Dendritic opal is a type of opal that consists of dendrites, which are fern-like hair thin inclusions of iron, manganese, or other metallic oxides that create bold patterns within the gem. The opal itself is a striking while the inclusions tend to appear to be blueish black to a dark grey hue. 

Traditionally, dendritic opal has been associated with love and luck.
