Dendritic opal is a milky white to golden yellow opal with dark greenish inclusions that resemble moss. Dendritic Opal may also be referred to as "moss opal" because of the tree-like appearance of the inclusions, or "dendrites", which comes from the Greek word, "dendron", meaning "tree".
Dendrites are fern-like inclusions of iron, manganese, or other metallic oxides that create bold patterns within the gem. Typically, dendritic opals are cut into slices 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. Usually these opals are white, yellow, blue, green or pink and show the black inclusions well.
These one of a kind cabochons hail from mines in western Australia.
