What does an SI1 diamond look like, in terms of clarity?
“What does and SI1 diamond look like?” This is a question we are regularly asked. We have provided the above photograph to prove this. The diamond above is 1 carat in weight and certified by the Gemological Institute of America. You might wonder what the significance might be. Our aim here is to assure those, undecided by SI1 clarity diamonds that diamonds certified by GIA are truly clear of marks to the naked eye. There are diamonds where we recommend higher purities (such as Emerald cut diamonds and Baguette cut diamonds.)
There are many laboratories across the World providing SI1 clarity grades on diamond reports without such exacting standards. Generally GIA is one of the most reputable in their strict diamond grading. For this reason, SI1 clarity graded by GIA is a safe choice. Inclusions within the diamond will be slight, as you would expect at this level on the diamond clarity scale.
The diamond clarity scale, at the lowest purity begins with I3 which is extremely included. The inclusions hinder transmission of light within the diamond and light back to the eye. For this reason, a higher purity is often desired. The diamond clarity, whiteness of the diamond (colour) along with carat weight and cut, produce the value of a diamond. Clarity remains one of the characteristics of diamond grading that eludes and confuses people.
Fact : Many people buy diamonds that are higher in clarity than necessary for fear of receiving a diamond visibly included. Clarity grades such as VVS1, VVS2 and VS1 are impossible to distinguish with the naked eye. For this reason, we would always recommend discussing the diamond in advance. Ensure that your diamond is physically checked. We would never recommend purchasing a diamond purely from a list of details or report copy, unless backed by human checks. For most diamonds, GIA certified stones at SI1 clarity with the backing of GIA certification are a wise idea without any hidden surprises. Hopefully the above provides an answer to the question “What does an SI1 diamond look like?”
