Quality｜Violentite. Aquamarine quality｜This Violentite is recommended for those who like it! Iolite from Tanzania. It is a coincidence that the mining site of Tanzanite is in the same area as Tanzanite.

Gem-grade Violentite crystals will appear transparent under certain light angles. From the photo, you can see that part of the gem is "invisible". When this Violentite is illuminated by light, the light reflected by the crystal into the eye will really give you the illusion of the velvety blue of Kashmir sapphire if you don't think carefully. No wonder ancient Westerners called Violentite "the poor man's sapphire". I think the reason is because the color of Violentite is often more like the color of sapphire than sapphire!
