Britholite-(Ce) / Allanite-(Ce) on Microcline October birthstone It should be noted thatA rich specimen, and a great representation of this extremely hard to find material. This specimen was personally collected by my father, Richard Kosnar, on April 15, 1973. It features brownish areas of the uncommon phosphate, Britholite (Ce) associated with greenish grey Trnebohmite (Ce) which are covered on one side by a dark band of Allanite (Ce) with so called pinkish tan Cerite and pinkish Microcline. The specimen was analyzed by Gene Foord years
