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.
Rowling has also revealed that she discovered that Harry's wand wood corresponded to his date of birth in the Celtic tree calendar afterwards, and decided to use the calendar to assign the wand woods of Ron Weasley and Hermione Granger as a hidden connection between the three.
