About the Gemstone Iolite


Iolite is the gemstone variety of the mineral cordierite.  A translucent stone with a distinctive bluish violet colour, it's often compared to sapphire but is slightly more purple.  One of its most notable characteristics is pleochroism which is an optical phenomenon that enables a crystal to exhibit different colours when viewed from different angles.  Depending on the type of light and angle from which the stone is being viewed, it can appear to be blue or a subtle shade of violet but as its rotated the colour changes to yellowish grey to light blue.

The name iolite comes from the Greek word 'ios' meaning violet whilst cordierite was named after the French geologist Pierre Louis Antoine Cordier who first described the mineral in 1809.  It was officially classified and named as iolite in 1813 but is believed to have been known and used as a gemstone in Sri Lanka long before that.  

Although many other gemstones are pleochroic, unlike iolite most have such minimal colour change that it's almost unnoticeable.  Cordierite and tanzanite are the two main minerals which exhibit pleochroism with colour change that can be easily seen.  Although two completely different minerals, iolite can sometimes be confused for tanzanite which is the gemstone variety of the mineral zoisite.  Although their optical characteristics are similar, tanzanite is much rarer and considerably more expensive.

 

 

More Facts about Iolite


The finest iolite crystals come from from India, Brazil, Sri Lanka, Mozambique, Zimbabwe, Madagascar and Myanmar.  It's widely believed it was also mined by the Vikings in Norway and Greenland.  More recently in 1996 an iolite deposit was found in Wyoming in the USA and further discoveries were made in 2004 and 2005.

In crystal healing iolite is used to clear thoughts, it opens intuition and aids in understanding and releasing the causes of addiction as well as helping one to express their true self.  It releases discord within relationships and encourages taking responsibility for oneself overcoming codependency within a partnership.

Graded 7 to 7½ on Mohs scale of mineral hardness means iolite is relatively hard which makes it a particularly suitable stone to facet.
