Yellow Diamonds

The Sun-Drop Diamond is the largest known Fancy Vivid Yellow pear-shaped diamond at 110.03 carats. It sold in November 2011 for $12.4m.
For centuries the most prized diamonds have been pure white or deep coloured blue, red, pink, or green. Yellow diamonds have not been highly prized, and have been seen as inferior white diamonds.

Yellow diamonds are rare and are much more appreciated today, as celebrities sport the gems regularly. The term “canary” diamonds has been incorporated into the modern term “Fancy Yellow”. The GIA grades natural Fancy Yellow diamonds into 4 main qualities, Fancy Light Yellow (the lightest grade), Fancy Yellow (a medium grade), Fancy Intense Yellow (a strong grade) and Fancy Vivid Yellow (the rarest and strongest).

Yellow diamonds range from a pale delicate yellow to a pure rich canary or sunflower yellow. Yellow diamonds may also have secondary shades, primarily orange or brownish, which affect the clarity of the color. Greenish or pinkish secondary shades are extremely rare and extremely valuable. Yellow diamonds are graded similarly to white diamonds, with the exception of color and cut.

Unlike white diamonds, which are prized on the lack of color, yellow diamonds are graded for clarity of color. Fancy Vivid Yellow grades are extremely rare.
