Description

You can find several zeolite specimen in this auction and yes of course stilbite from India is larger, has more color and more impressive dimensions, but this material from Iceland is so much more rare. While ago I bought a small collection from a guy who collected minerals from Iceland over 40 years, but on the common market you will not find any material from these rare localities. The particular specimen is snowy white, glossy, developed as floater and undamaged.
