Welcome to the forum. I do not see a photo with your post. If your wife wants a bengal with rosettes, then you should probably make sure the kitten has rosettes. There are so many breeders out there -- good ones -- that I know you can find the perfect kitten for your family.
Note, prices for bengals vary considerably. There was breeders selling for $650 or as much as $2,800 to $3,000. A lot depends on the pedigrees of the parents. If they have a Supreme Grand Champion sire and a Quadruple Grand Champion queen, I am going to charge more money for the kittens due to the quality of the cat. That being said -- a bengal is a bengal and a bengal is a cat, so some of this may not matter to many people.
