As previously mentioned, the best “color” for a diamond is the absence of color. Traditionally, diamonds in engagement rings are colorless or almost colorless, but it's first of all a matter of taste.

The most prized diamonds are colorless diamonds, because their beauty depends entirely upon their remarkable optical properties. In such diamonds, all the colors of the rainbow are reflected back to the eye.
These stones are relatively rare, the most frequently found diamonds being of industrial quality.
Those suitable for gem use (only about 20% of all diamonds) usually have some yellow tint.
A truly colorless stone is rare indeed and will, by all means, have a premium price. The larger such a diamond, the greater the premium per carat.
For every carat of polished gem quality diamond, about 250 tons of kimberlite must be mined.

World's Largest Colorless Diamond

World's largest colorless diamond ever found is the Cullinan Diamond.

This diamond was found by Thomas Cullinan in 1905 and was 3,106 carats uncut.

It was sold and later given to King Edward VII of England as a birthday gift.

The King commissioned the Asscher brothers to cut jewels from it, the most famous being the Great Star of Africa of 550.20 carats.

Choosing a Colorless Diamond

A diamond's color is graded. D is the best grade (there is no A, B, or C), and Z is the worst grade.

Grades D-F are called “colorless” and grades G-J are called “near colorless”.

Tips

• Grades D-I usually look pretty much “colorless” for a non-expert eye. So, if you don't want to spend a “fortune” on a diamond engagement ring and if she isn't really keen of possessing a D-I graded stone, you can easily opt for a color grade in the G-I range that'll save you some money and still get you a lovely rock.
• Diamonds graded J-M are going to have a bit of a “warmer” glow than D-I. Some people prefer them, but make sure she is one of those people before you buy. If the purchase is a secret and you can't get the recipient's input, stay in the D-I range. It is advisable not to buy a diamond with a color grade below K.
• The bigger the diamond, the more visible color “issues” become. In other words, don't think you can make up for low quality color by getting a bigger stone. You're just going to make the low quality more noticeable.
• As for fluorescence, although a controversial issue, the safest would be to keep within none to very light range.
