1. Planting water: The species of jadeite refers to the compactness, fineness and transparency of jadeite structure, which is composed of jadeite, namely aluminosilicate minerals. Most of the crystals that make up jadeite are granular, and some are fibrous. Water head is the title of jade transparency, and the industry often associates species with water, which is collectively called species water. The quality of the species depends on the texture, and it also affects the quality of the water head. Observe the transparency of jadeite with spotlight flashlight, and measure the length of water head with the depth and width of light. The transparency of jadeite is often described as "one water separation" and "two water separation". As for the seed in the spotlight, it mainly depends on its particle size, whether the meat quality is delicate and close, and whether it is just right. Seeing seeds under strong light is mainly to observe the backlight. The stronger the backlight, the older the seed. If you can shine, you can grow waxy ice. The clearer the water, the older the seeds and the more delicate the meat.
Second, jadeite should be viewed under the correct light source. Different light sources observe the color of jadeite, and the results are different. "Jade under the beautiful light in the moonlight", generally speaking, the original jade stone is more beautiful under the light. In fact, the color of jade is the most accurate only when it is seen in the bright sunshine. Color in natural light refers to finished products or bright materials and window materials; Cloudy world will have color difference; Under the irradiation of yellow light, the color of jadeite will be more vivid and the color concentration will increase. So all the lights used in jewelry stores are yellow. Looking at jade under white light is just the opposite, which will look down on the grade of jade. Many people think that if you don't look at the color under the lamp, it is a finished product or a bright material. If you don't gamble with bright light, you may miss many opportunities to make a fortune. For example, if you don't use strong light, you can't see the color in most cases. Pay attention to whether there are colored roots, whether there are inherent colors in pine flowers, and whether there are bumps in python. Under normal circumstances, white fog will be lighter in color under the lamp; If it is exposed or finished, it will deepen, and the color difference is about 20% to 30%. You can only judge cotton, cracks and makeup lights under a flashlight.
3. Fog: The fog of jadeite refers to a semi-oxidized and slightly weathered jadeite between the jadeite skin (weathered or oxidized) and the jadeite interior (not weathered or oxidized) or meat. Its color formation is related to the surrounding environment. It is an exogenous color without color roots, and generally it will be scattered when the light is turned on. The color of internal jadeite is formed by the release of iron and chromium elements in jadeite, with colored heels. The color of flashlight is not easy to disperse when used.
