(Ca,Fe,Y,Th)(Nb,Ti,Ta,Zr)O4


Black colored crystals of Polymignite in a Quartz matrix. There is one well formed crystal on the edge of the specimen. Polymignite is now considered a variety of Zirconolite which is a bit poblematic because Polymignite was first described in 1829 and Zirconolite was not described until 1956. Yet Polymingite was discredited in 1989.

Condition: Fairly Good

Flaws: Only one of the crystals is intact and is not complete.
