Jade has the reputation of “King of Jadeâ€. Its natural charm, bright color, charming luster, crystal and warm texture have long been precipitated into a profound jade culture.
Jade evaluation can be viewed from its four aspects of color, texture structure, impurities and processing technology.
Color: Color is an important part of determining the value of jadeite. The color should be rich and uniform, and the color should be positive. In addition to green, the color of jade is also purple, yellow, red, gray, white, black and so on.
Texture structure: commonly known as "species", "water", the finer the texture, the better the transparency, the higher its value.
Impurity: Whether the texture is clean. Black spots, spots, cracks, and flower marks should be avoided when purchasing.
Processing technology: refers to the shape, size, thickness of the jade, whether the engraving is ingenious and the carving is fine.
Jade is divided into three levels: A, B, and C.
Jade “A goodsâ€, also known as “natural jadeâ€, means that jade does not change its internal structure, color and hardness after being processed by traditional techniques, but only changes its shape and appearance. The color is natural, the texture is moist, the structure is dense, delicate, and the hardness is high.
Jade "B goods", also known as "bleaching, filling jade", refers to the chemical, high temperature treatment, remove the impurities inside, and then inject transparent colloid, making it more crystal clear. The natural structure of “B goods†has been destroyed, the structure is loose, the durability is poor, and the value is reduced.
Jade "C goods" is also known as "dyed jade". More common in the market is the "B+C" jadeite.
As the saying goes, "Yu Yangren, people raise jade", the more beautiful the jade is worn, the more often it is the best maintenance for jade.
Similar varieties of jadeite are dyed quartzite (commonly known as "Malaysian jade"), green agate, dongling stone, and "material" (ie, artificial glass).
