This combo specimen not only shows off the three species but also its formation in a basaltic vug. Light, emerald green, translucent, and lustrous fluorapophyllite, to 4.0 cm across, formed first. Then, came ivory colored, lustrous and translucent, epistilbite in spherical growth, measuring more than 5.0 cm across; at the same time as growth of pearlescent, lustrous, translucent, epistilbite crystals, measuring up to 2.0 cm in length. This is a zeolitic smorgasbord! The cluster is very bright and thought white, sparkles quite a bit.
