Here is a good example of the rare mineral fahlunite: (Mg,Fe)Al2Si3O10 · 2H2O.  The fahlunite is a replacement pseudomorph after iolite.  This specimen comes from a discovery I made in Connecticut in the early 1990s, but I only recently was able to identify it.  The color is an attractive steel blue, with a slightly metallic luster.  The pegmatitic matrix includes smoky quartz, feldspar and schorl tourmaline.
