Blue is the color of the sky on a clear blue day, it is the color of the softest light first thing in the morning, and it just happens to be the best color of fluorescence exhibited by three very special Brian Gavin Signature Blue Fluorescent diamonds which I am going to review today… Because I happened to trip across them while conducting a Search for Brian Gavin Signature round diamonds on behalf of a client who is looking for something just a little smaller in carat weight. I’m not quite sure why, but I found myself singing the lyrics to Blue Velvet, written by Bernie Wayne and Lee Morris in the 1950’s as I looked over the details for these three spectacular blue fluorescent diamonds by Brian Gavin.
And I’ll give you a hint about how special and rare these puppies are… By telling you that I’m writing this review LIVE, clicking on update, paragraph by paragraph, as I spell out the details about why I think these three Brian Gavin Signature blue fluorescent diamonds are so great, because I don’t think they’re going to last long!
Rest assured that I’ve already checked out the details for these three Brian Gavin Signature round diamonds with blue fluorescence, and each one meets my selection criteria, I’d be happy to personally own any one of them! So these Brian Gavin Signature Blue Fluorescent Diamond Reviews are all positive, 100% fantastic, with nothing negative to say about any one of these three diamonds, so click on the order button if any one of them appeals to you, because all three are brand spanking new diamond inventory, which I expect them to sell very quickly!
This 1.365 carat, H-color, VS-1 clarity, Brian Gavin Signature diamond with strong blue fluorescence is guaranteed to be a knock-out, because the pavilion angle of 40.8 degrees will provide a high volume of light return, while the 34.8 degree crown angle provides a virtual balance of brilliance (white sparkle) and dispersion (colored sparkle) and the 76% lower girdle facet length is going to produce broad spectrum sparkle, which is larger in size, bolder, brighter, and more vivid, than what you can expect from the average ideal cut diamond, which features lower girdle facets in the range of 80 – 82% and this is critical because diamonds with longer lower girdle facets, tend to produce smaller, pin-fire type sparkle, which our human eyes have difficulty dispersing into colored light, so those other ideal cut diamonds are likely to exhibit more brilliance, but less fire. Where’s the balance?[separator]
The strong blue fluorescence which landed this puppy in the Brian Gavin Blue Signature diamond collection is similar to the blue fluorescence exhibited by these jelly fish that were photographed at the Monterrey Bay Aquarium in California. This photo is courtesy of Brian Gavin’s blog post pertaining to the effect of strong blue fluorescence on a J-color diamond. The strong blue fluorescence is likely to boost the H-color of this diamond towards G-color, when the diamond is viewed in lighting conditions that contain lots of ultra-violet light.[separator]
This 1.365 carat, H-color, VS-1 clarity, Brian Gavin Signature diamond with will look perfectly normal when viewed in normal lighting conditions, but will glow a spectacular neon blue color, which is very similar to the neon blue color exhibited by these jelly fish, when the diamond is exposed to black light. How cool is that?
Blue fluorescence in diamonds is kind of like a secret super power, which can help diamonds look brighter and whiter; but blue fluorescence in diamonds can have negative effects as well, such as causing diamonds to look milky, or cloudy, however this is quite rare; according to a study conducted by the Gemological Institute of America (GIA), fewer than 2% of gem quality diamonds are negatively impacted by the influence of fluorescence, this primarily occurs in diamonds that exhibit very strong to distinct blue fluorescence.
One of the distinct advantages of buying a blue fluorescent diamond from the Brian Gavin Blue Signature collection, is that Brian Gavin personally evaluates every diamond that is produced under his direction, to ensure that the fluorescence is a positive influence upon the appearance of the diamond. I’ve been buying diamonds from Brian Gavin for close to 25 years now, and he’s never failed me!
If you’re looking for a diamond in the range of 1.50 carats, but don’t want to get creamed by the price increase that occurs between the 1.49 – 1.50 carat marks, then this 1.404 carat, G-color, VS-2 clarity, Brian Gavin Signature diamond is definitely worthy of consideration! As with all Brian Gavin Signature diamonds, this diamond has been graded by the American Gem Society Laboratory (AGSL) with an overall cut grade of AGS Ideal-0 on their proprietary Light Performance grading platform, which relies on Angular Spectrum Evaluation Technology (ASET) to determine how effectively the diamond is making use of the light which is available to it from within the room! This diamond exhibits lots of red, which means that it is going to be incredibly bright, and the even distribution of colors, means that light is reflecting evenly throughout the diamond! More on what the different colors of ASET mean.[separator]
As with the other Brian Gavin Blue Signature diamond reviewed above, this 1.404 carat, G-color, VS-2 clarity, Brian Gavin Signature round diamond exhibits blue fluorescence, but the degree of fluorescence is medium blue instead of strong blue, which is a degree of fluorescence which is an absolute no-brainer, because it there is no chance that it can negatively impact the visual properties of the diamond in any way… it can only have a positive effect upon the visual properties of the diamond.
You probably know by now that Brian Gavin cuts all of his signature diamonds to exhibit the highest volume of light return, and exhibit a virtual balance of brilliance (white sparkle) and dispersion (colored sparkle) and that the sparkle will be broad spectrum, which will be larger in size, and bolder, brighter, and more vivid, than the sparkle displayed by most ideal cut diamonds; and this is because Brian Gavin designs each diamond with just the right proportions, and a degree of optical precision that is optimized to deliver maximum visual performance.
And this is certainly true of this 1.404 carat, G-color, VS-2 clarity, Brian Gavin Signature round diamond which has a pavilion angle of 40.8 degrees, which is offset by a crown angle of 34.8 degrees, with 77% lower girdle facets! By all indications, this puppy should be a Rock Star! I can’t wait to see the reflector scope images, it certainly looks fantastic in the ASET scope image provided on the diamond grading report issued by the AGS Laboratory… I wouldn’t wait for Brian Gavin to update the diamond details page with the clarity photograph, scope images, and high resolution video of this diamond, I would order it now and get it reserved in your name, pending final approval of the diamond upon publication of the photographs, because diamonds like this are so rare that they don’t last long once the listing goes public!
Without a doubt, this 1.480 carat, F-color, VS-1 clarity, Brian Gavin Blue Signature diamond with strong blue fluorescence is The Cat’s Meow! And since the carat weight of 1.480 carats is within two points of the 1.50 carat mark, it could legally be sold as a 1.50 carat diamond, because the legal definition of “a carat and a half diamond” is that it must weigh between 1.48 – 1.52 carats, so you can totally call this “a one and a half carat diamond” and get away with it! But the price is so much better than it would be if the diamond actually weighed 1.50 carats, because it falls just short of the diamond price per carat (PPC) increase that occurs between the 1.49 – 1.50 carat marks! And the strong blue fluorescence provides an additional discount, making this diamond the kind of super duper great buy, with the kind of light performance and sparkle factor that I personally look for in a diamond![separator]
Not only does this 1.480 carat, F-color, VS-1 clarity, Brian Gavin Blue Signature diamond with strong blue fluorescence have an overall cut grade of AGS Ideal-0, but it looks spectacular in the ASET scope image, indicating that it is nice and bright, and full of light! Not only is it cut to ideal proportions, but it also exhibits a degree of optical symmetry that is going to produce sparkle that is bolder and brighter! The 40.8 degree pavilion angle will definitely provide a high volume of light return, while the 34.4 degree crown angle provides a virtual balance of brilliance and dispersion, and the 77% lower girdle facet length is going to produce that broad spectrum sparkle that I’ve been talking about!
And you might be beginning to notice a pattern of excellence that exists within the Brian Gavin Blue Signature line of diamonds, they all have an overall cut grade of AGS Ideal-0, and have proportions that are optimized to deliver the highest volume of light return, with a virtual balance of brilliance and dispersion, with lower girdle facet lengths that consistently produce broad spectrum sparkle… it’s almost as if Brian Gavin cuts Brian Gavin Signature diamonds to consistent standards on purpose, there just might be something to that fifth generation diamond cutter thing 😉
Obviously I continue to be impressed with Brian Gavin Signature diamonds, the production quality continues to be exceptional, and the light performance that results from it continues to be the very best! I’ve been buying diamonds in bulk from Brian Gavin Diamonds for close to 25 years now, and have yet not to be impressed with the cut quality and sparkle factor that results from it! You simply can’t go wrong picking a diamond from the Brian Gavin Signature diamond collection, but I’m happy to help you cherry pick the very best of what Brian Gavin to offer if you’d like to take advantage of my free Diamond Concierge Service, it costs you nothing and does not affect your purchase price!
