Generally speaking, there are crystal particles on the jade bracelet, commonly known as flying wings, which refer to the jade surface. Under the illumination, the cleavage surface of jadeite minerals presents a bright white reflection surface, similar to the wings of flies. If it rotates under the light, the wings of flies in different parts will appear flaky flashes of different sizes, one after another.
3. The granularity of jadeite proves that jadeite is tender and belongs to inferior jadeite, which leads to obvious crystal structure of jadeite. But the obvious crystal structure is usually mostly bean jadeite. Because of its rough texture, the appearance of jade pieces is inevitably rough, and the luster and transparency are often poor, which is often called "water drying" in the jade industry.
4. The "ice crystal" in your bracelet is the flying wing phenomenon caused by tender seeds and loose structure. If you can see it, it means that the variety is tender and the structure is loose.
