I think you have to have gotten a couple crystal hearts, and maybe defeated the eye of Cthulhu, don't trust that 100% though, i only said think, but that's what happened for me, i got one immediately after i fought the boss and i heard someone say you needed to have a couple crystal hearts, which i did.
