The Ultimate Guide To 4cs Of Diamonds

The ultimate guide to 4cs of Diamonds

When buying a loose diamond, it is only necessary to know the basics, and 4C’s are as basic it gets. So, what are the important 4Cs to check before buying loose diamond?

They are Colour, Clarity, Cut, and Carat.

Color of loose diamonds:

Coloured loose diamonds not only form naturally but can also be created in Laboratories. When billions of carbon atoms bond and all are carbon, then a colorless loose diamond is formed.

The GIA lists 27 different hues for natural coloured diamonds, and it is industry’s widely accepted grading system.

The colour grading ranges from D (colorless) to Z (light yellow). GIA's D-to-Z color-grading system measures the degree of colorlessness by comparing a loose diamond under controlled lighting and precise viewing conditions to establish the color value.

More color in a diamond can reduce the prismatic effect of as light passes through the stone. Many of these color distinctions are so subtle that they are invisible to the untrained eye; however, these distinctions make a very big difference on loose diamonds’ quality and price.

  • The slightest quirk creates a colored diamond.
  • A bit of boron makes a blue diamond.
  • Nitrogen makes a yellow diamond.
  • Natural radiation from nearby rocks trap electrons to create a green surface color.
  • Pink or red shades are thought to be due to changes to the electron structure during the voyage to the surface.
  • A chemically pure and structurally perfect diamond has no hue.

Round diamonds are the most expensive and shine the brightest. The GIA Cut Grading System for the standard round brilliant diamond evaluates seven components. The first three are brightness, fire and scintillation; consider loose diamond's overall face-up appearance. The remaining four, weight ratio, durability, polish and symmetry, assess loose diamond's design and craftsmanship.

  • Brightness: Internal and external white light reflected from a loose diamond.
  • Fire: The scattering of white light into all the colors of the rainbow.
  • Scintillation: The sparkle a diamond produces, and the pattern of light and dark areas caused by reflections within the diamond.

You can assess the cut from the grading report from gemological labs. These labs issue one of five cut grades:

  • Excellent – These loose diamonds are very bright. They show even patterns with great contrast between light and dark areas.
  • Very Good – These loose diamonds have bright areas that are evenly distributed with very few distracting areas.
  • Good – These aren’t quite as bright. Reflections aren’t sharp, and there are bit of darkness within the loose diamond.
  • Fair – These loose diamonds will appear dull in some areas, but may have some reflection.
  • Poor – These loose diamonds have very prominent areas of dullness. They don’t have much sparkle

For a round loose diamonds, Cut grade of Very Good or Excellent will have superior brilliance, whereas Fancy shaped diamonds Cut grade of Good or Better will have good brilliance. Avoid loose diamonds with grades below good.
