Natural Yellow Color Diamond
Natural yellow color diamonds are more common than the other color diamonds. They are still rare considering that for every 10,000 white diamond there is one color diamond. This count includes all the hues. There are dozens of different shades of yellow diamonds, depending on the lightness and intensity of the yellow hue. The purer and richer the color the more prized the gem, although lighter tones can be softly dramatic. Nitrogen is the element that creates the yellow hue in diamonds.
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 largest yellow diamond us a deep brownish yellow called the Incomparable. It weighs 407.48cts and is the third largest diamond. It is graded as internally flawless, the largest example of a diamond with that clarity grading. A young girl playing in the rubble in the town of Mbuji Mayi discovered it in the Democratic Republic of the Congo.
