Generally, people that buy yellow diamonds would like their diamond to look as yellow as possible. The goal is most often to make Fancy Light Yellow or Fancy Yellow Diamonds look like they are Fancy Intense Yellow or Fancy Vivid Yellow. This can be accomplished by skillful mounting. By surrounding the sides and bottom of a yellow diamond with high karat yellow gold, the face up yellow color will apear more yellow. The sides and shanks of the mounting are often 18 karat white gold or platinum and usually set with the whitest (colorless) side diamonds. These white side diamonds, in white metal, provide the striking contrast to make the Canary Diamond look as vivid as possible. You can look at some good examples on our portfolio page.

- Man can mount diamonds to make them look more yellow.
- Man can make synthetic yellow diamonds. These lab grown or lab created diamonds have never been in the ground.
- Man can treat natural (from the ground) diamonds to give them their canary yellow color. Man can make them yellow by irradiating them, by treating them under high pressure high temperature (HPHT) or man can coat them.
Canary Diamonds are those classified as Fancy Light Yellow, Fancy Yellow, Fancy Intense Yellow and Fancy Vivid Yellow. Obviously the value of Canary Diamonds are also affected by the other 3 C's besides color. Clearly clarity, cut and carat weight are important factors. The lower the clarity the poorer the cut, and the smaller the diamond, the lower the value. There are many more subtle factors that could impact a Canary Diamond's value.For example blue fluorescence can make a yellow diamond look less yellow when viewed under a long wave ultra violet light which is found in normal daylight. Therefore blue fluorescence is a negative. Tones are another factor as darker tones are generally less valuable than their lighter toned counterparts.
