Complete, radial aggregates of white epistilbite on a basalt matrix lined with black chalcedony, a rare find for zeolite collectors. Every aggregate on the piece is undamaged, and the bright white epistilbite stands out sharply against the dark background.

Epistilbite is an uncommon zeolite. Crystals from most localities outside India are small, and the finest examples of the species are generally considered to come from the Deccan Traps. This small cabinet specimen offers clean, well-formed epistilbite in an attractive, high-contrast setting. Collected in 2021.
