I reponded to this on the Pi Phi page also.
If your friend is a Pi Phi, she should already have this pin. This is the pin we receive when we are intitated. So unless she lost hers...
You can also purchase a brand new one for only $5 more at
http://www.pibetaphi.org/market/mktfram.htm, or spend a little extra and get one with jewels.
