Moss agate is a type of chalcedony, a form of quartz known for its unique appearance characterized by green or blue-green inclusions that resemble moss or foliage, giving it its name. These inclusions are typically formed by minerals such as chlorite, hornblende, or other manganese or iron oxides. Moss agate often has a translucent to opaque appearance with a waxy luster.
The color variations within moss agate can range from light to dark green, sometimes with hints of brown or black. Its appearance can vary widely, with some specimens featuring fine, wispy inclusions resembling delicate ferns, while others may have more prominent, branching patterns resembling trees or landscapes.
