Identification of jade Although the authenticity and pros and cons of appreciating jade require professional knowledge and experience, the average person can also judge the quality according to the five criteria of color, clarity, transparency, cut and crack. colour: Color has a great influence on the value of jadeite, and the color should be pure, that is, the ratio of primary color to secondary color. In the case of green, pure green is the best, green is yellow or blue, and gray is the worst. In addition, it should be light and light, the darkness of the color is as strong as possible, and it must be clear enough to distribute the color evenly. Cleaness: The less internal impurities, cracks, etc. are better, mainly white and black. It is caused by other minerals contained in jadeite. Relatively speaking, black cockroaches are less white and have lower value. transparency: When the light enters the emerald which is transparent and fine in texture, it will reflect the beautiful light, and the crystal clear and transparent is the high quality. If the transparency is low and the texture is rough, the reflected light will be more dull and its value will be greatly reduced. Cut: Among the various gemstones, Jade is most concerned with the polishing and engraving process, which is divided into two categories: light body and carved. Because the surface of the finished product is not covered, the raw material can not be cracked. The ratio of cutting, the thickness and symmetry of the product are also very important, which is enough to affect the appearance of the jadeite. The carved jade (or "flower") is more aesthetically pleasing and engraved. Usually the jadeite with cracks will be treated in a carved way to cover up the flaws. crack: Cracks can greatly reduce the value of jadeite, because a single collision may crack along the entire crack. Therefore, you must take extra care when purchasing jade ornaments, and you can use the flashlight to check for cracks.
