Iolite

According to legend, Vikings used iolite slices to reduce glare when checking the sun’s position.

BRIEF INTRO

In legends, ancient Viking navigators used thin slices of iolite as filters to help locate the sun on cloudy days. Whether or not the tales are true, iolite (mineralogists call it cordierite) can be fashioned into beautiful gems. Strongly pleochroic iolite has been incorrectly called “water sapphire,” as it can display a blue to violet hue in one direction and pale yellow to colorless in another.

IOS

Iolite’s name is from the Greek word ios, meaning violet.

PLEOCHROIC

When you turn iolite, you’ll see three distinct colors in three crystal directions.

AU NATURAL

Iolite is not typically treated. This is an attractive selling point for some consumers.

TREATMENTS

There are processes used to alter the color, apparent clarity, or improve the durability of gems. Some gemstones have synthetic counterparts that have essentially the same chemical, physical, and optical properties, but are grown by man in a laboratory.
