Chalcedony is distinguished from agate: there is no strip-like texture

When buying jade jewelry, I often encounter something called "chalcedony". What is it, and what is the difference with jade? Is it agate?

It is understood that there are many types of jade, in addition to the traditional Hetian jade, jade, but also agate, crystal, amber, chalcedony and other gemstones. For chalcedony, many people mistakenly believe that it is the essence of jade. In fact, chalcedony is not a jade, but a kind of jade. Many people will also confuse chalcedony with agate.

Chalcedony is a common jade variety in nature. Its composition is mainly SiO. In addition, chalcedony is rich in trace chemical components and mineral components, such as e, AL, Ti, Mn, Mg, K, etc., so the color of chalcedony is very rich. The pure chalcedony color is colorless or white, translucent to slightly transparent. The common chalcedony products on the market include chalcedony pendants, rings, bracelets, earrings, etc. Usually the price of chalcedony varies from tens of yuan to thousands of yuan. The sound of knocking on the chalcedony sounds boring.

The main component of agate is silica. Due to the inclusion of oxidized metal, the color can range from very light to dark. The high-quality natural agate texture is natural and smooth, emitting glass and oily luster. Compared with chalcedony, the color of agate has a strong layering, clear color and obvious bands. In addition to distinguishing chalcedony and agate by tapping the difference between chalcedony and agate sound, chalcedony and agate can be identified from the presence or absence of a strip-like texture. The banded texture is chalcedony, and the obvious strip-like texture is agate.
