The Belt of Venus is actually the Earth's own shadow cast in the sky. As you probably already know, the bright blue of the daytime sky is due to light from the Sun being scattered by dust in the atmosphere. When you take away that light from the Sun, what you're left with is a dark sky. The Belt of Venus appears on the Eastern horizon just after the Sun is sets in the West because the sunlight doesn't reach the Eastern horizon at that time. This is also why I suspect I haven't ever seen it previously - too high a horizon all around me where I live.

The belt of Venus is the pink band you sometimes see across the sky at dawn and dusk.
The Belt of Venus is caused by a preferential increase in refraction by the atmosphere, under certain atmospheric conditions, of the frequencies make up that specific shade of pink.
To say that it's the "earth's shadow" is to oversimplify to such a degree that you throw away the entire problem.
