How to choose a Diamond

mcc —  September 13, 2013

Jewellery Latest offer advice on how to spot a good diamond. Cut is the most important factor as discussed here.

The “four Cs” of diamonds which are considered the most important grades and categories:

  • Cut
  • Clarity
  • Colour
  • Carat weight


Because Diamond is a natural substance it can form with flaws, blemishes or inclusions. For the best diamond it should have as few flaws a as possible. The number and size of inclusions or blemishes can effect the grade of the diamond. Most flaws are invisible to the naked eye but can stop light from reflecting perfectly off the cut surfaces of the diamond. Diamonds are graded for clarity under 10x loupe magnification.

  • F
    Flawless: No internal or external flaws. Extremely rare.
  • IF
    Internally Flawless: no internal flaws, but some surface flaws. Very rare.
  • VVS1-VVS2
    Very Very Slightly Included (two grades). Minute inclusions very difficult to detect under 10x magnification by a trained gemologist.
  • VS1-VS2
    Very Slightly Included (two grades). Minute inclusions seen only with difficulty under 10x magnification.
  • SI1-SI2
    Slightly Included (two grades). Minute inclusions more easily detected under 10x magnification.

Richard Burton famously gave Elizabeth taylor an internally flawless diamond in a ring setting called the Krupp Diamond.
