Among the unearthed jade articles, agate ball strings are more common, mostly necklaces.

Generally translucent to opaque, the hardness is 6.5 to 7 degrees, the specific gravity is 2.55 to 2.9 1, and the refractive index is 1.535 to 1.539. Agate has a very long history and is one of the earliest gem materials used by human beings. Agate can be formed in all strata of geological history, whether igneous or sedimentary. So there are many agates. China agate is widely distributed in almost all provinces, mainly in Heilongjiang, Liaoning, Hubei and other regions.

Agate is mainly produced in cracks and caves of volcanic rocks and also in sedimentary rocks. It is a colloidal condensate of silicon dioxide. Like crystal and jasper, agate is also a timely mineral, and its chemical composition is also silica. Its hardness exceeds that of crystal.
