This opal variety is termed “dendritic” due to it’s internal collection of dendrites. Dendrites is a Greek word for tree like. There are fern-like inclusions of iron, manganese, or other metallic oxides that create bold patterns within the gem. Typically, dentritic opals are cut into slices to best exhibit nature’s artwork. As you might guess, these pieces are one-of-a-kind, 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.

 Dendrite Opal is found in New Mexico USA & other countries including Australia, Brazil, China, India, Mexico, and Uraguay
