Interesting Diamonds facts

Color is a very important factor in diamond grading, or more correctly absence of color. Most Diamonds are graded on a Whiteness scale or absence of color scale. The colors that may decrease the value or rarity of a diamond range from yellow to brown to silver to grey. Basically the whiter or clearer the color of the diamond the more rare and stronger the feeling of pureness and beauty.

Please Note: Diamonds come in all colors of the rainbow (see our section on colored diamonds head menu for more information).

Below are the foremost color grading scales ranged together. They are GIA Gemological Institute of America, AGS American Gem Society, CIBJO, the acronym for the French phrase, Confederation International de la Bijouterie, Joaillerie, Orfevrierie des Diamantes, Perles et Pierres, which translates to International Confederation of Jewellery, Silverware, Diamonds and Stones.
