The 4Cs - The COLOUR of Your Diamond

The 4Cs - The COLOUR of Your Diamond - Monroe Yorke Diamonds

In past posts we have talked about the 4Cs of diamond grading and where the grading is described in a Grading Certificate.  If you purchase your diamond from Monroe Yorke Diamonds, this grading process is usually carried out by GIA.  

One of the four main characteristics of a diamond is colour - an important consideration when purchasing your diamond. At Monroe Yorke Diamonds we try to make the distinctions easier to understand before you purchase, and explain why certain colours of diamonds will command higher prices. Loose diamonds must be graded before they are mounted or put in a setting.  This is because surrounding colours can permeate the true colour of the stone.  For example a yellow gold setting will make a diamond look less yellow.  A white gold or platinum setting will emphasise colour.

  • G-H-I-J: Nearly colourless (Carried by Monroe Yorke Diamonds)
  • K-L-M: Faintly tinted, usually yellow
  • N-O-P-Q-R:  Lightly tinted, usually yellow.  Tint can be seen with the naked eye
  • S-T-U-V-W-X-Y-Z: Tinted, usually yellow, may progress to brownish.  Tint visible to the naked eye.

These grades apply to diamonds that are colourless, or those that are yellow through yellowish brown.  They do not apply to fancy coloured diamonds.  Fancy coloured diamonds  have separate colour grading standards.

When referring to colour, a grading report will grade a diamond's lack of colour or whiteness.

D is the highest colour grade with Z being the lowest.
