Also known as "moss opal" and "merlinite", dendritic opal is classified as a common opal. It features fern, moss, or tree-like patterned inclusions (referred to as dendrites) of metallic oxides like manganese and iron, which give it its name. It generally is milk white in color with black or grey patterns, but it can also appear yellow, blue, or brown in color.
