I have never seen anything like that, and if its a he it can not even be a tortie.
In Sweden they describe something they call Mosaik and i was wondering if you hamster maybe was that, i have borrowed a picture from the swedish hamsterclubs homepage of a creme mosaik Satin.
In sweden they describe the color: the color have to follow the standard, and the hamster most have one or more spots.
the hamster may not be golden, it most have a mutatated color.
The spots may not be white or yellow, but of a darker or golden character, thats mean the cells there where the spots are, have mutated back to a natural color, useually golden.
I dont know if they may have black spots but i think so, but your hamster have very big spots so i really dont know what it is this was just a little guess.
But i would like to know the color of the parrents to.
And then i most say its a very special and very pretty hamster you have.
