DescriptionStilbite is a silicate. Stilbite is also a common zeolite. Stilbite commonly forms crystals inside the petrified bubbles of volcanic rocks that have undergone a small amount of metamorphism. Stilbite crystals can aggregate together to form a structure resembling wheat sheafs. It has the chemical formula NaCa2Al5Si13O36·14H2O. Stilbite's name comes from the Greek stilbe meaning “luster” in allusion to the pearly to vitreous luster.
