Agate and chalcedony were first imported from Madagascar, mainly used for decoration, and most of them were processed into beads. Who would have thought that the original cheap stone would be so enthusiastically sought after in China, the price of stone soared by 100 times, and the identity of stone also took a gorgeous turn. Agate imported from Madagascar and chalcedony imported from the sea found their place in the stone appreciation world and quickly became popular.
Many people think chalcedony is a kind of jade, but chalcedony is actually a mineral, also called "chalcedony", and chalcedony is a timely variety. Chalcedony is a kind of ivory, shell-shaped, kidney-shaped and grape-shaped gem formed at low temperature and high pressure. It mainly occurs in pores, hydrothermal veins, hot spring sediments, clastic sediments and weathering crust. Chalcedony is waxy and often used in jewelry and works of art. In ancient times, agate was very popular. Agate has various colors of ripples, concentric lines, layered lines and other textures, delicate and free of impurities, full of luster, mostly translucent or opaque.
