The most notable wands within the Harry Potter series are the wands owned by Harry Potter and Lord Voldemort, which both contain the tail feather of the phoenix owned by Albus Dumbledore. The most important wand within the series is the Elder wand, one of the Deathly Hallows.
Much emphasis is made of the wands of Harry and Voldemort sharing the phoenix tail feather core. While the cores of the wands is the same, the wand that chose Harry is made of holly, while the one that chose Voldemort is made of yew.
The most powerful wand within the series is the Elder wand, one of the Deathly Hallows, owned by Albus Dumbledore and then by Harry. Harry uses the Elder wand to repair his broken wand and then returns the Elder wand to it's final resting place.
Others include Fleur Delacour's, which features a core of Veela hair from her grandmother, and Bellatrix Lestrange's wand, which was possibly crafted by Garrick Ollivander himself.
