In Pokemon Diamond how do you get a duskstone. I need one to evolve my Murkrow.?

Answer 1

s5.8.2. Veilstone City |_________________________________________________)

Back in Veilstone City, head on over to the giant black building in the
northeast corner of town. That's the Veilstone Galactic Building, and right
now, you're out of luck, because there's no way to get past the locked door
that's inside. However, there's a clumsy Team Galactic member outside of the
building who will drop the Storage Key after you speak with him. Pick it up,
and then go back to where you and Dawn battled two Galactic Grunts and where
you got HM02 (Fly) (it's in the northwest corner of town). Yep, the Warehouse.

Go inside of the Warehouse, and then open the door with your Storage Key
(simply press A on the door and select "Yes"). Grab the Dusk Stone, and then
head into the basement of the Galactic Veilstone Building.
