Diamond Clarity Grading

Clarity refers to the internal and external flaws and blemishes a diamond has. All diamonds have some sort of flaw, unless graded “Flawless” – which are extremely rare and thus expensive. The scale goes like this:

  • Flawless (FL),
  • Internally Flawless (IF, only surface or polish flaws),
  • Very Very Slightly Included to the First Degree (VVS1),
  • Very Very Slightly Included to the Second Degree (VVS2),
  • Very Slightly Included to the First Degree (VS1),
  • Very Slightly Included to the Second Degree (VS2),
  • Slightly Included to the First Degree (SI1),
  • Slightly Included to the Second Degree (SI2),
  • Included to the First Degree (I1),
  • Included to the Second Degree (I2)
  • and Included to the Third Degree (I3).

We recommend SI1 as a starting point, as we can source 100% eye-clean diamonds (no inclusions or flaws visible to the naked eye). We offer 100% money back guarantee that our GIA certified SI1 diamonds will be eye-clean. Only a trained gemmologist with a loupe will be able to spot the difference. Image description
