Chalcedony is often mistaken for people to be a kind of jade, and because of its name, it is the essence of jade. It is very rich in color, with dark green, apple green, blue, etc., among which green is the most beautiful. But many people still can't distinguish the difference between jade and chalcedony. So what is the difference between jade and chalcedony? First, we need to figure out the definition of both. In mineralogy, the definition of strict jade only includes a few jade varieties, such as jade, Hetian jade, etc., which have no chalcedony. However, the concept of "Jade" is much larger, and the chalcedony is one of the jade. Secondly, the composition of chalcedony and jade is different, which is an important reason for the difference between the two. The main component of jade is Ca2(Mg,Fe)5Si8O22(OH)2); the main component of chalcedony is silica (SiO2), which is a collection of cryptocrystalline quartz. In this way, they are not the same type of substance.
