If by badge you mean Gym badges, they:
- Help raise the stats of your Pokemon
- Make high-level Pokemon and traded Pokemon obey you
- Let you challenge the Elite Four (if you have all eight)
The 8th Badge in Pokemon Diamond is called The Beacon Badge.
Strength, which let's you move boulders around
First of all, badges get you into the Pokemon league. The coal badge in paticular, lets you use HM rock smash outside of battle.

In Diamond, Badge 5 can be gotten by defeating Fantina in her Gym in Hearthome City.
You get HM strength in the lost tower, which can be found south of Solaceon Town. Talk to an old lady in the 5th floor and she'll give the HM strength. But be4 you can use it, you must have the sixth gym badge, the canalave badge. Hope this helps.
