Blue Peruvian Opal, also called Andean Opal, is a relatively new material and is characterized by the remarkable blue color. This is common opal (lacks the flashy fire of precious opal) and shows a glowing opalescence created from the deposited silicate minerals during formation. The solid blue material will make impressive gemmy cabs, however,  some pieces of the Caribbean blue are offset with white, black and brown accents creating fantastic seascapes. This opal takes a superb polish and will make impressive finished pieces.
