No, a Water Stone will not stop a Pokémon from evolving. An item called an Everstone will stop Pokémon from evolving however Water Stones are used for evolving specific Pokémon. Water Stones can evolve Poliwhirl into Poliwrath, Shellder into Cloyster, Staryu into Starmie, Eevee into Vaporeon, Lombre into Ludicolo and Panpour into Simipour.
you use it on some water type Pokemon to evolve them. example:pikachu+thunder stone example:polywhirl+water stone example:evee+fire stone example:Roselia+sun Stone example:murkrow+dusk stone a ever stone prevents your Pokemon from evolving
Train them to a certain lvl and they'll evolve. A few needs a link trade for evolving and some can evolve by using a stone (like fire stone, water stone etc.)
The moon stone like other Pokemon games are used for evolving pokemon such as nidoran, nidorino, jigglypuff, Evee, ect some more.
some only evolve by using a evolving stone there's alot of those in pokemon platinum but you can only use the evolving stone on them when there a certain level or the best way train them faster cause them evolving doesn't make the, stronger just changes there look.
Here are SOME stones: dawn dusk leaf fire sun water oval stone everstone (prevents Pokemon from evolving) moon thunder these are all of the stones i know about.
Only one's I know of is Graveler, Magmar (With a Magmarizer), Machoke, Rhydon (With the protection item), Haunter, Dusclops (With Reaper Cloth). If you know anymore just edit this.
poliwhirl, evee and some others
i know these ones: thunderstone: pikachu >>>>> raichu eevee >>>>> jolteon water stone: lombre >>>>> ludicolo eevee >>>> vaporeon staryu>>>>starmie sun stone: sunkern >>>>> sunflora fire stone: vulpix >>>>> ninetales eevee >>>>> flareon growlithe >>> Arcanine moon stone: skitty >>>>> delicatty grass stone: gloom>>>>>vileplume& grass stone: nuzleaf>>>>> shiftry if you want an espeon you need to gain friendship with eevee and it will evolve into it and only if it is between 4:00am and 7:59pm, if it after 8pm it will evolve into an umbreon and gloom with a sunstone will evolve into a belossum. Of course some of these Pokemon can't be caught in emerald version and need to be traded over from fire red or leaf green version.
No, only some pokemon such as clefairy, evolve with a moon stone. But other certain pokemon will evolve only with a water stone or other type of stone. So a moon stone does not evolve any type of pokemon, unless that pokemon has the certain conditions to evolve.
an evoloution stone is a special stone that evolves some Pokemon. EG: eevee: use a water stone on it to evolve it into a vaporeon fire stone on it for a flareon thunder stone for a jolteon there are lots of Pokemon an evoloution stone can evolve types of stone: fire stone water stone thunder stone dusk stone leaf stone shiny stone dawn stone sun stone moon stone
I do not know all of them but hear are some evee=vaporion polywirl=polywrath
It depends on thew Pokemon. Most Pokemon evolve by gaining exp. Here are some Pokemon that evolve with a stone. Evee- can evolve into 7 different Pokemon depending on the stone Lombre- water stone pikachu- thunder stone there are many more
