How to identify gemstones (jade) similar to jaundice

In recent years, with the rising temperature of the jade market, the green jade has attracted much attention. In addition, Huang Wei has also been loved by Cuiyou. Yellow symbolizes rights, wealth and light. Huang Qi is often engraved into carvings such as dragon cards, Guan Gong, Jin Yu and Yi, which are favored by Cuiyou. However, there are some jade species similar to Astragalus in the market, and the Cuiyou who do not understand the jade are deeply affected. Knowing their respective characteristics helps to distinguish between true and false.

I. Identification characteristics of Astragalus

1, green

Due to the special internal characteristics of the jadeite, the internal structure is destroyed during external force or processing. Under the illumination, the gleaming facets can be seen, commonly known as "fly wings flash".

2, orange peel effect.

The surface of the jadeite is often undulating like orange peel. This phenomenon is determined by the nature and structure of the emerald crystal.

3, the luster of jade.

Gloss is a phenomenon caused by surface reflection. Polished, densely textured jadeite, due to its smooth surface, can be glassy.

Second, yellow nephrite

Nephrite is a traditional jade in China, in which white is regarded as a treasure. Common colors are white, white gray, green, yellow, black and so on. Yellow nephrite has a large output and low price. It is suitable for imitation jade.

1, surface features

The polished nephrite, due to its very fine mineral crystals, often exhibits a lustrous surface and does not have the unique green and orange peel effects of jade.

2, color distribution

The color distribution of nephrite is evener than that of jade, and unevenness is rare.

Third, agate

Natural agate stone is hard, lubricated and dignified. Natural colors are mainly red, amber (yellow) and white. Among them, red is the best. Domestically produced in Liaoning, a new agate, not only rich in color, magnificent texture, full range, but also produces precious water agate.

The thing that agate does has a fatal flaw---the relative density is smaller than that of jade, lighter than jade, and accompanied by obvious ribbon.

Fourth, Huang Longyu

Originally known as yellow wax stone, because it is produced in Yunnan Longling, and is mainly yellow, it was finally named Huanglongyu. Its main color is yellow and red, and the bright yellow Huanglong jade is comparable to the top Tianhuang.

Because the crystal structure of Huanglongyu is different from that of jade, there is no such thing as the "fly flies flash" and orange peel effect on the surface. Secondly, Huanglongyu is a grease luster, and the luster of the grease is not bright.

Five, calcium aluminum garnet jade

The main producers of domestic calcium aluminum garnet are Xinjiang Altai, Qinghai, Guizhou, etc., with abundant production. Calcium aluminum garnet has a color ranging from colorless to black, depending on its elemental content and color.

1. In the calcium-aluminum garnet jade, there are coarse green calcined garnets with coarse particles.

2, if Cuiyou has a small instrument for professional identification in hand - Charles filter, calcium aluminum garnet jade

Six, yellow jade

Saitama is a kind of serpentine jade. The color of serpentine varies, the variety is varied, and the name is not uniform. The name of the place of origin is often used as the name. The name of the rock in Liaoning is called jade. Due to its large production area and large output, serpentine jade has a similar color to jadeite and is often used to counterfeit jade.

The relative density of jade jade is much smaller than that of jade, and the handcuffs will feel lighter and easier to distinguish. Secondly, Saitama has a characteristic white cloud-like mass.

The above identification points are for reference only. If you don't know much about jade expertise, you can send it to the quality inspection agency for inspection before purchase.
