I bought my Hollowbody Spruce used, with a bone nut already added. The original nut was in the case. I have not swapped it back, and don't plan to. I guess the previous owner thought it was worth it.
Bone is normally brighter than graphite, and the strings don't move a smoothly over bone either. I think it's a step backward.

A properly cut and *lubed* bone nut, along with good tuners and trem, will stay in tune great.
Out of all of them, bone sounds most dead to me.
