Yellow Diamonds

The pear-shaped Sun-Drop Diamond is the largest known Fancy Vivid Yellow 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 blue, red, pink, or green. Yellow diamonds have not been highly prized, and have been seen as inferior to white diamonds.

Yellow diamonds are rare and are much more appreciated today. Yellow diamonds range from a pale delicate yellow to a pure rich canary or sunflower yellow. The term 'canary' diamonds has been incorporated into the modern term “Fancy Yellow”.

 The GIA grades natural Fancy Yellow diamonds as Fancy Light, Fancy Yellow, Fancy Intense and Fancy Vivid.

The Graff Fancy Vivid Yellow diamond weighs 100.09 carats and is graded VS2 clarity. It set a world auction record for a yellow diamond in 2014 at $16,347,848

Yellow diamonds may have secondary shades, primarily orange or brownish, which affect the clarity of the color. Greenish or pinkish secondary shades are extremely rare and 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 very rare.
