Yes, blood jade, although in the traditional sense, blood jade does not refer to a kind of jade, but blood jade is the best of jade.

Blood jade is a precious jade. Jade itself is spiritual. Ancient emperors and princes forced jade into slaves' mouths.

Try every means to let the slave swallow the jade into his throat, choke the entrance when he dies, and let the jade exist in the dense blood vessels in his throat. Moreover, the truly precious blood jade is mostly soaked in the blood of the living. After a long time, it will be stained with blood, and the blood will reach the heart of jade, forming a gorgeous and precious blood jade. This kind of thing often falls on the skull and is the most precious jade plug. Of course, there are also some dignitaries and noble generals who will stuff jade into their throats, buttocks and other places, all in order to ward off evil spirits, be auspicious and ascend to heaven. Blood is aura, and jade has been sealed as a symbol of good luck since ancient times. For example, the ancient emperor's jade seal, jade ruyi, Yu Pei and jade clothes with golden carvings all represent auspiciousness and power, but blood jade is mainly human blood. Later, some people used dog blood, and resentment condensed in dog blood jade, which was not good for the wearer. Later, some people called it' evil blood jade'. "

In fact, a lot of blood jade is artificially processed now, and of course, there are some precious blood jade, such as the fine Xinjiang white jade, with wisps of blood on it, which is put in the skin or throat of the slaughtered or killed lamb, so that the blood can penetrate into the jade and be taken out a few years later, which is still relatively rare in the world and difficult to buy.
