Put together a basket of condoms, semen "killer", etc. Maybe add in a nice little vibe and send it to her or have it sent to her work, house, or just put it at her doorstep. Maybe have a little card that says "be careful." Be friendly about it or you could even make it humorous? I don't know. If she's educated and still behaving ignorantly, then there's nothing YOU can do about it really. Definitely try to say or do SOMETHING though. Here's what I'd do if it were my best girl friend: I'd dicreetly bring up the topic of sex, or sexual partners, acting like I'm telling her something confident like "my partner and I enjoy doing it without a condom, but I could never do it without protection if I didn't know him." Of course I'd make it believable, but something like that usually does the trick with my close girl friends.

Is there something else deeper going on? Perhaps she is engaging in this behavior as a cry for help or perhaps she feels that she doesn't need protection or isn't worth saving. Or she may be suffering from self esteem or family pressure that make her feel like her health is unimportant. I'm not a therapist, but it sounds that something deeper could be going on here.

I would be there, and would try my best to make the conversation light at best. Always say you are there and care. I do love Kendra's idea of a gift basket.

Also... is she on pills or something against pregnancy? Because if she's not, that's a whole other host of issues as well.

I wish you luck. I have had friends go through similar things, so if you want to message me, I'm more than happy to listen. Hope it gets better.

Everyone else has already said everything I could think of! Good luck!!
