Everything goes to extremes, and white diamonds with extremely poor color have become treasures in the eyes of collectors
Today we are going to talk about yellow diamonds, which are a type of colored diamonds. They are deeply loved by diamond collectors because of their bright colors and rare production. Although the production of yellow diamonds is low, yellow diamonds are produced in diamond mines all over the world.
Yellow diamonds are actually white diamonds whose carbon atoms are replaced by nitrogen atoms and become yellow. The intensity of the color depends on the nitrogen content. This exchange causes diamonds to absorb blue light and selectively transmit yellow light, resulting in a strong yellow hue. We know that one of the 4C standards for white diamonds is called "color," which ranges from D to Z, with D being the whitest. The color becomes yellower as the color grade exceeds Z before it can enter the category of colored diamonds.
Can those above grade Z be called yellow diamonds? In fact, yellow diamonds are also divided into grades.
Level from low to high
Fancy Light Yellow
Fancy Yellow
Fancy Intense Yellow
Fancy Deep Yellow
Fancy Vivid Yellow
Although yellow diamonds are very common, yellow diamonds that reach the level of Fancy Vivid Yellow are extremely rare. According to statistics from the Gemological Society of America, less than 5% of the yellow diamonds they have identified can reach the level of Fancy Vivid Yellow. This shows that yellow diamonds are very rare.

Main distribution
Although yellow diamonds can be found in diamond mines all over the world, only diamonds with a deep yellow hue have higher artistic and commercial value. These deep yellow diamonds are mainly distributed in southern and central Africa, and the Ellendale Mine in Western Australia is the world's largest single producer of rare fancy yellow diamonds.
