What is the difference between chalcedony and jade? So what do you think is the difference between chalcedony and jade? Chalcedony is the jade of quality, and it is a big mistake. The chalcedony that people generally say is high-quality agate, a saying that business owners are trying to confuse customers. Chalcedony is always mistaken for people to be a kind of jade, the essence of jade. Chalcedony is made of condensed jade liquid. Its fine particles, its main mineral composition is cryptocrystalline quartz, the shape and size are different, the gloss is mostly glass or waxy, translucent or slightly transparent. But often some people can't tell the difference between chalcedony and jade, then let me bring you to reveal the mystery of the difference between chalcedony and jade!
Chalcedony
One of the differences between chalcedony and jade:
First of all, we must understand the definition of both chalcedony and jade. Chalcedony belongs to "jade" but does not belong to "jade". Hyundai divides "jade" into two categories: jadeite and nephrite. Jadeite is jadeite, and jadeite is jadeite produced in Myanmar. Nephrite mainly refers to Xinjiang and Yuyu (that is, Hetian jade). Nephrite is produced in many places in China, such as Hetian jade in Xinjiang, Xiuyan jade from Liaoning, Dushan jade from Nanyang, Henan, and Lantian jade from Shaanxi. The concept of "Jade" is much larger than "Jade". Hetian jade, jade, crystal, amber, agate, coral, etc. are all jade. Chalcedony, also known as Australian jade, is a cryptocrystalline quartz crystallite aggregate. The color is yellow-green-green and jade is similar. The green chalcedony is a weathered leaching deposit. The shape of the original stone is irregular block, chalcedony. It is also one of the jade. Chalcedony is also often used as a gemstone, mainly used as a material for arts and crafts.

The difference between chalcedony and 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.
In jade, the jade that is easy to be confused with chalcedony is Dongling Stone, Miyu, Jasper and so on. So pay special attention when shopping. They can be distinguished from the color of the texture and so on. The texture of chalcedony has a cryptocrystalline structure, and the particles are tiny and cannot be seen by the naked eye. The most obvious thing about Dongling Stone is that the particles are large and the texture is coarse and rough relative to the chalcedony.
The difference between chalcedony and jade is that the composition is completely different. In fact, the main mineral component of chalcedony is cryptocrystalline quartz, which has different shapes and sizes. The gloss is mostly glass or waxy, translucent or slightly transparent, and is the same as agate. Kind of mineral. Personally think that chalcedony is a high quality agate, chalcedony is just a saying that business owners are trying to confuse customers. At present, there is a saying that the ice seed chalcedony that appears on the market is borrowed from the "ice type" jade, which is a gimmick of commercial speculation. The chalcedony products are bright, cryptocrystalline structure, the texture is extremely fine and uniform, the naked eye does not see particles, because the individual unscrupulous commercial green chalcedony impersonates green jade, so you need to pay attention when purchasing.

However, because there are many kinds of jade, it is impossible to compare the common and the chalcedony, so I have selected several jade similar to the chalcedony for comparison. Better to let you know the difference between chalcedony and jade.
Green jade, turquoise, etc., are also easily confused with chalcedony, and they can be identified by careful observation. Green jade has a fibrous shape, no chalcedony; turquoise, low transparency, low hardness, and porcelain luster.
Green chalcedony and green jade
The surface of the green chalcedony is bright and delicate. The color is usually apple green, which can be seen in varying degrees of depth and translucency. The green chalcedony is brittle and will fade when heated or exposed to sunlight. The green jade has a variegated interwoven structure, and it can be seen as a patchy or fibrous jadeite crystal. The appearance is glassy, ​​mostly translucent or transparent, and the emerald color is pure and pure. In terms of weight, the green chalcedony with a specific gravity of 2.60 is much lighter than the jade with a specific gravity of 3.24 to 3.43.
Green chalcedony and turquoise
The green chalcedony is generally translucent with a Mohs hardness of 6.5 to 7; turquoise is usually opaque and has a low Mohs hardness of 5 to 6. Both are very easy to distinguish.
