IOLITE

"Violet" stone
Iolite can have many inclusions. THE MOST UNCOMMON STONES ARE STONES WITH MICA OR HEMATITE INCLUSIONS. FROM ONE ANGLE THEY LOOK LIKE BLACK DOTS, BUT, SUCCESSFULLY CATCHING THE LIGHT, YOU CAN SEE HOW THEY FLASH WITH SILVER LIGHT AND THE STONE BECOMES LIKE A STARRY SKY.
Steingelite, cordierite, Spanish lazulite, dichroite, lynx sapphire, water sapphire. It seems that iolite, by the number of synonymous names, occupies almost the first place in the list of jewelry stones, and this despite the fact that this mineral has no varieties and "close relatives".

Iolite has a complex chemical composition, being an aluminosilicate of magnesium and iron. The color of iolite is not typical, perhaps, for any other stone, and perhaps amethyst or sapphire can sometimes have a similar violet hue. At the same time, iolite has one amazing property that will always make it possible to distinguish it from other minerals, as well as fakes and imitations - a pronounced dichroism - a change in color intensity with a change in the angle of inclination of the stone to the light.
Due to this remarkable property, iolite has long been used by navigators to determine the position of the Sun in overcast skies. Hence one more of its names - "Varangian stone". In aviation, iolite is an integral part of polarizing filters used to determine the position of the Sun after sunset (based on the change in blue polarization depending on the direction of observation), allowing you to determine the position with an accuracy of 2.5 °, even if it is 7 ° below the horizon line.

In iolites, as in many other minerals, inclusions form often. But it is inclusions of hematite and mica that are the most beautiful (and the most common), since when light hits them, an incredible effect of the night sky strewn with stars is created in the stone.

It is believed that iolite dissolves the fear of the unknown, helps to neutralize the depressed state of the psyche. In difficult situations, it helps to make a decision, even if it seems that there is no way out.

Iolite helps in restoring balance and is recommended for people suffering from disorientation, lack of motivation, chronic disorganization and inability to concentrate. It strengthens the determination to take responsibility and carry it to the end, and provides confidence and resilience in adverse situations.

If you put jewelry with iolite at a head of a bed at night, this will help a person suffering from insomnia to fall asleep quickly. But it is not exactly.

It is also recommended to look at the stone every day for 10-15 minutes, admiring the play of color on its faces in a light of electric rays. Such an exercise should help relieve excessive nervous tension, get rid of unreasonable fears and obsessions.
