Jade is divided into broad sense jade and narrow sense jade. According to national standards, jade in a broad sense is defined as a massive mineral composed of mineral aggregates (such as traditional jadeite jade, hetian jade, agate, turquoise, malachite, quartzite, Ma Laiyu, Xiuyu, dushan jade, etc.). ), and the narrow sense of jade is the established rule of the jewelry and jade industry for many years. Jade and Tianyu are both defined as jade.

Among them, Hetian jade is less hard than jadeite, so it is called nephrite in mineralogy and jadeite in jadeite. Of course, this is relative to these two minerals.

Things with different colors must have different prices. Jiuzi was born in a dragon, but there are differences. That's why. Emerald has hundreds of millions of imperial things, as well as bricks with a few dollars. So it depends on the specific situation! ! !
