First, the "species" of jade 1, glass floor: completely transparent and glassy; Fine structure and strong toughness; Even like glass, there is no cotton wool and stone flowers; It can be colored or colorless. 2, clear water: transparent as water, glass luster; There may be a small amount of cracks or other impurities; 3, egg white land: the texture is like egg white, and the transparency is slightly poor; Glass luster; 4, purple water land: the texture is translucent, but the purple is translucent violet; 5, muddy water: translucent texture, like muddy water; 6, porridge land: translucent texture, like porridge, also known as porridge land; 7.

Second, the "color" of jade (1), let's start with green: 1, and the glass is bright green: commonly known as "high green" and "crown green". The green is rich and bright, and the foundation is as pure as glass. Observed in sunlight or white light, the color tone is uniform and the transparency is good, which is the top grade! Generally, it can only be seen from jewelry magazines, auction albums and pictures that have been stolen on the website. 2, glass green: green is not rich enough, the tone is light, and it has good transparency when observed in sunlight or white light, which is the top grade; I still have a few such photos here, and I will post them for everyone to see in the future. 3. Bright green: green is rich but not pure enough. Observed under white light (2-5mm torus), the color tone is uniform and the transparency is slightly poor, which is superior; 4. Emerald green: green is like emerald, also known as "emerald", and its transparency is not as good as emerald; 5, Yang Qiaolu: emerald green, no yellow tone, emerald color is not strong; 6, boxwood green: yellow-green, the color is like the tender leaves of boxwood in early spring; 7.

Although there is green, the color is wrong; 2 1, grayish blue: there is impure blue in the gray, and the gray tone is dominant, and the impure grayish blue; 22, oil green: the color green is deep and impure, as unclear as oil immersion; Oil green: the color is dark and impure, darker than oil green, and the color is evil; Other varieties worthy of collection: Hong Fei: reddish brown, including red, light red, reddish brown and brown series tones, sometimes rust-colored, pure red is very rare; Violet; Commonly known as "spring colors" are purple, light purple and blue purple, and varieties with good water head and delicate texture are also rare. Yellow jadeite: yellow, brownish yellow, yellowish brown and beige are very rare; Fu Lushou: Red, green and purple are rare. Third, the "head" head of jade! What is "water head"? In fact, it is an evaluation standard of jadeite transparency in glass mill. Emerald can pass every 3mm under the transmitted light, which is called "one water separation" in the jade industry. The better the water head, the better the permeability. Accordingly, the less impurities in jadeite, the finer the texture. The smaller the mineral crystal particles are. Another factor that affects the head of jadeite finished product is the fineness of jadeite. The finer the texture, the better the visual effect of jadeite after polishing. Through these three articles, we can roughly identify the quality of a piece of jade (Burmese jade).
