If someone doesn’t know black jade, they would probably think it is just a piece of black stone with an ordinary appearance. Why is it so popular? Only when you look at black jade through the light can you feel its low-key and mysterious charm. Therefore, it is called "the shadow of a lover" or "the shadow of a successful man" and has become a symbol of status and identity. It has become very popular in recent years. The main mineral component of black jadeite is omphacite, which contains a small amount of albite, tremolite and other minerals. It has a fine structure and is less brittle. It is colorless to gray-green or bluish-green. Its deep color is caused by excess Cr and Fe. Black jadeite is jade that appears black due to the excessive richness of green. Black jade is a type of jade, and naturally, like other jades, it has different qualities. So how do you identify the quality of black jade? Since it is jade, the quality of jade depends on the type, water and color. Let's take a look at it below: Texture: The surface of black jade is pitch black. You cannot tell the difference if you look at it this way. Black jade must be observed under strong light. If the texture of black jade is uniform and fine, with no granularity, and no dots, lumps, or web-like cotton wool, then it is high-quality jade. On the contrary, if the grains are rough and uneven, with dots, lumps, or web-like cotton wool, then it is of poor quality. Water head : The size of jade crystal particles and the compactness of its structure determine the transparency of jade, which is the water head of jade. The water head of black jade also needs to be considered, that is, its transparency. Jade with high transparency can transmit light under strong light, and the more transparent the better, and the black jade will also look relatively lustrous and bright. Jade with poor transparency may even be opaque and strong light cannot transmit through it. Color : At first glance, black jade appears to be pitch black, and the color seems indistinguishable, but in fact, even if it is black, there are different degrees of black. When observed under natural light, the color of the surface of the black jade should be as dark as possible. Under strong light, it should appear dark green or dark blue-green, and the color should be evenly distributed without white or other colored cotton patches. In recent years, black jadeite has become increasingly popular in the jade market, especially some pendants, hand-held pieces, hanging plaques and inlaid items. Because of their popularity, their prices have also risen accordingly. Excellent quality black jadeite is very expensive, ranging from hundreds of thousands to millions. Black jadeite with weak surface gloss, coarse crystal grains, loose structure, a lot of white cotton or concentrated white cotton, irregular green translucency, too dark or too light color, and obvious flaws are poor quality black jadeite, and the price will not be high, generally around a few hundred to a thousand yuan. Most of the black jadeite on the market is of medium quality, and the price ranges from several thousand to tens of thousands of yuan.
