Huang Longyu's texture density, fineness, transmittance and softness of reflected light are all important indicators to measure its grade. Huang Longyu has compact structure, fine texture, good light transmission, soft refracted light, and is absolutely first-class. Huang Longyu is a kind of jade. For Huang Longyu's collection, the higher the grade of Shi Yu, the better.

For example, like jadeite, tens of millions of jade bracelets still have huge value-added space in the case of scarce resources. On the contrary, the low-end jade bracelet worth several hundred yuan has only geological significance, no gemological significance, and almost no room for appreciation, and so does Huanglongyu. The quality of jade determines the most important value of a work.

Huang Longyu's related introduction:

Huang Longyu, also known as Dragon and Huanglong Stone. High-quality gem-grade Huang Longyu is mainly produced in Xiaoheishan Nature Reserve in Longling County, Baoshan City, Yunnan Province and the surrounding Supa River Basin. It is close to the origin of jadeite in Myanmar and belongs to the Yunnan-Myanmar gem metallogenic belt formed by the mutual extrusion of Eurasian plate and Indian Ocean plate.

Huang Longyu is a new jade species discovered in Longling, Yunnan in 2004. Its main colors are yellow and red, as well as sheep fat white, blue white, black, gray and green. Known as "yellow as gold, red as blood, Bai Rubing as black as ink". Specifically, yellow is yellow, honey yellow, egg yolk, chicken oil yellow, orange yellow, loquat yellow and other shades of yellow.

Red ones are chicken blood red, cinnabar red, pig liver red, rose red, light red, water red and so on; White has snow white, ice white and so on. On February 20 1 1, Huanglong jade was officially listed in the national jewelry and jade list, becoming a natural jade with the same name as jade and Hetian jade.

Huang Longyu is a kind of stone with great collection and investment value. In Huang Longyu, there are collections of stone carvings and natural rough stones. Although "jade is not cut, it is not a tool", the exquisite beauty polished by nature after hundreds of millions of years can never be compared with human artistic processing.

The ancients Li Bai said: "Clear water gives birth to hibiscus, and it is naturally carved." The appreciation of the original jadeite stone is natural, which is the highest realm of jadeite appreciation. Rare stones have also appeared in the natural rough stones in Huang Longyu. The value of Huang Longyu as the original stone lies in: first, it has extremely high ornamental and playful value; Second, it can be handed down as a fine jade material.
