Hetian Hongyu is extremely precious. People have such a saying according to the quality of jade: one red, two yellow, three inks and four sheep fat, with red jade as the first, thus showing the high quality of red jade. In ancient times, red jade was also known as red jade. Because of its rareness, it has always been collected only by the royal family. There are few folks, so it is not expensive to have a red jade. It is precisely because of the scarcity of ruby, many people have seen it in the book, only knowing its name and not knowing what it is. So some people doubt that there is no such thing as Hetian Hongyu? Those who disagreed believe that there is actually no Hetian Hongyu in history. The so-called ruby ​​is just red agate; but the pros say that the red jade does exist, but because it is too small, it can be seen. There are few, and can not deny its existence. What exactly is the red jade, and how should it be identified? According to the quality difference of ruby, people divide the red jade into four categories: First, the original ruby, the red area is more than 98%, no impurities, and the jade color inside or outside is the same or almost the same. Second, the secondary red jade, the red area is more than 70%, it is invaded by the external iron ions during the formation of jade, the color of the red is deep and shallow inside, which is because it is from the outside to the inside Color, so its red is different inside and outside. Third, red jade, refers to the appearance of red, the jade inside is jade, such as topaz, white jade, ink jade and other jade, which is common in the market. Fourth, red playful jade, this jade refers to other jade surface with a pretty red, and its area is not very large, this jade market is the most common, such as the ingenious treatment of the carving, can have a unique charm.
