The important basic knowledge

Jade is trade name in market, the Dana classification sodium aluminosilicate, they are growing in granite stone groups.

During the Ming Dynasty, people always regarded “quality” is most important of jade, the higher quality jade is judged by positive green (as known emerald green or imperial green ) . The colour of jade is bright and varied, including green, lavender, white , pink, brown, red, blue, black, orange and yellow. Among them, the precious emperor jade, which is rich in positive green colour, it is known as the “ old pit type jade”.

The important basic knowledge

1.In fact, the "old pit" is the first excavated jade pit previously recorded, and it is not used to distinguish the grade of jade.

The so-called "Old Pit" is the first pit at the time when jadeite was first found, called "Old Pit" in order to mark the first pit where the jade was discovered, and later the mark of the pit became a digital sign. Because pit factories are located in different regions of Myanmar, and the varieties and textures of jadeite produced in different regions are also different, at the same time, Myanmar also produces rubies, sapphires, and red garnets. Among other natural ores, not only jadeite.

2. The most significant difference between the old pit species (commonly known as jadeite ) and the new pit species (commonly known as nephrite) lies in the "hardness".

The old pit species (as known jadeite) hardness is 7, and the new pit species (as known nephrite ) hardness is 5-6.

Some people may misunderstand: old pit = old species, new pit = new species, in fact, but "old and new" is suitable for us to distinguish "jadeite and nephrite", Myanmar is adjacent to China, and there are many natural mining areas in many regions of China. , such as Hetian jade, 羊脂白玉 white jade, 新疆 white jade, these are natural and precious high-grade nephrite jade, which is also what we call new jade.

Of course, there are more countries with nephrite. Including Australia, Russia, Taiwan and other regions.

In fact, there are jadeites produced in "Guatemala". This kind of jadeite is relatively thin, but at first glance, it is very similar to the jadeite of Myanmar, and there are many kinds of colour. Therefore, when buying jadeite, you need to pay more attention.

*According to the different factions studied, there will be slight differences in the "species, water head and colour of jadeite, as well as the name of species, colour and carving meaning of jadeite."

*This article does not distinguish between good and bad, because any valuable gemstone and jade will fluctuate in price due to market demand.*
