Prehnite is a semi-brittle gemstone that most often forms as globules, stalactites, or in botryoidal growths. While not a zeolite itself, it is often found near zeolite deposits like heulandite or stilbite, and it was first found in what is now South Africa in the late 1700s.
Even more beautiful 'in person' - great.
