Red stilbite is not a mineral that we know too much about but having seen this superb piece at one of our suppliers in South Africa, it immediately attracted our attention hence we chose it for our collection.
The origins of the name stilbite comes from the Greek word meaning "to shine" and relate to its vitreous to pearly lustre. Lustre is a term that describes the way that light interacts with a mineral. Stilbite which can be translucent to transparent occurs in several different colours.
Although we've had red stilbite in our collection before, it has always been within apophyllite so this is the first time that we've had such a large piece of red stilbite and the first time that it's not been part of another mineral.
Relatively soft, red stilbite is graded 3½ to 4 on Mohs scale of mineral hardness and its availability is considered to be widespread.
