While natrolite is well known from other locations, it is not so common in India. When it does occur, it is white. This is a weird find, with a distinct green color thought to be caused by celadonite inclusions (though not proven so far as I know). It is a 1.6 x 1.4 x 1.1 cm green, spherical specimen composed of micro-prismatic crystals forming a ball shape.
