It’s true that eyes are the windows to a person’s soul. They are also one of the most fascinating parts of a human body that makes a person truly different from the rest. Some scientists even believe that eyes are like fingerprints – there are no two pairs that are totally alike. But when it comes to beauty, there’s hardly a more spectacular mutation than heterochromia iridum. It happens in both animals and human beings, and results in beautiful different-colored irises (that part of the eye that actually has color in it). Here are 15 examples of just how beautiful heterochromia can be.

A combination of hazel and blue is something that is pretty ‘common’ for heterochromia. Nevertheless, it looks absolutely stunning.

Heterochromia doesn’t necessarily happen in both eyes, it can also transform one eye only. But the effect is just as beautiful!

A few centuries ago people with eyes colored like that would have been considered witches or magicians. Either way, today it’s much safer to have heterochromia.

This kitty has partial heterochromia in only one eye. It looks as if someone put a spell on it!

Partial heterochromia can involve only the area around the pupil. The periphery of the eye’s iris has different color than the area close to the pupil. It looks like a star explosion!
