The old pit is full of green jade. It is called the old pit. There is a reason for it. The Chinese people’s concept, the older the jade, including the jade, is the most beautiful, including darker colors and better transparency. Most of the jadeites are found in the secondary deposits in Myanmar, while the Burma jade secondary deposits are mined earlier. Therefore, it is called the old pit. The old pit and the new pit are actually divided according to the years of discovery and extraction of jade. According to the geological point of view, the geological ages they formed in the underground are the same. The secondary deposits of river sediments are formed by the rivers transported to the riverbed during the Quaternary period. It can be said that the deposits formed later are later. Some experts have discovered from long-term practice that the quality of the jade in the "Old Pit" is better and the water is also sufficient. This is a fact.
