Description

This one will delight the zeolite collector. Here is an amazing piece of almost solid natrolite ! The specimen features a mass of white acicular crystals that form on a thin plate of weathered brown basalt. It forms larger radiating crystals in hollows and cavities. I have never seen such a large solid specimen of natrolite as this.
