04-25. Garnet #3.
What more to say!
The structure of this garnet crystal is so awesome, I just highlighted a few spots here and there.
Now, the most surprising for me is that antic and medieval jewelry takes so much after the geometry of the crystal, I wonder how they did it, not having any of the sophisticated instruments we have today to study nano-size objects.
There are 365 atoms, 642 bonds, 107 polyhedra in this image – not counting the few gems I inserted on the original geometry.
