I would say so, since you need it to get Reshiram.
The sun stone is an item similar to the thunder stone, water stone, fire stone and leaf stone it evolves two pokemon: Gloom and Sunkern.
Once you have the item go to the bag and select the item using the A button choose the Pokemon that evolves by that particular item and then the evolution will begin. For example lets say you have an Evee and you have a water stone select the water stone and use it on Evee to make it become Vaporeon.
in Pokemon dimond its a shiny stone
Give it a mail item and trade it.
The Mist Stone was a fictional item thought up by fans during the Red/Blue days to explain a number of Pokemon that evolved from already fully-evolved Pokemon. There is no item by that name in any game so far. Are you perhaps thinking of a different item?
A Light Stone (or 'Dawn Stone', as it is known in the American localization of the games) is an evolution item used in the Pokémon series from the fourth generation onward. This sparkling item can be used on a male Kirlia to evolve it into Gallade, or on a female Snorunt to evolve it into Froslass.
The dawn stone is an item that is used to evolve certain Pokemon in Pokemon Diamond. To get this item, search in Mt. Coronet.
You cannot get that item in Pokemon Black.
The Oval Stone is an item in the Pokemon games which can be used to evolve certain Pokemon. For example, it can evolve Chansey.
