Judging the value of jade devices

The value of the jade device is judged by the following aspects:

(1) Color, so-called positive, yang, thick, and uniform. (Positive: refers to the degree of purity of the color; Yang: refers to the brightness of the color; Concentration: refers to the saturation / shade of the color; uniform: refers to the uniformity of the color distribution.)

(2) Texture: Also known as the thickness.

(3) Transparency: commonly known as "water head"

(4) Engraving: the level of engraving technology

(5) Weight: the mass of jade.

The price of jade products is generally not affected by the age, which is different from nephrite. However, the new jadeite is worth more than the jadeite carved in the Qing Dynasty. The color of the color jade is white or green due to the difference in the mass fraction of chromium contained. Generally, white and green types are the most common, and emerald green is expensive.

colour

It is white or green due to the difference in the mass fraction of chromium contained. Generally, white and green types are the most common, and emerald green is expensive.

The colors of jade are mainly:

(1) White: substantially free of impurities.

(2) Red: Contains ferric iron.

(3) Black: Contains more than 2% chromium.

(4) Green: Contains more than 2% chromium and ferrous iron.

(5) Yellow: Contains elemental bismuth.

(6) Purple: Contains elements of chromium, iron and cobalt.

The green jade can be further divided into gemstone green, emerald green, green seedling green, green green, green bean green, spinach green, and shallow green. The color of jade is positive (pure), yang (sharp), rich (rich), and even (even). Gem green, emerald, green seedlings, green four can be called top grade, and four of them are the most precious. This type of jadeite is single, generally transparent or translucent, without the appearance of color roots. Like our common ice and glass jade, it is a colorless series. This kind of jade is pure and flawless, crystal clear, and is the representative of perfection and purity. As early as 2001, this kind of jadeite was not optimistic, but it has now been listed as a good choice for collection.

texture

The texture of jadeite refers to the roughness and delicateness of the jade structure. Mainly reflected in the size of the crystal particles.

Ground

It refers to a place other than green in jade, which is called Hong Kong. The species of jade are mainly glass, ice, glutinous rice, bean, porcelain, and other oil-green species. Among them, the glass is the best in jade.

transparency

The transparency of jade, also known as the head, can be divided into transparent, transparent, translucent, micro-transparent, and opaque to varying degrees. The higher the transparency of jade, the higher the value.

pit

The earliest mined pits have fine and high-quality jade textures, and the later mining is getting bigger and bigger. Most of the newly opened pits cannot catch up with the former pits. Therefore, in the later period, people used to think that the jade of good quality is old. The slowly old pit becomes synonymous with high quality.
