agate

Agate is a type of chalcedony, which is a polycrystalline quartz, and mainly refers to chalcedony with striped patterns. The Japanese name is "Agate", which many people may be more familiar with. Because agate has the property of being easily colored, there are many pieces that have been colored to change the color or have a pattern that stands out clearly.
