This cabinet specimen shows a variety of zeolite minerals that can be found at the famous localities in India. The most notable, however, are several large Gyrolite nodules that rest on the basalt base. These nodules reach nearly 0.4" (1 cm) in diameter and are generally in excellent condition. No actual crystals are visible, as all have aggregated into the round nodules. Their surfaces, however, show evidence of the Gyrolite's triclinic form. All have a dull, olive-green color and a dull luster, and are dimly translucent at best. They are accompanied by many smaller, milky-white prehnite nodules, a few incomplete, decaying laumontite crystals, a single okenite spray, and countless tiny quartz crystals that rest on the white chalcedony crust which covers the basalt base.
