Chalcedony is one of the oldest jade varieties in human history. China appeared as an ornament in the Neolithic Age and has continued ever since. Chalcedony is generally used as the raw material of high-grade handicrafts for carving creation because of its rich colors and thorough texture. Personal ornaments such as bracelets, necklaces and pendants are also common.

The best chalcedony, especially the rare variety with bright colors, is mainly used for setting high-grade jewelry and customizing fashionable high-grade buttons, which is highly sought after by fashionistas and becomes a vassal of the upper class.

Because pure natural chalcedony has heat dissipation and is easy to lose water. Generally, it is not easy to lose water when you wear it often, and you don't need to soak in water often, which will get colder and colder. But in autumn and winter, the weather in the north is dry and it is rarely worn. It is best to soak in water regularly for 1-2 days, and the original luster and moisture will be restored soon.

But one thing should be paid special attention to: take it off before taking a hot bath or soaking in a hot spring; Because chalcedony is super afraid of heat and not resistant to high temperature, if you take a hot bath for several days, or often work in an environment with high temperature and close to fire, the chalcedony pendant will dry out due to water loss and become less transparent.

Extended data:

Ice chalcedony, also known as ice chalcedony, is rare in time.

Chalcedony is colorless to white when it contains no other minerals. When it invades the crystal matrix or other minerals in its crystal plane, it will reflect the color of its minerals, thus showing a gorgeous color. Therefore, it is named ice chalcedony, and the main representative variety is Jinjinshui Bodhi.

Because of its rich colors and crystal clear ice, it is also called chalcedony.

Ice chalcedony is common from colorless to white, and other colors are also produced. However, because red, green, blue and purple gems are common, golden yellow is the most precious chalcedony.
