Description

This is in my evaluation the very best quality for Analcime world-wide. The discovery is not very prominent, although there is nothing in compare-able quality from any other locality. The crystals fro Fendjiashan show glassy character - not even material from Quebec shows this quality! The crystal of this particular specimen is much better in person - it is transparent, not opac or white - you can´t see this on the photo very well. The termination is razor-sharp all around - back-side is complete and all faces show excellent luster. The crystal is over 2cm across, set on matrix and very aesthetic. This stuff is very hard to obtain - quantity was low and nothing came out since several years.
