Jalgaon, Maharashtra, India
Thumbnail, 2.4 x 1.6 x 1.6 cm

Perched on a matrix of cm size stilbite crystals is a lustrous cluster of cavansite up to 2cm in length. This is, quite simply, one of the best cav thumbnails I have ever seen for condition and aesthetics; and also for the unique euhedral crystals that comprise it.
