It it safe to Skype people from Minecraft?

My 9 year old brother (turning 10 next month) loves Minecraft and plays it everyday (if not everyday, then most days). He likes to play online and has made "online friends" on it, just people he plays with.

Anyway, there's this particular friend he's made on Minecraft that he's been asking to Skype with. There've only both shared with each other their first names and age (the person he plays with says she's 11/12).

Point is, is it safe to Skype with people you've never met in person? At school, I've heard plenty of things about cybersafety and all that, so I don't know whether he should Skype this person or not. I've read some places that it should be okay as long as you don't give out any personal/sensative information, but I just want to be certain.
