Only by understanding the texture of jadeite can you distinguish the quality of jadeite

People who don’t understand jade may just marvel at its luster and appreciate the visual impact it brings. If you want to understand jade, you should carefully understand the texture of jade.

The texture of jade is the arrangement and order of crystal particles inside jade. Due to the long-term geological effects, jadeite raw stones are in a state of high pressure for a long time. The columnar crystal structure inside the jadeite will grow along the areas with less pressure, forming lines in the jadeite raw stones. The textures that exist inside the jade but are difficult to judge from the outside are mostly formed in the early stages of jade. The geological movement is caused by internal stress. In subsequent geological processes, they are often filled and healed by later minerals, so they are generally closed. Jade textures can be divided into: fly wing texture, orange peel texture, B+C acid etching texture based on their shape, and can be divided into: longitudinal texture and reverse texture based on their arrangement order.

On the mineral crystal surface and crystal cleavage surface that form jade, under light, the crystal surface and cleavage surface appear as needle-shaped, columnar or flaky shiny surfaces, much like the wings of an insect fly, referred to as "fly wings". The crystals of glass-type and ice-type jade are very small, and the "jade quality" is almost invisible, and it is difficult to see with the naked eye. Orange peel texture is jade-like wrinkles caused by the different hardness of jade's columnar and fibrous crystals. The high-hardness crystals are raised, while the low-hardness crystals are sunken. This unique phenomenon is called the orange peel effect. The acid etching marks are caused by the corrosion of strong acid in Jade B cargo. The gaps between jade mineral particles are very obvious. There is no smooth transition between the protrusions and depressions, but a crack separating them, forming cracks that penetrate between the jade mineral particles. These are called "acid etching marks". It can be said that jadeite with acid etching marks should never be purchased.

The raw stones on the jade market are also called seed materials, that is, jade gravel. The outer layer of the gravel is tightly wrapped by a weathered crust, which varies in thickness and has poor uniformity. From a mineralogical point of view, the appearance and texture of this skin vary greatly, and the grain is complex, sometimes very different from the internal mineral composition, and the color is difficult to grasp with the naked eye alone. Real jade appears transparent on the outside, but your internal texture can be seen under the light, and the stone structure is natural, delicate and smooth. Jade itself is a unique mineral that was formed and metamorphosed under conditions of low temperature and extremely high pressure after thousands of years of crustal movement. Like all minerals, chemical synthesis of jade is impossible, and there are absolutely no two identical jades in the world. Even if they look exactly the same on the outside, their internal texture structures are different, so each piece of jade is unique. Therefore, the unified standard pricing for different jades is also different.
