- Prehnite on Quartz
- Miniature, 4.6 x 4.4 x 3.0 cm
- Brandberg, Namibia
- Ex. Charlie Key
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 3 cm, translucent, pear-green ball on matrix just blows me away! It has to be one of the most aesthetic prehnites I have seen, in this size!
