How to distinguish between turning on the light and not turning on the light

Distinguish between lights on and off as follows:

1, gloss

The gloss of an object can be seen whether it has been polished or not. The polished object has bright and round surface luster and good hand feeling. The surface gloss of unopened objects will appear a little dim and feel ordinary.

2. Features

Whether an object is opened or not can be seen by the mark. After some objects are opened, the master of opening and blessing will leave a mark of "_", but not all objects are opened. This mark will never appear on an unpolished object.

3. Texture

Whether an object is polished or not depends on its texture. Usually, the texture of the polished objects will not be too bad, and they are basically superior materials. Things that have not been polished are mostly of poor quality and cheap.

Classification of jade

According to GIG's research, jade can be divided into nephrite and jadeite. Nephrite is a traditional jade material in China, and its name comes from nephrite. Because nephrite is produced in Hotan area of Xinjiang, people often call nephrite "Hotan jade". The hardness of nephrite is generally 5.6-6.5 degrees, and it is opaque or translucent. Nephrite can be divided into the following categories by color: white jade, topaz, sapphire, (blue white jade), jasper, black jade, flower jade and Tang jade. Jadeite refers to jadeite produced in Myanmar.

Whether nephrite or jadeite, their texture is very hard and their colors are very bright, so they are known as "the king in the stone". Jade is inherently valuable, and it has become priceless after being processed and carved by skilled craftsmen. With the development of the times, jade has gradually formed a jade culture.
