Give me back my wand! Give it back to me!. Hermione Granger's wand was 10Â¾ long, made of vine wood, and possessed a dragon heartstring core. The wand was manufactured by Garrick Ollivander sometime before Hermione's education at Hogwarts School of Witchcraft and Wizardry.
J. K. Rowling used a Celtic calendar to assign Hermione's wand wood based on her date of birth, as vine corresponds to those born between 2 September and 29 September. She did the same for Harry's wand and Ron's wand, as a hidden connection between the three friends.
