The vuggy basalt matrix of this specimen serves as host for an excellent small prismatic crystal of epistilbite. The cavity is lined with white drusy quartz. The epistilbite, a reddish-brown color, contrasts nicely with the quartz. The crystal is small, measuring only 0.1" (0.3cm). A loupe yields a good view of this monoclinic mineral. There is no visible damage to this specimen.
