The purer and richer the color the more prized the gem, although lighter tones can be softly dramatic.
Yellow diamonds are found in different countries, but South Africa is the source for the notably large and intense yellow diamonds. Many of these larger crystals require a name after they are cut. The Red Cross is the largest known pure yellow diamond; it has an inclusion that looks like the Maltese Cross visible in its top facet. Another South African famous yellow diamond is the Allnatt, a 100-carat fancy vivid yellow.

The color is determined by looking at top of the diamond. There are many variations of yellow diamonds depending on intensity of the color, if it is only yellow in hue or whether there is secondary color detected in the diamond giving it modifying colors such as brown or orange or green. For example if there is a secondary color detected the color would be described as greenish yellow for a yellow diamond with hints of green in its yellow color. These factors determining the hue, tone and saturation are described of a lab report called diamond origin report.
