Obviously there are MANY chinchilla mutations, so I will list some of the most common IMO and then an other option where you can fill in your fave if I didn't list it.
I chose black velvet because I think they are beautiful. Granted I love all chinnies. It does not matter to me what color they are. Pink noses will always melt my heart though.
I chose black velvet. I just love the plushness of their fur and their crisp white bellies. My next favourite would have to be the xtra dark ebs. I love me some dark chins.
I have to say that I like mosaics but standards are a close second. However I will say that the personality of the chinchilla is more important and that's why we came home with an ebony. So now that's my third favorite.
I love the mosic because she is my first chin but i really like the extreme marked chins. Id love to have one but they are hard to find and the ones i did find where very $$
I am a sucker for a beautiful, dark standard. I also love, love, love black velvets. I ended up voting for standard because I had to choose just one, but I love both pretty equally. In a close third comes violets.
