Welcome to Benitoite!

Here you are, in the middle of San Benito Mountains in California, with James M. Couch, in the year of 1907, and you found a new rare mineral composed of barium, titanium, and silicates. It was formed a long time ago in conditions of low temperature and high pressure, which is typical for subduction zones at convergent plate boundaries. Its colour is blue, and it fluoresces under short wave UV light. But you don’t want to read a geology paper, right?
You want to knit this blue-metallic top-down crescent shawl!
