Analcime is a rare zeolite sometimes found associated with Brandberg specimens. On this specimen the analcime looks like glistening dew covering the specimen.

A good specimen from every aspect.

The color of the prehnite is a richer green than is seen in the pictures. Seems my digital camera makes greens seem much more washed out. I have a similar problem photographing fluorites and dioptase.

Chemical Composition: Ca2 Al2 Si3 O10

This specimen is from the Gobobos Mountains, Brandberg, Namibia.
