Moss agate is a variety of chalcedony with contrasting white and green moss-like patterns. Its green coloration comes from a mineral called chlorite, while the reds and browns come from manganese oxide or the oxidation of iron hornblende. Moss agate is generally cut into thin slabs and polished to best display its natural patterns. Often moss agate cabochons are used in distinctive jewelry designs.

This agate variety is termed "dendritic" due to its internal collection of dendrites. Dendrites are fern-like inclusions of iron, manganese, or other metallic oxides that create bold patterns within the gem. Typically, dendritic agates are cut into slabs to best exhibit nature's artwork. As you might guess, these pieces are one-of-a-kinds, as no two dendritic patterns are exactly the same.
