Skills of judging jade quality

The quality of jadeite is generally judged from five aspects: texture, hardness, transparency, specific gravity and color. The texture of jade refers to the delicate and moist degree of jade.

The higher the hardness, the more difficult it is to process and the better the quality of jade. Although the hardness index of jade can be known by detecting its internal crystal structure with instruments, the method of scraping hardness is generally used in operation. The hardness of common jade in China is between 4 and 6 degrees, which is higher than copper and lower than glass. In other words, jade may not be able to carve marks on glass.
