Stilbite is a variety of tectosilicate called a zeolite. These minerals are a special class where the structure of the crystal contains large, connected voids that form straw-like channels. Stilbite, like many zeolites, is found in cavities in basalt formations. The name stilbite comes from the Greek word stilbo or "luster" because of its pearly appearance.
