Epistilbite is a hydrous calcium aluminosilcate, and a member of the zeolite group (Coombs et al., 1997). Rose (1826) differentiated this species from stilbite with careful goniometric measurements; the mineral name combines Greek root epi, near, with the mineral name stilbite.

Epistilbite forms a cluster of pink crystals, 1.7 cm across, in a quartz lined cavity in basalt. The epistilbite crystals have a pink tinge, likely form hematite. Local diggers carve these specimen out of hard matrix, leaving a rounded back. Attractive. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona.
