Diamonds are cut so that the facets act like mirrors ... there are certain angles that these mirrors need to be in order to reflect light in an optimal way. The HCA gives an indication of how well the angles of your diamond can be expected to work together. With GIA, there is rounding of numbers, so the HCA can not always be accurate ... it is a rejection tool only ... it can not be used to choose a diamond but is quite effective in weeding out definite poor performers. If you have a diamond that scores 5, it should be rejected as you can find much better.
Here is a super-ideal A Cut Above 1.071 ct G eye-clean VS2 around the same price .... it is gorgeous with a very small table that is highly sought after by those who love diamond fire ... you would be with a top-notch vendor and a $1 upgrade policy ... imo, this would be a much better option. This is AGS graded, meaning it has been evaluated for light performance, no rounded numbers, no guess work or HCA required, and has the top score.
I agree with the others, I think there are better stones to be found.
@diamondseeker2006 Do not want to thread jack but since coming back around a few months ago, I have been meaning to say hello, glad to see a familiar face after all these years and I always appreciated your sound advice and friendly comments
