Iolite is named after the Greek word “ios,” meaning violet. The rich purple to blue hues of iolite earned this gemstone the nickname of water sapphire. Only officially named in 1912, iolite still was loved and valued by cultures throughout history.
Iolite is sometimes referred to as the Viking’s compass. This gemstone is a light polarizer that helped Viking sailors navigate when the sun was hidden by clouds. An iolite lens enabled Vikings to determine the position of the sun even on overcast days, making it possible for them to navigate longer and further than before. While talismans of iolite were used for centuries, iolite became especially popular for jewelry purposes in Europe during the 18th Century. Iolite is the 21st wedding anniversary stone.💜💙💜
