After reading this, you will understand what Chalcedony is.

As a rising star in the collection market, chalcedony has the characteristics of being hard, delicate, soft, transparent, and rich in color, and is highly sought after by fashionable people.

The price of chalcedony is still at a low level, and with relatively few counterfeit goods on the market, its current investment risk is small.

The color of chalcedony is very rich, and the chalcedony of purple, blue and green colors can be described as fine products due to low yield, and the highest value is preserved, such as the chalcedony of Brazil and Indonesia. The color of chalcedony of yellow, white, red, black and other colors is relatively large, so the collection value is relatively low, and the price of each piece usually ranges from several hundred yuan to several thousand yuan.

In fact, chalcedony is a jade, not a jade. “The definition of “jade” in mineralogy is very strict, including only a few types.”

The scope of "jade" is much more common. For example, our common jade, amber, agate, and chalcedony are all in the jade category. According to the introduction, the composition of jade and chalcedony is quite different. The main component of jade is calcium silicate containing magnesium ion and ferrous ion; the main component of chalcedony is silica, which is the confluence of cryptocrystalline quartz. In this way, they are not the same type of substance.

Because chalcedony is very close in composition to jade, many people confuse the two. It is not difficult to distinguish them:

First, it is judged from the glossiness. Both jade and chalcedony have glass luster, but the emerald's luster is not as clear and transparent as chalcedony;

Second, it is discriminated from the internal structure. The interior of the jadeite is a staggered structure of fibers, and the chalcedony is a granular structure;

Third, it is determined by weight. The density of jade is greater than that of chalcedony. Therefore, the jade feels heavier than chalcedony;

Fourth, discriminate from the sound. When the two emeralds collide quietly, a loud sound will be emitted, and when the two chalcedony will collide with each other, a dull sound will be heard.
