Because of its dense and delicate texture, gorgeous color, high hardness, good luster, good polishing performance and certain transparency, it is very popular among jade lovers, and its origin is scarce, so it is rare in the market, belonging to high and medium-grade jade materials, also known as jade.

The ancients said that jade can't be cut and gold can't be cut. Jinyu has been buried underground for 700 million years. Jade contains a lot of mineral elements. If people wear jade for a long time, the water head of jade, that is, the refraction, will become better and brighter. If people are in poor health and wear jade for a long time, the mineral elements in jade will be slowly absorbed by the human body to achieve health care!

The common jade products in the market are mostly white, beige and red. The ancients said that wearing jade is beautiful. As the saying goes, gold is valuable, but jade is priceless. Jade is not only the symbol of happiness and wealth, but also the embodiment of nobility and taste.

Wearing jade is not only a symbol of aristocratic status, but also a dream of ordinary people. Everyone has it, which can better express the extension and inheritance of China jade culture.
