Know your 4 C’s of Diamond Quality

The universal method for assessing the quality of any diamond, anywhere in the world. They are: Clarity, Colour, Cut, and Carat.

clarity

  • Diamonds have a variety of internal characteristics called ‘inclusions’, as well as external characteristics called ‘blemishes’
  • No diamond is 100% pure, but the more chemically refined the stone, the better clarity it has
  • Diamonds are graded based on their purity, using a scale from I (inclusions that are obvious to the naked eye) to Flawless (no inclusions and no blemishes visible under 10x magnification).

color

  • The color evaluation is based on the absence of color.
  • Chemically pure and structurally perfect diamonds have no hue, and consequently, a higher value.
  • The highest color grade for a diamond is D, which is completely lacking in color. As the grade gets lower (up to Z), the diamond becomes more colored and therefore lower quality.

  • At Kimaï, we focus on stones with color grading above H.

cut

  • We often think of a diamond's cut as shape (round, emerald, pear), but a diamond's cut grade is really about how well a diamond's facets interact with light.
  • Precise artistry and workmanship are required to fashion a stone so its proportions, symmetry, and polish deliver the magnificent return of light only possible in a diamond.

carat

  • Carat weight is the measurement of how much a diamond weighs.
  • A metric 'carat' is defined as 200 milligrams. Each carat can be subdivided into 100 'points'.
  • This allows very precise measurements to the hundredth decimal place.
  • All else being equal, diamond price increases with carat weight.

clarity

  • Diamonds have a variety of internal characteristics called ‘inclusions’, as well as external characteristics called ‘blemishes’
  • No diamond is 100% pure, but the more chemically refined the stone, the better clarity it has
  • Diamonds are graded based on their purity, using a scale from I (inclusions that are obvious to the naked eye) to Flawless (no inclusions and no blemishes visible under 10x magnification).
