The Dark Stone is a key item in Pokémon White that contains Zekrom after it lost its physical form. In the final battle against N in his castle, the player will battle Zekrom and will get the option to put it directly in their party for the following battle against N. Its Pokémon Black counterpart is the Light Stone.
The Dark Stone returns in Pokemon Black 2, where N gives it to you after you defeat his Lvl 70 Zekrom, so you can take it to Dragonspiral Tower to reawaken it and catch it. It will still be at Lvl 70.
