one word of caution about bone and antler in piercings i have something in the back of my head that says this is not good practice i can't quantify this but pumbaa please check this out if my niggle is correct you can get some very nasty infections this way be careful mate.
ooh just a though but I've seen fake ivory i.e. plastic that looks like ivory maybe this would be a better (safer) bet.
Yeah, I'd like to second that - you'll need to polish it to a VERY fine finish and then disinfect etc. I wouldn't use antler, personally, but I know that buffalo horn is used... my concern about antler would be the porous stuff in the middle, it's probably great at soaking up germs - and holding them.
If you don't mind going for an imitation, it'd probably be safer, but I'd personally understand you wanting one made out of horn. More satisfying
Just be really careful... make sure you clean everything well, and hopefully it'll be OK. Although you really shouldn't take my word for it; my solution to stop my piercings getting infected was to take them all out
Several months for my nose and about a month for my lip and they're still not closed completely....
