Although the head of jadeite can't be simply summarized as transparency, its concrete performance must be reflected in transparency. In the line, according to the distance that the light can pass inside the jade when illuminated by a spotlight flashlight, it is generally divided into one to three points.

The water head is transparent. It depends on the amount of impurities in jadeite and the depth of color, which determine the permeability of jadeite. 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.

The size of jadeite original stone refers to the synthesis of jadeite texture, transparency and purity. Emeralds are made of crystals. The finer the crystal particles, the more orderly the arrangement between crystals, the denser the structure, the higher the transparency, the better the cleanliness, and the stronger the visual effect of water texture. This is the head.

Look at the depth of the color, the water head of the jade bracelet will also be related to the color depth of the jade bracelet. Generally speaking, if the color of the bracelet is dark, the head of the bracelet will also decrease, so the head of the jade bracelet is generally green.

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.

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 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.

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.

Usually, the method of examining the head of jadeite is to divide the water if the light can penetrate through 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.

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.

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.

Shang Hui Futures Commission

It is normal for futures companies to charge fees. How many times a day depends on the number of transactions of users, and the transaction fee is calculated according to the number of transactions. There are more than 100 regular futures companies in China, as long as they can be found through official website of CSRC, they are all regular.

Usually, the handling fee of Shang Hui futures will be adjusted according to the margin ratio stipulated by the exchange. The handling fee rate of iron ore futures is 0.6%, namely 1 hand 8 yuan. The primary price of Huizhou merchants' futures products ranges from several yuan to several hundred yuan, depending on the publicity of Huizhou merchants' futures.

Right, it's not high, because he ranks lower in the futures company, and theoretically, the lower the handling fee.

Calculation formula The income of futures intermediaries comes from the handling fees generated by customers' transactions, which can be expressed by the following formula: the income of futures intermediaries = the transaction amount of intermediaries' customers x the transaction fees x the commission rebate ratio of intermediaries.

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.

Look at the shades of color. The water head of the jade bracelet is good, depending on the color of the jade bracelet. If the color of the jade bracelet is too dark, it will also reduce the transparency of the jade bracelet. The full color of green jade bracelet will slightly affect the water head, but it will not affect the value of jade bracelet.

In fact, if the water head is an expert, it mostly refers to the transparency of jade. In the case of high transparency, experts will call it a long head, and vice versa, it will be called a jade with short head and good head, indicating high transparency. In any case, it will be crystal clear, and no matter what color, it will be vivid and smart.

Use a visor to block the sun, and then observe how much light penetrates into the jade to judge whether the water head of the jade is good or bad. 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.
