Are all Brian Gavin Signature diamonds super ideal?
“I’m very interested in this 1.111 carat, VS-2 clarity, G color, Brian Gavin Signature diamond with medium blue fluorescence; however a friend of mine suggested that I only consider diamonds which are super ideal cut. I’m a bit confused because several references that I’ve found online seem to suggest that Brian Gavin Signature diamonds are super ideal cut, however the diamond grading report for this diamond only indicates an overall cut grade of AGS Ideal-0 and it seems like the Light Performance grading report is the most complete diamond grading report issued by the American Gem Society Laboratory. Are all Brian Gavin Signature diamonds “super ideal” or is there another classification of diamonds that I should be asking for? Are there any other diamonds that you would recommend in this range of clarity and color? My price range is $10k ± ”
The definition of a Super Ideal Cut Diamond:
There are different classifications of ideal cut diamond, which are based upon the proportions of the diamond, as well as the degree of optical symmetry exhibited by the diamond when it is evaluated using various reflector scopes that are designed to help professional diamond graders judge optical symmetry; specifically these devices are the ASET Scope, Ideal Scope, and Hearts & Arrows viewer. The photograph provided to the left, shows how the 1.111 carat, VS-2 clarity, G color, Brian Gavin Signature diamond looks when viewed through an Ideal Scope, which is primarily used to detect light leakage that might result from less desirable proportions or poor optical symmetry.
The range of proportions designated by the American Gem Society Laboratory (AGSL) for the zero ideal cut rating, is rather broad by our standards; the range of proportions designated for the Brian Gavin Signature diamond collection represents what is essentially the middle of the spectrum encompassed by the zero ideal cut AGSL proportions scale, and as such, many people would consider this to be “super ideal” because the combination of crown angle and pavilion angle measurements within this range are widely recognized as providing the highest volume of light return and a virtual balance of brilliance and dispersion.
However the proportions of a diamond are only part of the puzzle with regards to the sparkle factor, the optical symmetry, or consistency of facet shape, facet size, and the indexing of the facets, and how the facets align with each other from the perspective of 360 degrees, is also a critical factor; and as such, we feel that a true “super ideal cut diamond” must be cut to proportions that are within the center of the range designated for the zero ideal cut proportions rating, and exhibit the highest degree of optical symmetry, which all Brian Gavin Signature diamonds do.
Are Brian Gavin Blue Fluorescent diamonds super ideal?
The primary difference between the diamonds placed in the Brian Gavin Blue collection of diamonds which exhibit blue fluorescence, and the diamonds placed in the Brian Gavin Signature line, is the presence of blue fluorescence; all of the diamonds are produced by the same diamond cutters, on the same production line, and it is not likely that the diamond cutters know which diamonds are being cut for the Signature line and which are being cut for the Brian Gavin Blue collection, because they aren’t checking for fluorescence on the production line. The medium blue fluorescence in the 1.11 carat diamond, pictured to the left, is only visible when the diamond is exposed to black light.
So whether you buy the 1.111 carat, VS-2 clarity, G color, Brian Gavin Signature diamond with medium blue fluorescence, which you referenced above, or this 1.108 carat, G-color, VS-2 clarity, Brian Gavin Signature round diamond which has negligible fluorescence, you can rest assured that the diamond is going to exhibit the highest volume of light return and sparkle that is absolutely incredible!
