Newton Scamander's wand

Newton Scamander's wand was of unknown length, made of lime (Also said to be made of ash .), and contained elements of bone core, along with shell which was placed in the end of the wand. It has something carved into the end that slips into his hand when he holds it.

Behind the scenes

 * So far, Newt's wand is the only wand in canon with a core made from multiple animal-derived materials.
 * Eddie Redmayne chose the wand from a number of designs made by Stuart Craig. He loved that it was very simple, and made of organic materials including some fossilised pieces. He thought it was suitable for Newt and his love of creatures. It was also made of timber, which Eddie liked because it looked like it was "whittled". It has something carved into the end that slips into Eddie's hand when he holds it.
 * Both this wand and Queenie Goldstein's wand were used to conjure a transparent umbrella from the wand tip in Fantastic Beasts and Where to Find Them.
