Description

A flattened, dark brown crystal of allanite-(Ce) from the super-classic talc mine on the French Pyrenees. Quite unusually the matrix is a terminated quartz crystal instead of ubiquituos dolomite.

Like most such specimens from Trimouns, the attribution to allanite-(Ce) is visual. Commonly, darker crystals are regarded as allanite-(Ce) and the lighter, pinkish ones as dissakisite-(Ce).
