For the market, the jade bracelet that is difficult to distinguish is very troublesome for consumers when purchasing. The identification of the jade bracelet is their biggest concern. The identification of the jade bracelet requires the following elements as the basis for judgment: 1. colour The color of the jade is varied and the depth is different. Among them, the green series is the best, followed by the yellow. Evaluation of its color needs to be observed in terms of concentration, purity, vividness and uniformity. Generally speaking, in the concentration of Saitama color, the medium concentration is the best, too deep or too shallow is poor; purity refers to the purity of the color, the color tone is pure, and the color is poor when doping other colors; the vividness is Refers to the brightness of the color, the higher the vividness of the jade, the better. Uniformity refers to the uniformity of the color distribution, and the more uniform the color, the better, except for the jade in the jadeite variety. 2. transparency Transparency is an important factor in identifying the quality of a jade bracelet. One of the distinguishing features of Xiuyan serpentine jade is that the overall transparency is relatively high. Currently, the most common on the market are sub-transparent and translucent jade, which are rarely transparent or slightly transparent, so the transparency is better. The price of jade will be higher. 3. texture The texture of jade is fine and uniform. The size of the jade crystal particles determines the fineness of the jade. It is generally observed with the naked eye. If there is obvious graininess, the jade is coarser. If there is no graininess, the jade is more delicate. In general, the texture of Saitama is mostly delicate, and a few are slightly rough. That is, the finer the texture, the higher the transparency, which can increase the beauty of the jade. 4. Cleaness Clarity refers to the cleanliness inside the gemstone, that is, whether it contains impurities, blemishes, stains, etc. Because of the high transparency of the jasmine, it is easy to judge the clarity of the impurities and cockroaches inside.
