Don't pay attention to the stupid answer above, just level it up in the night.
Eevee doesn't evolve into Umbreon with a stone. Eevee evolves into Umbreon when it is levelled up with high happiness during the night.
You can't make eevee evolve into espeon by leveling it up. You have to give it a certain stone. I think it might be a moonstone, but maybe that makes eevee evolve into umbreon.
Evee can evolve by using a water stone to evolve into vaporeon, using a thunderstone makes it a jolteon, using a fire stone makes it a flareon. Now you can get espeon and umbreon in the game but its completely random. Just have the evee love you and level it up and it will evolve to espeon or umbreon and like i said its random. If you want espeon and umbreon the easiest way is to get them from ruby or sapphire or emerald or even Pokemon colosseum or even Pokemon xd gale of darkness.In Pokémon FireRed, Eevee can evolve at any level because Eevee can evolve into only 1 of 3 Pokémon in Pokémon FireRed. Eevee can evolve into a Vaporeon if you use a Water Stone on it, if you use a Thunderstone on it then it'll evolve into a Jolteon and if you use a Fire Stone on it then it'll evolve into a Flareon.
No, you cannot do so in LeafGreen. While Eevee can normally evolve into Espeon and Umbreon without stones, the lack of a time system in the game prevents Eevee from evolving into one of them.
in Pokemon red, blue, and yellow, you can evolve eevee into flareon, vaporeon, or jolteon, by using on it a fire stone, water stone, or thunder stone respectively. In Pokemon gold silver and crystal, eevee can evolve into the three previous forms mentioned, as well as: umbreon and espeon by leveling up a happy eevee in the evening, or in the daytime respectively.

Use a moon stone on Eevee.

yes you have to use a dark type stone! Don't listen to him^^^ he surely doesn't know his Pokemon if he thinks you can evolve eevee to umbreon with a stone. You got to train eevee at night only.Then when you are close friends with it, it'll evolve
You don't use a stone at all. Eevee evolves into Umbreon via happiness, followed by a level up AT NIGHT.
You get a dark stone and give it to the eevee and raise its happiness and leave it up all night.
In Pokémon Conquest, there is no evolution stone or evolution related item that you will need in order to evolve Eevee into Umbreon instead you will need to have at least a 70+% Link level and then you will need to head to the Kingdom that is called "Yaksa" and you will need to find something that you can accomplish there and then your Eevee will evolve to Umbreon.
Because Eevee evolves into Umbreon only by maxing out it's happiness during the night and leveling it up.

usually by happiness at night but what i do is give it a moon stone to hold then level it up once. trust me i tried it multiple times and it works
You don't. :) Eevees don't evolve with a dusk stone. They only evolve with a fire stone, water stone, and thunder stone.
