What was Luna's Lovegoood's two wands made of

This is a difficult one. It is possible that her original wand was mahogany and phoenix feather, 13.5 inches, but at no point is this confirmed.

I have a feeling either her or Ollivander might mention it in Deathly Hallows, either during or just after Malfoy Manor, but I don't have time to check right now.
