A curious specimen composed of several prismatic microcline crystals, some of them interpenetrated by something resembling a Carlsbad twin. They are partially coated by globular aggregates of opal, which fluoresce strongly under ultraviolet light. This specimen comes from the Peter Seroka collection and was acquired in 2007 from Allan Fraser.
