iolite gem


Ancient Viking navigators used thin slices of iolite as filters to help locate the sun on cloudy days. Iolite seems appropriate to celebrate twenty-one years of marriage with all its ups and downs. Iolite is an affordable inky blue gem sometimes used to substitute tanzanite. It is pleochroic, which means it can display a blue to violet hue in one direction and pale yellow to colourless in another.
