My mineral collection part 7, Kyanite

in #photo6 years ago

Hello again, I know I haven't posted in a long time about my collection but I think I will redeem myself with this one.

This is the mineral kyanite one of the, if not the most beautiful mineral I have.

It belongs to a group of silicate minerals with the chemical formula Al2SiO5.
What determines which mineral it becomes is pressure and temperature indicated in the table down below :

It's gorgeous blue colour gives it its name the ancient Greek word kyanos means dark blue.

Another interesting thing is that it has different hardness depending on the axis 4.5 to 5 and 6.5 to 7 on Mohs scale.

Here are the rest of the photos but I am really bumped that they don't capture the full beauty of it.
