Sitting on the desk, Susan's horn looks like it has been carved from ivory. On picking it up, however, it feels very much like the urethane prop it is.

Paul Tobin and Christian Pearce, two designers from the Weta Workshop, created many of the children's gifts for The Chronicles of Narnia: The Lion the Witch and the Wardrobe, including Susan's horn which then re-appeared in The Chronicles of Narnia: Prince Caspian. The concept behind this horn was that it should look as if it were a pair with Susan's other gifts, the quiver and the bow. They decided the design should indicate that they were all carved from the same ivory tusk and when slung on her back, become one unit. The very tip has a mother of pearl inlay while the horn itself is carved in Aslan's likeness.
