Iris

Simply beautiful. According to Wikipedia, the name also means "halo of the Moon" in ancient Greek. Additionally, there's a bright, striking nebula in the constellation Cepheus called the Iris Nebula.

In Middle English, the word "Iris" also referred to a rainbow-like prismatic rock crystal.

Means a part of the eyeball, a delicate flower or a goddess of the rainbow. Kids with this name get teased, according to an Iris I know. Unless you're gorgeous, it's not good. Imagine an overweight gawky kid with this name.

I named my daughter Iris! It wasn’t until after she was born that I found out that Irish is a very popular name (in places like the Philippines) and that she would be mistakenly called that with alarming regularity. Iris is, in addition to other things already mentioned here, also a part on an optical microscope. The Iris diaphragm controls the diameter of the beam of light entering the lens system, affecting contrast and focus in combination with other microscope parts.

Iris has a powerful meaning. The goddess, Iris, rode rainbows from earth to the heavens carrying messages to and from the gods to earth. She was a messenger goddess. Most people who have named their girl Iris that I know have named them because of this. No one who names their child Iris, names them for the anatomical part. That is like saying to all those boys named Matthew, who are called Matt, that they are named after a doormat, instead of "gift of God".

Iris can have two separate meanings. Much like the old English
name Spring. To bring forth and leap or the season Spring.
Iris, the pupil in your eye or Iris the beautiful purple or yellow
Bearded flower like tulip.

In French, Iris is also a blue/purple flower.
