The four famous jades are the four famous jades in China, which refer to the "Hetian jade" in Xinjiang, the "Lantian jade" in Xi'an, Shaanxi, the "Dushan jade" in Nanyang, Henan, and the "Xiuyu" in Xiuyan, Liaoning.

1. Xinjiang's "Hetian Jade".

The color of Hetian jade is very rich, including white, cyan, gray, light to dark green, yellow to brown, ink, etc. While the main constituent mineral of Hetian jade is white tremolite, Hetian jade is white.

Due to the presence of Mg in the chemical composition of Hetian jade, with the substitution of Mg in the tremolite molecule by Fe, Hetian jade can show different shades of green, and the higher the Fe content, the darker the green of Hetian jade. When the tremolite in Hetian jade contains fine graphite, it becomes black jade.

2. "Lantian Jade" in Xi'an, Shaanxi

Lantian jade reserves are abundant, according to the Shaanxi Provincial Bureau of Geology, the reserves are about 11 million cubic meters, and the types of jade are mainly divided into six categories: white jade, black jade, topaz, green jade, green jade and red jade.

In 2004, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China implemented the protection of the origin of Lantian jade, Lantian County successfully held two sessions of the "Food and Jade Festival", and in 2011, the first Lantian jade processing skills and creativity competition in Shaanxi Province was held, these activities not only expanded the scale of Lantian jade industry, improved the level of processing technology, but also further improved the influence and popularity of Lantian jade.

3. The "Dushan Jade" in Nanyang, Henan

Dushan Jade gets its name because it is mainly produced in Dushan, Nanyang. Dushan is located in the northeast of Nanyang City. Dushan jade jade is tough and micro-dense, delicate and soft, the color is mottled and lush, warm and moist, there are six kinds of pigments of green, blue, yellow, purple, red and white, 77 color types, it is an important jade raw material for arts and crafts carvings, it has become a famous specialty of Nanyang, and it is one of the four famous jade in China.

4. The "Xiuyu" of Xiuyan, Liaoning

Xiuyan jade has complex material composition, physical properties, arts and crafts characteristics, etc., so it is not a single jade species. According to the different mineral compositions, Xiuyan jade can be divided into three types: serpentine jade, tremolite jade, serpentine jade and tremolite jade, among which serpentine jade is the main one. According to the infrared absorption spectrum curve, the composition of serpentine jade is displayed, and it contains a small amount of fiber serpentine and gum serpentine.

Tremolite is mainly composed of tremolite and chlorite jade is mainly composed of chlorite. Through microscopy, transmission electron microscopy, X-ray diffraction analysis, differential thermal analysis and other means, Xiuyan jade can also be divided into three types: serpentine jade, flower color jade, and chlorite jade.

The four famous jades are Hetian jade, Dushan jade, Lantian jade, and Xiuyu.

The four famous jades in China refer to the "Hetian Jade" in Xinjiang, the "Dushan Jade" in Nanyang, Henan, the "Lantian Jade" in Xi'an, Shaanxi, and the "Xiuyu" in Xiuyan, Liaoning. This is the ancestors through comparison, screening, elimination, and finally determined the lofty status of Hetian jade, Xiuyan jade, Dushan jade and Lantian jade as the four famous jades in China.

Its origin is relatively single, after thousands of years of long-term mining and the stock is gradually decreasing, and high-quality Hetian jade is more difficult to mine, so both commercial value and cultural value remain high, and continue to soar.

Hetian jade structure.

The structure of Hetian jade refers to the interrelationship and coordination of the size, shape and space of the mineral aggregates it is composed of. For the structure of Hetian jade, in ancient times, it was called "dense to chestnut", which is the same as the modern "dense consistency", and the structure of Hetian jade can be divided into two categories:

1) Block structure: the most common structure of Hetian jade, Hetian jade is a dense block, the structure is uniform, and the Hetian jade with this structure has a felt-like microscopic interwoven structure, a fibrous metacrystalline structure and a flake metacrystalline structure.

2) Flake structure: Hetian jade is flaked, which is formed by later tectonic stress, and most of the jade with this structure cannot be used.

China's four major jade refers to Hetian jade, Lantian jade, Dushan jade, Xiuyan jade, Hetian jade is mainly tremolite, actinolite, Lantian jade appearance is yellow, light green, Dushan jade jade is tough and dense, Xiuyan jade is warm and delicate.

1. Hetian jade.

2. Lantian jade.

Lantian jade is yellow and light green in appearance, and its jade is opaque, which belongs to the serpentinized diopside, showing glass luster and grease luster, and its jade quality is slightly transparent to translucent. Its origin is Yuchuan Town, Lantian County.

3. Dushan jade.

Dushan jade, also known as Nanyang jade, is produced in Dushan in the north of Nanyang City, its jade quality is tough and dense, delicate and soft, luster and transparent, and its colors are green, white, yellow, purple, red, white, etc.

4. Xiuyan jade.

"Hetian jade", "Lantian jade", "Dushan jade" and "Xiuyu".

The four famous jades in China refer to the Hetian jade produced in Xinjiang, Xiuyu produced in Xiuyan County, Liaoning, Dushan jade produced in Nanyang, Henan, and turquoise produced in Yunxian County, Hubei.

Hotan jade is named after the abundance of Hotan in the southern Xinjiang region, which was called "Khotan" in ancient times, and in Tibetan, it means "the place where jade is produced".

Hetian jade is translucent, polished with grease luster, and the hardness is between degrees.

Lantian jade, one of the earliest jade species developed and utilized in China, has a history of more than 5,000 years, and was mined and utilized as early as the Neolithic Age.
