Diamond Clarity

The Clarity of a diamond is by far the most important of the four C’s that make up the quality of a diamond or any other precious stone. To put it simply, a diamond’s clarity refers to the combination of all the inclusions and blemishes it has.  Inclusions refer to imperfection existing on the inside of a diamond whilst blemishes are used to describe imperfections existing on the outside surface. Within both groups there is a list of specific types of imperfections each with their own specific name, but the most important thing to remember is that each imperfection will make it harder for light to pass through the stone. Because some imperfections will block more light than others, the combination of all the imperfections found in a stone will result in a certain score on the clarity scale. Gemologists use various techniques and state-of-the-art technologies to identify these imperfections in order to place each stone within a specific range of the GIA clarity scale.

  • FL or “Flawless” – No inclusions and no blemishes visible under 10x magnification
  • IF or “Internally Flawless” – No inclusions visible under 10x magnification
  • VVS1 &VVS2 or “Very, Very Slightly Included” – Inclusions so slight they are difficult for a skilled grader to see under 10x magnification
  • VS1 & VS2  or “Very Slightly Included” – Inclusions are observed with effort under 10x magnification, but can be characterized as minor
  • SI1 & SI2 or “Slightly Included” – Inclusions are noticeable under 10x magnification
  • I1, I2 & I3 or “Included”: Inclusions are obvious under 10x magnification which may affect transparency and brilliance

“FL, IF and VVS” are the most rare and also the most expensive clarities that can be found in the market.  “VS and SI” are the most common and commercial diamond clarities whilst “I” is the least popular and usually also referred to as Pique quality. All diamond in our stock are GIA certified so they all have been graded on clarity along the GIA clarity scale
