the answer is no.It will just turn normal again.
In Pokemon Platinum you can get it by going to the distortion world from Turnback Cave. In Pokemon Heartgold and Soulsilver, the only way to get it is to bring an event Arceus to the Ruins of Alph and trigger the event. Then, when you have to choose between Dialga, Palkia, and Giratina you must pick Giratina. Side note: You cannot trade the orb because if you have a Pokemon holding it while in the union room, it will instantly go back to your bag. The game creators did this because the griseous orb is not in Pokemon diamond or pearl.
Trade it to someone. It will evolve after the trade. This is with every Pokemon game. Others that do this are: Kadabra, Slobro(while holding King's Rock), Kingdra(while holding King's rock).
you must trade or migrate a magmar/magby from another DS Pokemon game or Pokemon ruby/sapp etc trade a magmar while it is holding a magmarizer for it to evolve into a magmortar
Trade onix while it is holding metal coat
You have to trade Electabuzz to someone while he/she is holding an Electrizer.
Giratina is not found through normal game play. You must have an Arceus from the Arceus event that took place a while ago to get Giratina.
In Pokemon Diamond and Pearl, Giratina can be caught in Turnback Cave in Sendoff Spring, which is east of Route 214. In Pokemon Platinum, Giratina can be caught in its home world, the Distortion World. The event takes place on top of Mt. Coronet, similar to the Dialga/Palkia event in Pokemon Diamond and Pearl. In Pokemon Alpha Sapphire and Omega Ruby, Giratina can be found in a dark split in the sky while riding Latias/Latios with Dialga and Palkia in your Party. For the rest of the games, you will need to trade/transfer for it.

you trade clampearl while its holding a deepseascale
You DO NOT find Giratina in Pokemon Gold, which was made before Giratina. Pokemon is divided into generations (4 so far, 5th one coming out in Japan this year), and Giratina is a Generation IV Pokemon, while Gold is a Generation II game. However, if you mean HeartGold- that's easy, just trade with Pokemon Diamond, Pearl, or Platinum, where it can be caught, or any other compatible Generation IV or above game which has the Pokemon.
The orb that makes Giratina Sky form is only obtainable through the Arceus event. You can't trade Giratina while Hes holding the orb So that's the only way to get him
