That looks a lot like a ringer female I saw at Golli's...
I picked up one of my ringer females as a pet store baby. One of the local pet stores gets a few babies every few months from a private breeder. She happened to be one of them. There are two pictures of her in my gallery, 'Zela' and 'Ringer2'. She's nothing amazing but she's different enough that I didn't mind adding her. I want to point out that I don't consider her a true ringer because she has very little actual white in her 'ring'
