Something Borrowed, Something Blue: Brian Gavin 1.604 carat, G, VS-2

We all know that wedding etiquette requires that she wear something borrowed and something blue, so this 1.602 carat, G-color, VS-2 from the Brian Gavin Blue Collection of blue fluorescent diamonds.  This diamond just cleared the American Gem Society Laboratory (AGSL) on March 27th and was just posted to the online inventory.  It looks delicious and would solve the requirement for the something blue of the something borrowed, something blue part of the equation in a way which is creative and fun!

The Beauty of a Blue Fluorescent Diamond:

I know from experience that Brian Gavin personally selects every diamond for his Brian Gavin Blue and Brian Gavin Signature Hearts and Arrows Diamond collections, not all of the diamonds which they produce make it on to their online inventory. The diamonds which do make it on to the Brian Gavin inventory tend to be simply stunning and I’m positive that this 1.602 carat, G-color, VS-2 clarity diamond is no exception because I’ve looked over the lab report and the images of the diamond as seen through an ASET Scope and an Ideal Scope and the images look phenomenal.

I have always loved diamonds which exhibit blue fluorescence because they have a radiance about them which is almost magical, especially when the diamonds are exposed to direct sunlight… they kind of pick up a slight lavender blue hue which is quite beautiful.  Hence my reference to something borrowed, something blue… after all, the diamond has really belonged to Mother Nature for the past billion years or so and she is merely loaning it to you to wear for awhile.

Now if you really want to see something stunning, take a look at this puppy in a pitch black room which contains a black light, because it will pop up with the beautiful neon blue color that is captured in the photograph of the diamond which appears at the top of this page.  That is an actual picture of this diamond as seen under black light, it is simply incredible.

The Technical Details:

As you would expect, I looked over the measurements of the diamond and they are right in the middle of the range specified by the AGSL for the zero ideal cut proportions rating and the diamond received an overall cut grade of AGS Ideal which is the highest rating available from the AGS Laboratory for Light Performance, Polish, Symmetry and Proportions.  I could bore you with all the details about how the 34.9 degree crown angle is a great offset for the 40.9 degree pavilion angle but the fact is that it is kind of an unnecessary conversation since the AGSL ran the diamond through their proprietary Angular Spectrum Evaluation Tool (ASET) and gave the diamond a top grade of AGS Ideal 0.  Fewer than 1/10th of 1% of all the round brilliant cut diamonds produced in the average year are cut to the level of cut precision required to produce the light return necessary to warrant that cut grade.  Needless to say this is a spectacular diamond!

The primary inclusions are indicated as being crystals and clouds which quite simply are just tiny diamond crystals which were trapped within the larger diamond crystal as it formed.  As such they’re just diamonds within the diamond and are no big deal, actually they are my favorite type of inclusions because they present no durability concern whatsoever.

The Brian Gavin logo and the number from the corresponding AGSL Diamond Quality Document are inscribed along the girdle edge of this diamond to make it easy for you to identify the diamond.

So there you have it, we’ve solved the something borrowed, something blue part of the what to wear for the wedding dilemma, now all you have to do is put this diamond on hold with Brian Gavin while you select an engagement ring from Brian Gavin.
