Moss Agate is a unique variety of agate, known for its internal green inclusions that form irregular patterns resembling moss and underwater plants, creating a miniature reflection of the natural environment. Rare varieties of Moss Agate may feature blue or purple agate, which adds to their desirability. When this mineral was first discovered, people believed that the inclusions were actual organic matter or plant remnants. However, modern technology has confirmed that the patterns are made of inclusions from oxides and other minerals. Despite not containing plant materials, Moss Agate has long been used to help connect with nature and can be found in various rituals and customs throughout history.

In ancient cultures, Moss Agate and crystals containing manganese oxide (which has inclusions resembling branches) symbolized plant growth and were associated with crops and natural forces. As a result, it was frequently used in rituals to ensure a bountiful harvest and protect crops. Over time, Moss Agate also came to represent abundance and prosperity.
