Growing on a sliver of matrix, are two, large, blocky, crystals of glassy, bi-colored, fluorapophyllite, the largest of which is 7.0 cm in length. For aesthetics, the two crystals form a near perfect "V" and there are also pearlescent, 2.0 cm across stilbite crystals scattered on the fluorapophyllite crystals. A very showy and aesthetic piece!
