From ancient ancestors to modern times, people have always had a soft spot for jade. Ai Yu, Jing Yu and Chong Yu have a long history and have already integrated into Chinese culture. Jadeite was introduced to China from the late Ming Dynasty and the early Qing Dynasty. However, with its rich colors and high hardness, it has won people's love and quickly occupied the market. But what followed was that various counterfeits were emerging. Summarize the jade counterfeit products that often appear in the market. I hope that everyone can polish their eyes when buying jadeite and avoid being deceived.
1. Sodium feldspar jade (also known as "water foam")
Sodium feldspar jade is also known as "water foam, its main mineral component is albite, and jadeite is a mineral aggregate of pyroxene.

Because chalcedony is cryptocrystalline, the internal structure is not visible. The internal structure of jadeite is a typical fiber, which is often countered as a high-grade jade jewelry with high-grade water.

It has a lower density than jadeite, its relative density is 2.6, and the relative density of jadeite is 3.34.

7, grape stone
It is a silicate mineral, usually they appear in the hollows of volcanic rocks, and sometimes they can be seen on stalactites. The color of the grape stone ranges from light green to gray, as well as white, yellow and red, but the common color is green.
Identification method: uniform color, no green. Simply put, the flies' wings (ie, the jadeite's "green"), the glass luster, and the internal fiber interweaving structure are important basis for the naked eye to initially identify jade.
Friends who like jade, when buying jade, these common sense must be paid attention to. But now the jade market is ever-changing, and the way of fraud is also endless. It is not enough to identify it by the naked eye. Be sure to issue a jade identification certificate from an authoritative organization before you can buy it with confidence!
