It is widely favored and sought after by people. Moreover, due to people's yearning and fascination with it, its reputation has spread all over the world. Today, the editor of Jewelry School will share with you some knowledge about jade, including the origin and characteristics of jade:

The origin of jadeite: China is known as the "Jade Kingdom", and jade has accompanied the Chinese nation for at least 7,000 years. Traces of jade appeared as early as the Neolithic Age 7,000 to 8,000 years ago. During the Hongshan Culture, Longshan Culture and Liangzhu Culture periods 4,000 to 5,000 years ago, a large number of exquisite jade artifacts emerged.

The profound jade cultural heritage made jadeite an important rising star in the jade family at the end of Ming Dynasty and the beginning of Qing Dynasty with its dense and tough texture and naturally bright color, and its value has been increasing in the past 200 years of evolution. It goes far beyond China's traditional Wang Shi - tremolite and actinolite nephrite. From the Qing Dynasty to the Republic of China. Jade is basically circulated among the rich and powerful, becoming a symbol of their status and a collection of concentrated wealth. Now, jade has entered the mass market. On the one hand, it satisfies people's love of beautifying life and returning to nature, and on the other hand, it satisfies people's strong desire for wealth.

Characteristics of jade: Jade is an aggregate of various minerals, mainly jadeite. The main component, jadeite, belongs to the monoclinic crystal system. And the shape is columnar. The common structures of jadeite are morphological and granular metamorphic structures. When the crystal particles are coarse, the cleavage planes on the surface of the jade can be seen flashing. Gemology calls it "emerald green". It is worth pointing out that although the jadeite green is an important identification feature of jadeite, it is difficult to see the jadeite green in high-quality jadeite.

Jade comes in a variety of colors. The colors, shapes and combinations are ever-changing. The depth and distribution of colors are different. Sometimes there are even five colors on a piece of material at the same time. Jade has a glassy luster and is translucent to opaque, and rarely transparent. The vast majority of natural jade has no fluorescence, and a few green jades have weak green fluorescence. If the feldspar in white jade is petrified by kaolinite, it will show weak blue fluorescence. However, it is fundamentally different from B-grade jadeite, which shows strong fluorescence due to filling with a large amount of organic glue.
