Coco's diamond nose

Happen to read some of the bunny blog recently, some of them some how relate their bunny with diamond. So, i was thinking to write something about diamond and of course, it has to be related to my buns......if u notice closely on the following pictures, my Coco's nose look like a diamond ( the shape), however, this diamond nose appear to be a little bit darker and not shinning........but, have u ever seen any diamond that is able to sniff and wiggle?
