This diamond’s clarity is very slightly included, with impurities not visible to the eye. VVS and VS are very good which means you would need a microscope to see any flaws.

SI1 SI1 and SI2

Diamond clarity on these diamonds means the inclusions are visible under 10-power magnification and might be visible to the unaided eye.  A diamond is graded SI1 even though it has no more inclusions than a VS2, but because those inclusions occur in the centre of the diamond, they are more noticeable and more likely to block light.

Which is better: IGI or GIA diamond certification?

While GIA and IGI certificates are both reputable and backed by leading laboratories, there is a more widespread use of GIA certificates within the natural diamond industry and among jewellers. However, both IGI and GIA grade on the same basic principles and diamond characteristics. Therefore, both can be trusted to provide honest assessments of diamonds.
