I'm willing to agree that picturing a diamond from above not
necessarily is the best way to show off a diamond shape.
But the diamond shape is designed so that as much light
as possible is reflected out of the crown. And of course
people therefore prefer to have the diamond mounted with
the crown "up" in their jewellery.

The diamond cutters often try to cut the diamonds so that
it looses as little weight as possible to in order to get
high carat numbers.
This causes a lot of round brilliant diamonds to wary
quite much from the "ideal cut".
Here's a couple of pages that I found about diamond cuts:
