You do not normally think of Prehnite in and of itself as a top class mineral specimen, because the crystals don't usually get big and isolated. Well, they do from here! This translucent, pear-green ball on matrix just blows me away! This is a very unusual, attractive, specimen, with the Prehnite growing in bladed, lustrous, tabular crystals. These in turn have taken on a radial form to produce a sphere 4 cm across. So unusual, so interesting, this has to be one of the more aesthetic Prehnites I have seen, in this size!
