1, vertical irradiation: vertically irradiate the jade bracelet with a flashlight, and the size of the inner halo of the jade is the head of the jade. Halo classification: Emerald with a halo of 3mm is called water diversion, and a halo of 6mm means water diversion. Permeability: At the same time, the head of jadeite also refers to transparency. Observe the permeability of jadeite carefully.

2. Usually, the method of inspecting the head of jadeite is to divide water if the light can penetrate the jade material to a thickness or depth of one centimeter. The dichotomy of water means that light can penetrate jade about 2 cm, and so on.

3, particles; The quality of jade head can be observed by observing surface particles, and the surface of jade can be observed with a magnifying glass. The surface particles of jadeite with good water head are very fine and almost invisible, while those with poor water head are rough and obvious to the naked eye.

4. The water head of jadeite refers to transparency and color sense, which is called "water head" in the industry. If the transparency is high and the water head is better, you can put the jade in the sun, or use a flashlight to observe the size of the refraction halo on the surface. Emerald with good water head looks like a shining halo.

5. Use a sun hat to block the sun, and then observe how much light penetrates into the jade to judge the water head of the jade. The water head of jadeite refers to the transmission range of light in jadeite, and the transparency of jadeite is generally called water head in the industry. Long water head and sufficient water head mean good transparency.

How to treat the jade head?

Look at the head of jade to observe transparency. The higher the transparency, the more abundant the water head of jadeite. In other words, it is "short water head" and poor transparency. Jade is clear and pure, delicate and charming, which makes it look good.

Usually, you can observe the transparency of jadeite with a spotlight flashlight, and measure the length of water head with the depth of light. "One water separation" and "two water separation" are often used to describe the transparency of jadeite. Water separation means that minerals with a depth of about 3 mm can be seen.

Looking at the head of the jade bracelet, we can observe the light transmittance of jade under the midday sun.

What do you think of Emerald's head?

Vertical irradiation: irradiate the jade bracelet vertically with a flashlight, and the size of the halo inside the jade is the head of the jade. Halo classification: Emerald with a halo of 3mm is called water diversion, and a halo of 6mm means water diversion. Permeability: At the same time, the head of jadeite also refers to transparency. Observe the permeability of jadeite carefully.

Look at the head of the jade bracelet and shine it vertically with a flashlight, and then observe the size of the halo, which represents the head of the jade. For example, when the halo is 3 mm, jadeite has some water. When the halo is 6mm, jadeite has two kinds of water.

The water head of jadeite refers to the transmission range of light in jadeite, and the transparency of jadeite is generally called water head in the industry. Long water head and sufficient water head mean good transparency. On the other hand, poor water head and short water head mean poor transparency.

The head of jadeite refers to transparency and color sense, which is called "head" in the industry. If the transparency is high and the water head is better, you can put the jade in the sun, or observe the size of the reflection halo on the surface with a flashlight. Emerald with good water head looks like a shining halo.

Look at the structure of minerals. The head of a jade bracelet is related to the structure of minerals. Jade bracelet is a collection of minerals, mainly jadeite minerals. The head of a jade bracelet depends on the type, structure and thickness of jade minerals.

Particles; The quality of jade head can be observed by observing surface particles, and the surface of jade can be observed with a magnifying glass. The surface particles of jadeite with good water head are very fine and almost invisible, while those with poor water head are rough and obvious to the naked eye.
