Description

Spectacular group of blue sodalite crystals on matrix of analcime, found personally in one of my trips in 1990 to this world-wide Canadian site. Sodalite is a common mineral, but the crystals of this deposit are extraordinary and rarely seen, these specimens are usually fluorescent in long wave with an orange color not so much the blue crystals but the accompanying crystallizations of gray color.
