Hau night

Hauinite has an impressive bright cobalt blue color. It is also known as one of the minerals that make up lapis lazuli. Because its production areas are limited and large grains are difficult to harvest, it is highly valued as a rarity. Some of them even fluoresce under ultraviolet light.
