About moss agate
Moss agate is a variety of chalcedony containing mineral inclusions—often of manganese or iron oxides—that resemble moss, ferns or other botanical patterns. The base chalcedony is typically colorless to milky white or lightly colored, with green, brown, red or black dendritic inclusions. With Mohs hardness around 6.5–7 and good toughness, it is suitable for cabochons, beads and carvings.
