Selecting Your Diamond

You’ll want to become familiar with the Diamond Guide.  It’s a combination of cut, colour, clarity and weight that contribute to the quality and beauty of the diamond.

  1. Cut: The quality of the cut affects the outward appearance of the diamond, including its light-reflecting properties and brilliance
  2. Colour: Diamonds are graded according to how white or colourless they are. Most white diamonds that appear to be clear and colourless are actually slightly coloured. 

    Recent diamond trends have seen an increase in popularity of coloured diamonds, such as pink, yellow and even brown diamonds. Known as fancy diamonds, these can be just as rare and valuable as colourless or white diamonds.
  3. Clarity: This refers to the extent to which a diamond is free of flaws. Almost all diamonds have flaws; however, in terms of evaluating the quality of a diamond, less is better.
  4. Carat: The weight – not the size – of a diamond is measured in carats.  When shopping for a diamond the carat weight can be a matter of personal taste.
