This mine has produced countless specimens over the years, the vast majority are commercial grade, but every couple years a particularly good pocket is unearthed-- this is one of those better discoveries.

There is a crack through the specimen that has been stabilized, this is only visible from the bottom of the piece. 

One of the major problems with the epidote-prehnite specimens tends to be damage.  Unfortunately, stilbite is softer than either of those minerals, and they receive pretty much the same treatment, meaning that they rarely escape undamaged.  I looked through a large lot of this material, and selected a few clean samples to offer on the website-- after all, stilbite may be viewed as a common mineral thanks to the massive production from India and (to a lesser extent) New Jersey, but how often do you see a zeolite of any kind from anywhere on the African continent?

This could probably be trimmed into a top thumbnail example of an African zeolite, but I'm leaving it as is.
