Natural opalite is a type of opal without any fire called potch. Natural opalite often has dendritic inclusions and is sometimes called moss opalite. The name moss opalite may come from the moss like appearance of the dendrites or because it is often associated with moss agate and plume agate. A dendrite is a branching treelike figure produced on or in a mineral by a foreign mineral. Opalite can be a variety of colors from yellow, green, brown, white, tan, and peach.
