Kornerupine is a tiny and very rare mineral first identified in SouthWest Greenland in the late 1800s. Some have been found since in Kenya, Australia, and Myanmar, Tanzania, and Madagascar. This mineral is transparent to green-yellow and comes in long orthorhombic prisms. Its symmetry is Cmcm – no rotations and reflection axes parallel – a type of symmetry found in Assyria and ancient Egypt design and also at the Alhambra in Spain.

Kornerupine in a box!
Yes, that’s the way it came up today in the VESTA software. What an amazing little crystal – after a glorious week of celebrating symmetry, balance, and harmony, its atoms just went back quietly into their original unit cell and left in the market place the outline of a very pleasant 3D abstract sculpture.
Thanks for the show – Kornerupine!
