What is the egg shaped silver pendant pregnant mothers wear for a healthy baby?

I've seen these on pregnant women in the past and they say it is for ensuring a healthy baby. We are now pregnant and I would like to purchase one for my wife to wear. Where do I purchase this? I think I heard I may find it in the Christian Bookstores, but I didn't see it in that store today?
