Color
When it comes to color, less is more.
Color: This part’s pretty simple. When you’re shopping for a diamond, you’re usually looking for a diamond with very little overall color. How much is really a matter of individual taste.

The Gemological Institute of America (GIA) has created a universal scale to measure and grade the color, or colorlessness, of a diamond (see below). Diamonds are graded for color under a lamp that simulates daylight, against a pure white background.
The lower on the scale you go the color of the diamond will become more intense. It’s actually possible for a diamond to go below a "Z" color, but at that point the diamond is re-categorized as a "Fancy Color Diamond." These diamonds exhibit intense colors such as blue, pink, yellow green or even red and have their own set of grading parameters. They are extremely rare — most of us will only ever see them in a museum!

For most people, the difference between colorless, near colorless, and even the highest range of faint yellow diamonds can be hard to see. But these tiny differences can have a huge impact on price. So when you’re looking at different diamonds, you might decide to give a little bit on color so you can afford a better cut — or more clarity. That’s up to you — and her!
