How to identify the authenticity and quality of Huanglongyu?

This is generally the statement of the appraisal certificate, depending on the specific things, because the Huanglongyu market is relatively chaotic, especially in the tourism market, many substitutes will pretend that the Huanglongyu diamond is not of origin significance, such as Xinjiang Sancai stone and Yantai yellow-white mineral jade and Taishan crow skin. However, I think that Huanglongyu is still of higher quality in Longling's origin, after all, this is a new jade, and there is a limited resource like Hetian jade that needs to be replaced by other mineral veins. Merchants use substitutes because they are cheap, for example, the cost of Sancai is only a few tens of dollars, and you can buy dozens of hundreds of times.

Specifically, you send **, I'll see what material. If it is purchased in a tourist market or a tourist city, it is basically suspended.

The "Huanglongyu" you bought may not be Huanglongyu, hurry up and find out!

Huanglongyu is a new jade species discovered in Longling, Yunnan Province in 2004, which has the color of Tianhuang and the hardness of jadeite. High hardness, good transparency, warm and delicate texture, bright and rich color, loved by people.

Huanglongyu has important elements such as beauty, rarity, and durability, and has rich color, dense structure, high hardness, excellent oiliness and toughness, all of which are in line with people's aesthetics of jade. Because it is produced in Longling, and yellow is the main color, it was later named by the Yunnan Ornamental Stone Association"Huanglongyu" 。

Before it was used as jade, it was called "yellow wax stone". Guangxi stone merchants found this yellow stone in the Supa River in Longling, Yunnan, its stone is fine, the color is golden, the block type is huge, the color is rich, it has a high ornamental value, and it is sold to Guangxi as an ornamental stone after mining. Therefore, in the last century, it was collected and bought and sold as an ornamental stone.

Huanglongyu is an aggregate of cryptocrystalline minerals with silica as the main component, with delicate texture and high hardness. Because it contains different impurity mineral components, it shows a variety of different colors. The colors are extremely rich, including yellow, red, white, gray, black, brown and very rare purple, green.

There are different shades in a variety of different colors, such as chanterelle yellow, orange yellow, bright yellow, earth yellow, etc.

Huanglongyu is divided according to its composition, and the main component is silica, which belongs to quartz jade. When the appraisal certificate is issued at the quality inspection station, since Huanglongyu is a local name, quartz jade will also be displayed on the certificate. The production of Huanglongyu is relatively limited, and many merchants will also use ordinary quartz jade to act as Huanglongyu for sale.

Quartzite is generally white, crystalline, translucent to opaque, and other properties are the same as Huanglongyu, and it may be easy to be fooled if you don't understand these varieties. Huanglongyu can be judged from the following aspects:

Structure, Huanglongyu is an anaphthic structure, the structure is very dense and delicate, and the granular feeling cannot be seen with the naked eye. Ordinary quartzite has a granular structure, and the graininess can be easily seen by illuminating the interior with light.

Color, Huanglongyu color is natural, contains different trace mineral components to cause color, rich in color, there are transitions between colors. Quartzite is basically white in color, and dyed quartzite can often be seen in the market to pass off as jadeite or other jade, which is very similar in appearance. But quartzite is a granular structure, and when dyed, the color is distributed along the edge of the grain, also known as a loofah pulp-like distribution.

Stained quartzite has very typical dyeing characteristics and can be easily distinguished.

<>1. Look at the color.

Huanglongyu is rich in trace elements, famous for its more color, and its color is mainly yellow and red, so when identifying Huanglongyu, color has become the key. The color distribution of real Huanglongyu is uneven, the texture is transparent, and the color root of Huanglongyu can be seen to the light. And the fake Huanglongyu, the color is vague and not very real.

2. Look at the texture.

Huanglongyu is an aggregate of cryptocrystalline minerals, the larger the volume, the better the quality, and its interior generally has flocculent structure and radish silk lines, as well as some black pitting. And the texture of Huanglongyu is delicate, and the tentacles are silky and warm. Therefore, when it comes to identification, Brother Mu is not waiting, and he must look at the texture and touch of Huanglongyu.

3. Look at the gloss.

The luster of Huanglongyu is divided into dust mold grease luster, waxy luster, and vitreous luster. The natural Huanglongyu has a strong texture, and when the light shines on the Huanglongyu, it gathers together and looks very bright. Fake yellow dragon jade is not as shiny as real yellow dragon jade, and the reflected light does not have the feeling of concentrating.
