Geology & background

Forms when manganese or iron oxide minerals crystallize in branching patterns inside fine chalcedony or agate.

Dendritic Agate has long been cut for cabochons and ornamental stones because of its landscape-like patterns.

How to identify Dendritic Agate

• Look for the distinctive color, pattern, and translucency associated with Dendritic Agate.
• Photograph a fresh or polished surface in natural light and avoid glare.
• Use hardness, luster, fracture, and locality together; many chalcedony trade varieties overlap visually.

Where Dendritic Agate is found
