Description

This kind of chalcedony is also known as "Fossil Bamboo". There are different opinions about the genesis: some think it is chalcedony which represents overgrowths of iron oxide rhizolite. Others say it is agate casts after a variety of marsh grasses or other wetland plant stems. However, the chalcedony (or agate) is unusual and impressive. Finger-shaped agate with great construction and color. The agate fingers are transparent in the outer area. Impressive play of colors! This piece comes out of its pocked in perfect condition.
