Narcissa Malfoy's wand

"How dare you take a witch's wand?"

The wand of Narcissa Malfoy was of an unknown length wood and core materials.

History

In 1998, Narcissa gave her wand to her son Draco after his own was taken by Harry Potter during a skirmish in Malfoy Manor. It is unknown if Narcissa used another wand during this time.^[1] Draco lost it in the Room of Requirement while fighting Harry for Rowena Ravenclaw's Diadem, and it was subsequently destroyed when Vincent Crabbe unleashed Fiendfyre in the room.

She presumably purchased it around 1966 when she was eleven years old at Ollivanders in Diagon Alley when she first attended Hogwarts School of Witchcraft and Wizardry.^[2]
Other than the handles, Narcissa's wand design resembles Lucius Malfoy's wand in the film adaptations.
This wand also has a slightly different look in the handle in the film adaptations than the design of the Noble Collection replica.

In Harry Potter and the Deathly Hallows: Part 2, Draco Malfoy uses his mother's wand during the Battle of Hogwarts, despite being taken away by Dobby in Deathly Hallows: Part 1. It is possible that Dobby dropped it while appparating.
In Part 2 of the final film, Narcissa is seen holding another wand. It is unknown if it is her new wand or a temporary wand.
In Part 2 of the final film, her wand is shown to look like the Noble Collection Wand except that it didn't have the tiny white studs on the handle.

↑ Her birth date was given as 1955 on the Black family tree, meaning she must have started at Hogwarts in 1966 or 1967.
