When looking at jadeite, we have to mention the stone patterns and cracks

There is an essential difference between cracks and lines. Literally speaking, stone lines refer to the texture of the stone, which are produced during the formation process of the stone itself and do not affect the texture of the stone itself. Stone cracks are caused by external forces after the stone is formed, which affects the overall texture and integrity of the stone.

Jade is a gemstone made up of a variety of minerals. The formation process is complicated and there will be more or less impurities mixed in it. In trade, we should adopt a rational attitude towards these impurities. Some impurities that do not affect purchase and daily wear can be appropriately considered, such as some cotton wool or stone patterns; while those that seriously affect buying and selling and wearing should be avoided, such as cracks.

Cracks are also called streaks in the industry. Smaller cracks inside jade are called streaks. Streaks are small cracks that are congenital in the formation process of jade, and are mostly found inside jade. Cracks are cracks caused by jade during later carving, processing, sales, transportation, playing and collection. They are usually on the outside of jade and can be felt by sliding your fingernails. In the jade market, you can often see merchants using flashlights to look at jade, some of whom are observing internal cracks. Because cracks will prevent light from entering.

Stone veins are mineral veins formed by later filling and crystallization of cracks formed earlier. They are a common type of healed cracks. Unlike cracks, stone patterns will neither block the entry of light nor feel cutting, and the existence of stone patterns will not destroy the internal structure of jade. However, you should pay attention to where the stone patterns appear. For example, in sculptures of Buddhas and Guanyins, the stone patterns should not appear on the face, as this will not only affect the appearance but also greatly reduce the price.
