Hello this is my first post. I have been looking at diamonds for some time. I have found this site to be very helpful so I thought I might tap some of the knowledge here to help me get the most rock for the money.
My main question is for a stone to fall into the excellent light return range how do you calculate what is the max diameter that a diamond can be, at a particular weight? I really could care less what the weight of the diamond is but I know that has an effect on price. I just don''t want to give away any apparent size for that weight. I want to get one with the max diameter but still have excellent light return for the size I purchase. The following is kind of what I am looking for:
I am looking for a diamond with excellent light return ( great ideal-scope in the excellent range)
For me symmetry can be at the very good level if the light return is excellent.
I want ideal proportions but I want the largest dia I can get and still have a great cut and Excellent light return.
VS1 or VS2 with clear imperfections.
It needs to be unaltered - no silicon or other treatments to enhance the diamond.
None or very slight florescence
Color at F-I ( really would like GIA cert)
Prefer faceted girdle
Polish excellent maybe very good would do.
Probably a good range to start would be 59-62.5 for the depth and 53-59 for the table but hey you are the expert.
I would like a stone about 7.7mm in dia or slightly larger.
Thanks
