At first glance, many people think that old pit jadeite has a longer formation period, but this is a misconception. Generally, jadeite pebbles produced in Myanmar that have fallen into river valleys and riverbeds due to tectonic movements are called "old pit jadeite"; while jadeite raw materials extracted from the original place without weathered surfaces are called "new pit jadeite." From a geological perspective, they formed in the same geological period underground, not as long as people imagine. However, "old pit" jadeite is of better quality, and its "water head (transparency and luster)" is also sufficient, which is mainly related to the transportation of old pit jadeite by water. The primary jadeite ore deposits actually contain various types of ores with different qualities. After being transported by water flow and deposited as secondary ore deposits, the lower-quality jadeite, such as those with cracks, coarse grains, loose structures, or impurities, is naturally selected and eliminated. The jadeite that remains in the riverbed is mainly those with denser textures and finer structures. It is this natural re-screening process that results in the high quality of old pit jadeite. Uncarved old pit jadeite has a layer of weathered surface. This is because after the jadeite is exposed to the surface, it undergoes oxidation and hydrolysis in nature, causing the iron oxide or manganese oxide it contains to adhere to the surface, forming a protective layer, similar to how a rarely used knife rusts on its surface. Although "old pit" jadeite is of better quality, "new pit" mountains also have high-quality jadeite, but they are relatively rare. This is the result of unsorted selection. P8-9
