When did the mining of ancient huanglongyu first appear

8000 years ago.

Huanglong jade ancient symbol of power of the stone, jade carved into the dragon and phoenix mostly, which echoes its noble symbol, now the Huanglong jade rough trend continues to rise, has become the object of many collectors. In today's rapid social and economic development, everyone's demand for spiritual living standards is increasing day by day, and the high-quality resources in traditional jade have been depleted. Many factors provide broad prospects for the development of Huanglongyu.

Huanglongyu rough stone ** continues to rise, but at this time, some people can't help but have doubts about Huanglongyu, how much should its value be positioned? Others say that its main chemical ingredient is silica, which is not as valuable as glass. Don't dare or disdain to touch it, but what is the truth?

Huanglongyu rough stone **** is because of its beauty, rarity, durability of the three elements: rather than simply by the composition to determine its quality and value, such as jadeite composition for sodium aluminosilicate, Hetian jade composition for calcium magnesium silicate, and silicate is the main component of the earth's crust, can be seen everywhere. At the beginning, the ancients did not know what their composition was when they discovered, used and collected jadeite and Hetian jade, but because they had the three major elements of excellent jade to be liked and collected, even if today's society can identify their composition by means of science and technology, it cannot be said that sodium aluminosilicate is jadeite, but must be gem-level to be called jadeite, even if it can be called jadeite, there is a low price and priceless difference.

For example, the most precious diamonds have the same chemical composition as carbon molecules, the expensive red sapphires have the same chemical composition as aluminum oxide, and ruby sapphires can be synthetic, but they are still the most precious gemstones. Opal, which also uses silica as the main ingredient, is one of the five outstanding precious gemstones recognized in the world, and it is worth a lot of money, among which the top black Opal has even surpassed the top diamond. Huanglongyu has important elements such as beauty, rarity, and durability, so it is widely loved and collected by people, and there is a reason that the Huanglongyu rough stone will be greatly improved.

Huanglong jade rough stone **** is because it has a rich cultural heritage: because it has only been around for ten years, it denies its value. Chinese jade culture should have a history of about 8,000 years, so the history of the real use of jade by Chinese people should be more than 10,000 years, and the cultural heritage of Huanglongyu lies in its inheritance, development, and greatly enriched and enriched the connotation of China's 10,000-year-old jade culture.

Now in the prosperous era, the 10,000-year-old dream of the Chinese people has been fulfilled, and the saying has been verified: "The prosperous era is prosperous, and the beautiful jade is out."

During the Xia and Shang periods, there was a custom of using jade for sacrifices.

The origin of Huanglongyu is mainly in Xiaoheisheng, Longjiang Township and Zhen'an Township, and the quality and quality of Huanglongyu from different origins are different, but they all have the jade characteristics of Huanglongyu, and it is the only domestic jewelry of high-end jewelry and jade in China.

The main feature of Huanglong jade in Longjiang Township is its large size, which has the potential to be suitable for making large-scale jade carvings and is easy to shape. Moreover, the Huanglong jade in Longjiang Township has good texture, few defects and cracks, fine internal impurities, and is not obviously affected by the external environment. Huanglongyu in Zhen'an Township is mostly used for ornamentation, because the Huanglongyu in this origin has a variety of colors but is not showy, with red, orange, white, yellow, and various colors.

The seed quality of Huanglongyu in Zhen'an Township is higher than that of other origins, and the color is dark, which is conducive to processing as ornamental ornaments and is not easy to get dirty. The most important thing is that the surface of Huanglongyu in Zhen'an Township has patterns, the texture is clear, and it can be carved into a variety of ornamental shapes, and the color is multi-layered.

Maintenance

The main methods of daily maintenance are similar to those of jadeite and Hetian jade:

1. Do not touch hard, so that Huanglongyu is damaged.

2. It is important to avoid high temperature exposure, so as not to lose water and luster of Huanglongyu.

3. Wear and wipe frequently. Wash with a soft cloth or a soft brush soaked in water to remove dirt.

4. It cannot be in contact with acids, alkalis and organic solvents, and these chemical reagents will have a corrosive effect on the surface of Huanglongyu.

Human raising: All high-end fine jewelry of Huanglongyu, because of its warm and delicate texture, do not need to rub oil and wax. As long as you play and touch it often, you can get the long-term moisturization of human sweat and fat and become more crystal clear and watery, and the more often you wear it, the more warm and charming it will be.

Oil nourishment: a widely used method, but must be used for colorless, odorless, clear as water quality baby oil; Pay attention to the observation during oil rearing, and continue to extend the oil rearing time if necessary.

Huanglongyu is essentially chalcedony, and ordinary jewelry ranges from tens to hundreds of yuan.

Huanglongyu has good hardness, high permeability, and bright and rich colors. Because it is produced in Longling, and yellow is the main color, it was finally named Huanglongyu. At present, from the perspective of appreciation, it can be divided into two types: "original Huanglong jade" and "carved Huanglong jade".

In traditional Chinese culture, "yellow is like gold, red is like blood, white is like ice, and black is like ink", and yellow is the most noble and mysterious color in Chinese culture, and is exclusively used by the royal family and religion.

Maintenance Method:

Because pure natural chalcedony has heat dissipation and is easy to lose water, it is not easy to lose water if it is often worn, and it does not need to be soaked in water often, and the more you wear it, the more ice it will become; However, in autumn and winter, when the weather in the north is dry and it is relatively rare to wear, it is best to soak in water regularly for 1-2 days (the colder the water, the better), and it will soon return to its original luster and moisture.

But there is one thing to pay special attention to: before taking a hot bath or soaking in the hot spring, be sure to take it off; Because chalcedony is super sensitive to heat and does not tolerate high temperatures, if you take a hot bath for a few days in a row, or often work in an environment close to fire at high temperatures, the chalcedony pendant will dry out and become less transparent due to water loss.

It is a kind of jade material produced in Longling County, Baoshan, Yunnan. Red, yellow, white and black are several colors, buy the right one, it's okay, but you can't buy the right cotton. When buying, it is best to know first or have acquaintances before buying. Otherwise, you will definitely lose.
