Description

A good specimen of crystalline mesolite from a new find. The only time in the past I have come across examples of this quality from the locality was 18 yrs ago. It is almost entirely comprised of radiating crystals which are compacted into a snow white, coconut like, mass near the focus. In the outer sections the radiations show fine mesolite needles. The terminations themselves are transparant when observed with magnification. It could be another 18 yrs before material like this emerges from the locality basalts.
