What is a canary diamond?

Definition
A canary diamond is an intensely yellow fancy colour diamond, named for the bright yellow of a canary bird. In the diamond grading system, colour grades run from D (colourless) down to Z (light yellow), and canary diamonds sit beyond that scale in the fancy colour range, where the yellow is vivid and saturated enough to be an asset rather than a flaw. Natural canary diamonds are rare and valuable; lab-grown canary diamonds offer the same vivid colour at a lower price point.
Frequently asked questions
- How is a canary diamond different from a regular yellow diamond?
- Ordinary yellow diamonds sit in the D to Z colour grading range, where yellow is considered a deficit. A canary diamond is a fancy colour diamond, meaning the yellow is deep and vivid enough that it is graded as a desirable colour rather than a near-colourless stone with a yellow tint. The GIA grades these as Fancy Intense or Fancy Vivid Yellow.
- Are canary diamonds natural or lab-grown?
- Both exist. Natural canary diamonds form underground when nitrogen atoms replace carbon in the crystal structure, which takes millions of years and makes them rare. Lab-grown canary diamonds are created in controlled conditions and have the same chemical structure, but they are much more affordable.
- How much does a canary diamond cost?
- Natural canary diamonds are priced significantly higher than white diamonds of the same carat weight, and the price rises steeply with colour intensity. A Fancy Vivid Yellow natural stone can cost many times more than a Fancy Yellow of the same size. Lab-grown options are far more accessible if the colour matters more than the origin.
