Why not about the staff? I presume that if Galadriel gave him clothing, then she gave him his staff too...
And when doing it, she could have possibly used the White Ring... As she did when she made Frodo's phial, she used the power of her ring to make a greater object. Gandalfs staff and Frodos phial have a similar effect: shining light...
