely transparent.

Looking at the water content of jadeite, you can directly illuminate the interior of jadeite with a strong flashlight and observe its light transmittance to judge how much water content of jadeite is.

Moisture distribution: It means that the light transmission depth of jadeite reaches 3mm, in other words, we can only see that the surface of jadeite is 3 mm transparent with naked eyes, and then it is "hazy" and translucent. 2. Water separation: It means that the light transmission depth of jadeite reaches 6mm.

When observing the jade head, the average connoisseur will use a spotlight flashlight for lighting observation to see the incident depth of light in the jade. Introduce the depth and you will know how much water there is.

How to treat the head of jadeite original stone?

1. Usually you can observe the transparency of jadeite with a spotlight flashlight, and measure the length of water head with the depth of light. The transparency of jadeite is often described as "one water divides" and "two water divides". Water separation means that minerals with a depth of about 3 mm can be seen.

2. Transparency. Transparent jadeite can clearly see the appearance of objects on the back of jadeite, especially when the sun is clear at noon, jadeite that can penetrate more than10mm in the sun is transparent. Transparent jadeite is generally a high-grade or medium-high-grade commodity.

3, the water head is transparency, depending on the number of impurities in the jade and the depth of the color, which determines the permeability of the jade. The less impurities, the more colorless and transparent, and the longer the water head, such as glass jade; The more impurities, the stronger the color, the lower the transparency and the shorter the water head, such as Gan Qing, Tielongsheng, Cui Mo and Nenmian Jade.

How to identify the planting water of jadeite original stone

1. Distinguish with jade glare lamp: see through luminosity with yellow light. The deeper the light transmittance, the larger the diameter of the surrounding light, indicating that the better the seed water, the more valuable the material.

2. It is to use jade glare to identify the seed water of the original jadeite stone, and turn on the jade glare to adjust the yellow light to see how the light transmittance of the original jadeite stone is. If the transparency is deeper and the diameter of the surrounding light is larger, then it can be explained that the seed water of this jadeite stone is very good and of considerable value.

3. Look at the color: Look at whether the color is pure, rich and uniform, and use a spotlight flashlight to check whether there are hidden variegated colors. Rich, pure and uniform color, less impurities. Emerald green has a higher price, followed by red and purple.

4, listen to the sound: the knocking sound is crisp and pleasant. The louder the sound, the better to plant water. Put the gem flashlight on the original stone, even if the aperture is more than one centimeter, even if the water head has passed, the wider the aperture range, which proves that the water head of this jadeite original stone is better.

How to tell the water content of jadeite?

1, primary water diversion, light penetration depth of 3 mm, secondary water diversion, that is, light penetration depth of 6 mm. Three-point water, that is, the light penetration depth is 9mm. Basic development: the size of jadeite is not equal to transparency. Among them, three-point water is the best, which means that the jade with a thickness of 9 mm is completely transparent.

2. Moisture distribution: It means that the light transmission depth of jadeite reaches 3mm ... In other words, we can only see with the naked eye that the surface of jadeite is 3 mm transparent, and then it is "hazy" and translucent. 2. Water separation: It means that the light transmission depth of jadeite reaches 6mm.

3. When observing the water head of jadeite, the general appreciator will use a spotlight flashlight for lighting observation to see the incident depth of light in jadeite. Introduce the depth and you will know how much water there is.

4. If the surface of Hetian jade looks like a layer of oil and looks shiny, it means that this piece of Hetian jade is very good. The measurement of water head is generally described by size. "A little water" usually refers to how deep the light can shine on the jade.

5, water separation: the light penetration depth is 3 mm-6 mm When the jade is placed on a piece of paper with handwriting, the handwriting below can't be seen clearly through the jade. Secondary water separation: the light transmission depth is between 6 mm and 9 mm. Put the jade on a piece of paper with handwriting, and you can see the vague handwriting below through the jade.

6. The seed water of jadeite can be identified by transparency and texture. The type of jadeite refers to the thickness and compactness of crystal particles, and water refers to transparency.
