1, old pit species
Emerald with positive, strong, sunny and uniform color can be called "old pit species", which is mainly used to describe the color of jadeite. This kind of thick green is evenly distributed, high in concentration and bright, generally delicate in texture and not necessarily transparent. If the transparency is high and the moisture is sufficient, the effect will make the color and texture of jadeite look better. Experts call it Qi Ying, which is bright and dazzling, and has the name of "old pit species".
2. Gan Qing species
It belongs to middle and high-grade jade species and is divided into two categories: one is pure sodium chromate. Aluminum is replaced by chromium, and the chromium content is above 50%. The other is that aluminum has not been completely replaced by chromium. Besides sodalite, it also contains jadeite and tremolite. This jadeite is rich and pure in green, with poor transparency and difficult light transmission.
3. Green species on white background
It is one of the most widely distributed jadeites in Myanmar. It is characterized by fine texture, often fiber structure, generally white background, of course, sometimes there are some impurities. The green color of "green species with white background" is more vivid, because the white background is more bluish white, and the green part is mostly round, which is different from "flower green species".
4. Green species of flowers
It refers to a kind of jadeite whose green distribution is veined and very irregular. Its background color may be light green or other colors, and its texture may be coarse or fine. For example, the "flower blue at the bottom of the bean" has a coarse structural grain and is called the bottom of the bean. Its color is irregular, sometimes densely distributed, or sparse, deep or light, so this kind of jadeite is called flower blue.
5. Oil green species
The color is not pure green, with gray or some blue, so it is not bright enough. It can also be said that the color is dim. Its color can go from shallow to deep, and its transparency is generally good. It is usually fibrous and can be thin. Because its surface luster resembles oily luster, it is called "oily green species". If its color is dark, experts also call it "melon skin is oily green".
