Diamond Clarity

Diamond clarity

Diamond clarity is a very interesting and fluid topic. Because diamonds are formed deep within the earth’s crust under extremes of heat and pressure, they usually contain unique birthmarks called inclusions, which are imperfections within the diamond itself.

No single diamond is absolutely perfect under 10x magnification, apart from those few that have been graded Flawless by the Gemological Institute of America (GIA) and those are so rare that most jewellers have never even seen one, let alone sold one!

Each and every diamond is unique and as diamond graders, it’s important to us at Australian Diamond Brokers that we only purchase diamonds that we are proud to stock and sell. That means even if a diamond has imperfections in it, they must still be invisible to the naked eye and not hinder in any way the beauty and sparkle of the diamond itself. We are experts are understanding diamond clarity.

The GIA Clarity Scale

In determining a clarity grade, the GIA system considers the size, nature, position, colour, and quantity of clarity characteristics visible under 10x magnification. The GIA Clarity Scale contains 11 grades, with most diamonds falling into the VS (very slightly included) or SI (slightly included) categories.

Grades include;

  • Flawless (FL) – no inclusions or blemishes visible to a skilled grader using 10x magnification
  • Internally Flawless (IF) – no inclusions and only blemishes visible to a skilled grader using 10x magnification
  • Very, Very Slightly Included (VVS1 and VVS2) – inclusions difficult for a skilled grader to see under 10x magnification
  • Very Slightly Included (VS1 and VS2) – minor inclusions that range from difficult to somewhat easy for a skilled grader to see under 10x magnification
  • Slightly Included (SI1 and SI2) – noticeable inclusions to a skilled grader under 10x magnification
  • Included (I1, I2, and I3) – obvious inclusions under 10x magnification that may affect transparency and brilliance.
