I am very sorry, it is a beautiful chair.
Though you probably right he broke it, you are a business so you have to deal with this from a business point of view.
1. I am assuming the Guest broke, I could be wrong,
2, Guest states he didn't break. I have no reason to say the Guest is a liar.
3. I am assuming it can't be repaired. I have a good photo. take some time and have furniture repairmen look at the photo.
4. Then make an educated business decision using information you receive from an experienced furniture expert.
