Stilbite:
Stilbite is a mineral belonging to the zeolite group, widely found in various parts of the world. Its name is derived from the Greek word “stilbein,” meaning “to shine” or “to glitter.” Stilbite crystals are typically either transparent or translucent and can exhibit various colors, including white, yellow, pink, and brown.
There are two main varieties of Stilbite crystals known: Stilbite-Ca, which contains calcium, and Stilbite-Na, which contains sodium. These crystals often appear in needle-like or grouped shapes and are frequently found in areas where volcanic activity has occurred.
