Diancui is a jewelry making process in ancient China. It became popular in Han Dynasty and reached its peak in Kanggan period in Qing Dynasty. The jade in it is the feather of kingfisher. To make this kind of jewelry, gold and silver are used as the base, then gold wire is used as the groove on the edge of the base, and finally kingfisher feathers are stuck on the base to make jewelry of various shapes, and sometimes pearls, jadeite and other gems are embedded in the pattern. Although no other jewelry can make this jewelry stand out, it is noble and elegant. Generally speaking, the Queen's rockhopper adopts the "Diancui" craft.

The kingfisher's feathers are very bright. Some people think that the decorations made of kingfisher feathers will never fade. Actually, it's not. The color on the jewelry can only be said that it is not easy to fade. These ornaments will be preserved for about 100 years, and their colors will gradually fade.

In some treasure variety shows, there are many ornaments made by folk heirlooms for experts to identify, but most of them are due to improper preservation. Some of the kingfisher's feathers were eaten by insects and ants, and some lost their original luster and became dull.

It is said that when collecting kingfisher feathers, live kingfisher feathers are usually cut off with scissors and then stuck on ornaments. However, because it is too cruel to the kingfisher, the kingfisher with feathers will soon die.

So in the early years of the Republic of China, the process of making jade was replaced by the process of burning blue. Later, the kingfisher was listed as a national protected animal, and all the decorations were replaced by other substitutes. This process has gradually disappeared now.
