you can't get it in diamond you can only get it in platinum
You cannot get the Griseous orb in Pokemon Diamond. You can only get it in Platinum, Heartgold, and Soulsilver and it is untradeable
To get the gresious orb i pokemon platinum you have to go back into the distortion world. to get to the distortion world the second time go back to the spring path and into turn back cave. You have to see 3 pillars with only going through 30 rooms. Then if you did not catch giratina the first time he will also be there and you will have to battle him. The distortion world the second time through is sj=horter and is a one way path so it will be very easy to get the gresious orb it will be in a pokeball on the ground. When you give it ti giratina he will change into his sky form like with shaymin and the gracideas.
The Griseous Orb is only available in Pokemon Platinum.
There's no way you can. It disppears when you trade the Giratina holding it. there is no platinum,pearl,or diamond orb its called the GRISEOUS orb,adamant orb and lustrous orb
beat the elite four 2 times and go to abbysial ruins and compleate it.after that if you have gresious orb,admant orb,lusterous orb go to nimbasa city and go to lostlorn forest with zoroark first pokemon or victine given from event.leave it the first pokemon in the party you will encounter arceus
you get it in the back of the spear piller with the chip Pokemon diamond so you have to get diamond version dialga is the one to be held of the adamant orb.
There is not such item called "black steel orb".
In sendoff spring
Giratina is in Turnback Cave if you have Diamond or Pearl. If you’ve already captured him in Platinum, you’ll find a Gresious Orb. It will change Giratina into his origin form if you make him hold it, and it also boosts the power of Ghost and Dragon moves.
The griseous orb cannot be gotten in diamond. it's a platinum exclusive.
if you mean the orb palkia uses you cant get it unless you trade
first thing you need to do is beat the elite four, then go to turn back cave and keep walking threw doorways until you see this portal with a rare bone above it. go in the portal and walk to the end of the distorotion world and you will find the platinum orb to the right. It gives girantina to transform into its origin form(has better stats then altered) PS: this item is not called the platinum orb. it is called the gresious orb( i have the English version and it was the gresious orb. people just think it is called the platinum orb because the game was called Pokemon platinum.
