A diverging spray of gemmy, lustrous natrolite set aesthetically in a completely hollow basalt vug from Jalgaon. The crystals reach 3.5 inches long and emanate from a druse of sugary white chalcedony.

A few natrolite crystals span the vug and attach to its ceiling, but most are visibly terminated. Natrolite is uncommon from the Indian basalts, where the great majority of needle-like zeolites are the related species scolecite, so well-formed natrolite sprays are worth noting.

An attractive, well-preserved vug specimen for zeolite collectors.
