Allanite-(Ce) from Chibiny, Kola, Russia– miniature specimen as unique piece
This miniature specimen displays a contrasting formation of Allanit-(Ce) in black to dark green coloration within a light matrix. The piece appears compact overall, with dense, embedded zones of this rare cerium-bearing silicate. The dark sections stand out clearly from the host rock, suggesting an intense mineral intergrowth.
Allanit-(Ce) is a cerium-rich silicate from the epidote group, typically formed under metasomatic conditions. It occurs in granites, pegmatites, and metamorphic rocks and is an indicator for rare earth elements. While geologically widespread, attractive or collector-grade specimens are limited to a few localities.
Geology & Origin:
The Khibiny Massif on Russia’s Kola Peninsula is one of the world's most important localities for rare silicates and REE minerals. This alkaline rock complex is rich in pegmatites and metasomatic zones, where minerals like Allanit-(Ce) form. Specimens from Khibiny are especially valued by collectors for their mineralogical diversity and scientific importance.
