It is pretty rare to find diamonds that meet my selection criteria in the range of 1.40 – 1.49 carats, because the reality is that a diamond cutter has to be stupid to produce anything short of the 1.50 carat mark where the price per carat of diamonds increases dramatically, thus Brian Gavin would have been better off from a financial perspective to cut this diamond to lesser proportions, thus yielding more profit via a higher selling price, but that’s just not his style… Brian Gavin claims to have set the standard for Hearts and Arrows diamonds, and thus this 1.458 carat, Brian Gavin Signature round diamond represents his dedication to cutting diamonds that exhibit the best light performance!
The importance that optical precision in diamonds has upon the volume of light return and the intensity of diamond sparkle is one of the most misunderstood and most important factors of the diamond buying selection process, the optical precision of a diamond is equally as important as the proportions of the diamond.
Optical precision is the term used to describe the degree of precision that the diamond has been cut to, it consists of the consistency of facet shape and alignment, as well as the precision that the facets have been indexed and polished upon the diamond, and it can only be judged by viewing the diamond while unmounted through a hearts and arrows scope, which provides us with the image of the 1.458 carat, I-color, VS-1 clarity, Brian Gavin Signature round diamond above, which exhibits a superior level of optical precision.
Note the precision of the hearts and arrows pattern pictured above, notice how the hearts are all relatively the same size and shape, and that they are spaced evenly, and that the tips of the hearts do not appear to be twisting, this diamond has been cut to a degree of optical precision which is quite impressive!
But what you really want to know, is what benefit does a higher degree of optical precision mean to you in real world viewing conditions — right? Because you’re probably not going to run around town with a loose diamond, looking at it through a hearts and arrows scope all day…
So here’s the deal… Brian Gavin Signature round diamonds are cut to the center “sweet spot” of the range designated for the zero ideal cut proportions rating, as designated by the American Gem Society Laboratory, which sets the standard for the light performance grading of diamonds, leaving the GIA Gem Trade Laboratory in the dust as far as I’m concerned… and this means that Brian Gavin Signature round diamonds are going to exhibit the highest volume of light return, and a virtual balance of brilliance (white sparkle) and dispersion (colored sparkle)… but there are other ideal cut diamonds available with those proportions, so why pay more for a Brian Gavin Signature round diamond — right?
Well for one thing, because Brian Gavin Signature round diamonds also feature lower girdle facets which are 75 – 78% in length, which is going to produce sparkle that is larger in size, and which is bolder, brighter, and more vivid, than it would be if a diamond of the same basic proportions were cut with lower girdle facets in the range of 80 – 82% which will produce sparkle that is smaller in size, and cause the diamond to look more brilliant, as opposed to exhibiting a virtual balance of brilliance and dispersion.
But there are other ideal cut diamonds that are cut to the same proportions, and which also feature lower girdle facets in the range of 75 – 78% and isn’t that going to result in the same volume of light return and light performance?
The short and most accurate answer is “well, sort of…” because without the higher degree of optical precision that is an integral part of every Brian Gavin Signature round diamond, the actual intensity of the sparkle is still going to be lower, and this is because the lack of optical precision, will decrease the uniformity of the virtual facets, and cause the sparkle to be less intense, and this is the performance difference between diamonds which are in the Top 1% of the annual production for round brilliant cut diamonds, and diamonds like this 1.458 carat, I-color, VS-1 clarity, Brian Gavin Signature round diamond, which is easily within the Top 0.001% of the annual production for round brilliant cut diamonds.
Now if you happen to be looking for a diamond in the range of 1.40 – 1.49 carats, and this 1.458 carat, I-color, VS-1 clarity, Brian Gavin Signature round diamond happens to be of interest, do yourself a favor and buy it right now! Because Brian Gavin Diamonds is running a March Madness Sale, and their inventory is flying off the shelves as a result!
If this diamond happens to still be available 24 hours after I publish this blog post, I’ll faint.
