To many, eyes are the most beautiful part of the body. Not only are they the windows to the soul, but their color and size can vary considerably from person to person. 

Have you ever heard of heterochromia iridum? This interesting abnormality is characterized by the iris (colored part of the eye) being different colors in each eye. While heterochromia is a rare mutation, it is arguably one of the most beautiful mutations that a human, or an animal, can have.

Here are 16 pictures showing how magnificent heterochromia can be.
