What is Agate
Agate is a kind of cryptocrystalline quartz, and its main chemical composition is silicon dioxide. The hardness of Agate on the Mohs scale is between 6.5 and 7.5, and it looks translucent or opaque. When underground magma erupt, the natural holes on the rocks are filled with silicon dioxide. The mineral crystallized from silicon dioxide is called Agate. Many people are not able to distinguish Agate from Chalcedony since their composition is the same. However, the most difference lies in the stone structure. Agate is with banded form, but Chalcedony isn't.
