Unlike other minerals, jadeite is divided into primary and secondary mines. The original ore jade original stone mainly refers to the jade original stone mineral that has not been transformed by the relatively weak post-dynamic geological function, and is called a new pit or a new field.
The secondary ore of the jade original stone refers to the jade original stone mineral after the natural geological action such as weathering, earthquake, river water and so on. It can also be water stone or water turning sandstone, usually called old pit or old field.
Old pits and new pits often cannot represent the old or new geological age of jadeite, but are differentiated by the geographical and geographical distribution of geology and minerals. In fact, those new pits and old pits are mainly used to describe the quality and quality of the jade stone. As long as it is a high-transparent, high-quality, clean and delicate jade stone, it will be called the old pit jade stone.
The original pits of the original pits of the new pit are generally common, with no outer skin, rough texture, relatively large internal crystal particles, poor water head and low transparency, so it is called a new pit.
The secondary jade stone of the old pit is relatively fine in texture, with a leather shell, small internal crystal particles, good water head and high transparency, so it is called the old pit.
In fact, high-quality jade original stone will also appear in the original mine, and the difference from the secondary mine jade stone is not very large, it can also be called the old pit species. The current production of the old pit jade stone is very small, and most of the old pits on the market now come from the new pit. There is also a half-mountain and half-water jade stone, texture and seed between the new pit species and the old pit species, called new and old species.
The “new pit†and “old pit†that are often said in the market are generally a measure of the quality and difference of the original jade stone. It is rarely pointed out that the jade stone is produced in the mining area. Therefore, as a consumer, you do not need to have these two terms. Too much mystery.
