What is the size difference between diamonds weighing 1.20 carat to 1.66 carats?

A customer contacted me recently wanting to know the size difference between diamonds weighing between 1.20 – 1.66 carats, she was considering several options from Brian Gavin Diamonds. Since a picture is worth a thousand words, I thought it would be helpful for her to have a visual reference of the five diamonds which she was considering, so I asked Brian Gavin to set them out side-by-side on a sorting tray and snap a quick picture for me.  Now understand, this is not a glamour shot, it isn’t intended to show how beautiful these diamonds are, it was taken on the fly, using a camera phone, under fluorescent lighting, and the diamonds are not to scale… but it does provide a great visual which I thought was worthy of being shared.

All right, the diamonds featured in this photograph, from left to right are as follows:

Brian Gavin Signature Diamond weighing 1.232 carats, H-color, VS-1 clarity

Brian Gavin Signature Diamond weighing 1.237 carats, F-color, VS-2 clarity

Brian Gavin Signature Diamond weighing 1.315 carats, I-color, VS-1 clarity

Brian Gavin Signature Diamond weighing 1.504 carats, I-color, VS-2 clarity

And the 1.668 carat, J-color, VS-1 clarity, Brian Gavin Blue fluorescent diamond which I reviewed a few days ago, you can read all about that beautiful puppy here.

All of these diamonds have been graded by the American Gem Society Laboratory (AGSL) with an overall cut grade of AGS Ideal-0 and exhibit a crisp and complete pattern of Hearts & Arrows.

The inclusions within all of them look fantastic, all of them have inclusions which meet my selection criteria, these are all diamonds which I would consider purchasing myself if I were in the market for a diamond.

Now which one to buy is not such an easy decision, it really comes down to your personal preference for carat weight, or color… and of course cost is a factor.  But as far as the volume of light return and the sparkle factor, they are essentially equal, to the extent that I don’t think you could go wrong choosing any one of them!
