What is Iolite
Iolite is a gemstone of silicate mineral variety cordierite. It is made up of the chemical elements magnesium, iron, and aluminum. Iolite is known as cordierite (named after the French geologist Pierre Cordier who first studied it) in mineralogy.
In gemology, cordierite trades as iolite which was named from the Greek words “ios” and “lithos” meaning violet stone. Another older name given to iolite is dichroite which means two-colored rock in Greek. This is in reference to the pleochroic nature of iolite gemstones.
Iolite is a fairly durable gemstone, rating 7-7.5 on the Mohs hardness scale. However, it is not as durable as sapphires, topaz, and diamonds. When set in jewelry that is high impact like rings and bracelets, special care should be taken to prevent damage to the stone.
What does Iolite look like
Iolite is a violet-blue to gray, yellow, or colorless gemstone with a vitreous luster. It is a pleochroic gem which means that it displays different colors when viewed from different angles. Iolites that appear violet or blue in color from one angle often display yellow, gray, colorless, light, or dark violet pleochroic colors from another angle. The presence of iron in the mineral structure of Iolite gives it a gorgeous blue hue. Inclusions in the iolite gemstones lead to attractive cat-eye or aventuresence effects.
Fine iolite is known for its naturally beautiful blue and violet hues. Unlike blue topaz, sapphire, and tanzanite which are often treated in some way, iolite is not usually treated. Some iolite gemstones also appear gray or colorless and if gemologists were able to enhance them to produce more brilliant hues then they certainly would do so. The chemistry of iolite however doesn’t allow it to be treated as it cannot tolerate high temperatures.
The value of Iolite
The value of iolite has not been developed in the gem trade, therefore its price is low. You should consider the 4 C’s when picking out the best iolite to add to your gemstone collection.
Carat
Iolites range in size from 1 to 10 carats. Fine iolites over 5 carats are somewhat rare in the market. Most iolites are 2 carats or smaller.
Color
Iolites are often used as blue gem substitutes and rival the allure of tanzanite and blue sapphires at a fraction of the cost. The most desirable colors of iolite are violet-blue to fine blue.
Clarity
Iolite is transparent to translucent with relatively few inclusions. Those iolite gemstones that do contain inclusions are seen as different types of iolite such as cat’s-eye iolite or bloodshot iolite.
Cut
Iolite is cut to highlight the transparency of the gem, therefore it is most often faceted. Its highly pleochroic nature makes it a tricky gem to cut to bring out its most suitable color. Iolites are also cut into cabochons and sometimes made into carvings. Lower quality iolites are cut into beads.
History and mythology of Iolite
Iolite was once known as the Viking’s Compass stone. It was used to guide Viking navigators by helping them locate the sun, which they used to steer their ships. They were able to pinpoint their location by finding the sun using slices of iolite on glare-reducing polaroid lenses on a cloudy day.
Iolite was widely used in jewelry pieces during the 1700s in Europe. Spiritual healers used iolite in rituals and ceremonies across all cultures. They were said to bring about visions and allow shamans to communicate with the spiritual realm.
One of the largest iolite crystals was discovered in Grizzly Creek, Wyoming in 2004, and weighed a record-breaking 24,000 carats.
