iolite is not a well-known stone, its hardness—a
7-7.5 on the Mohs Scale—availability and pretty,
pale-blue color may lend to increasing popularity in years
to come. Until that time, iolite, which is gem-quality
cordierite, remains a lovely gemstone choice for people
looking for something out of the ordinary. One interesting
characteristic of iolite is its pleochroism. This relates
to the different colors that occur in different directions
of the crystal. This quality makes the work of cutting
iolite somewhat tricky. Look for the best-cut pieces with
good, light blue color.
