The color of the jade green jade is green and has a vein-like distribution, which is very irregular; the texture is coarse and translucent. Its background color is light green or other colors. 1 Look at the color: see if the color is pure, rich, even, and use a spotlight flashlight to check if there are hidden mottled colors. It is better for the color to be rich, pure, uniform, and the impurities are small. Emerald green has a higher price, followed by red and purple. In the green, the fresh, slightly yellowish three-water-containing seedling green (also known as "Yangtze" green) is the best, followed by gem green, river green, and oil green, all of which are evenly distributed in green. 2 Observing transparency: Observing under strong light, the higher the transparency, the better. 3 listening to the sound: the knocking sound is crisp and sweet. 4 observe the green and stone flowers: observe the light, there are other mineral particles in the jade (the green), and often have a mass of white flowers, called stone flowers. Both are less good. 5 Look at cracks and dark spots: cracks are found in the original ore, and some are caused by processing, with less is good; black spots are black spots everywhere in the jade, but also small and small is better. 6 look at the processing level: the surface is smooth, polished, and the shape is just right.
