Prehnite
It is named in honor of Hendrik von Prehn, governor of the Cape of Good Hope (South Africa) in 1774 who discovered this mineral. The name was coined by the famous German geologist Gottlob Werner in 1788.
They usually appear in a botryoidal habit - globular external shape and resembling a bunch of grapes (where the name derives from the Greek).
