Prehnite is a newly-found semi-precious stone. It was first described in 1788 and named for Colonel Hendrik Von Prehn (1733–1785), commander of the military forces of the Dutch colony at the Cape of Good Hope. The beauty of this stone is its semi-transparent green colour, which makes it looks like high-quality jade.
