What kind of finch is this?

Can anyone tell me what kind of finch this is? We recently moved from Georgia to Virginia and in spite of taking all of the necessary precautions, our female spice finch didn’t make it. We went to the pet store and got what my husband was told was another female spice finch. She looks nothing like our previous one, and our male spice finch does not seem to like her. (I recognize of course that he may not be ready to move on, but I also know he can’t live alone, because finches are social.) any help?
