What Does K Mean in Diamonds?

Published in Diamond Grading 2 mins read

In the diamond world, "K" signifies color. It's one of the "4Cs" that determine a diamond's value: carat, cut, clarity, and color.

Diamonds come in various shades, ranging from completely colorless to yellow or brown. The Gemological Institute of America (GIA), a leading diamond grading laboratory, uses a letter grading system to classify diamond color.

Here's how "K" fits into the color grading scale:

  • D - F: Colorless
  • G - J: Near colorless
  • K - L: Faint yellow
  • M - Z: Very light to light yellow

A "K" color diamond is considered faint yellow. This means it has a subtle yellow hue, often only noticeable when compared to a colorless diamond.

Here's what you should know about "K" color diamonds:

  • Price: "K" color diamonds are typically more affordable than colorless diamonds (D-F).
  • Appearance: The faint yellow hue may be barely noticeable to the naked eye, especially in smaller stones.
  • Setting: A setting that complements the yellow hue, like a yellow gold band, can enhance the diamond's beauty.

In conclusion, "K" in diamonds refers to a faint yellow color, which can be an attractive and affordable option for those seeking a diamond with a touch of warmth.
