Indonesian Moss Agate Palmstones

Intuitively chosen for you. Stunning moss agate from Indonesia. Each palm is approx. 3 inches by 2 inches.

Moss agate isn’t a true agate by gemological standards, since it lacks the traditional banding—but it is a form of chalcedony known for its moss-like inclusions of minerals like manganese or iron oxide. These inclusions form naturally over time, creating green to brown dendritic patterns that look like miniature landscapes or ferns suspended in quartz.

Despite the name, there’s no organic material in moss agate. Its striking appearance is purely mineral, formed in volcanic rock cavities as silica-rich solutions cooled and crystallized.
