For a sense of scale, remember that a diamond crystal large enough that you could see it with the naked eye would be assembled from approximately 50 million carbon atoms.
There is another way to visualize the relationship between the ball and spoke model of the diamond structure and the continuous surface of the filleted tunnel labyrinth, which is to say the Curved Space Diamond Structure.
This image shows the labyrinth geometry mapped directly by the ball and spoke model of the diamond structure. Here we see this relationship for the diamond unit cell.
Here we see the ball and spoke model assembly of eight unit cells.
The image below shows the ball and spoke model mapping the geometry of the diamond labyrinth comprised of eight unit cells. The ball and spoke model floats within the labyrinth.
