Review of Brian Gavin Signature Hearts and Arrows Diamond 2.718 carats, G color, VS-2 clarity

This review is for a diamond which I’ve been following for awhile as it moved through the planning and production process and on to the AGS Laboratory for grading… it’s one of those diamonds which is of extreme interest to those of us in the diamond industry who share a passion for diamonds carefully crafted for maximum visual performance and sparkle factor. It is a diamond which Brian Gavin and I have been discussing for quite some time and I feel kind of honored to have a chance to review it.

Awhile back Brian Gavin and I were chatting via Skype as we often do and he excitedly told me about this diamond which was in the process of being planned for production… we’d been talking about the scarcity of well cut diamonds in the range of 2.00 – 2.99 carats, especially between 2.50 – 2.99 carats and all of the sudden he got this wicked twinkle in his eye and a great big smile spread across his face and he said “Oh I have something in the works that you’re going to love!”

With great passion and excitement Brian proceeded to tell me all about this diamond which was in production which was going to finish out in the range of 2.65 – 2.75 carats and probably be G-color and VS in clarity and that it was going to be cut like a dream… I got a sneak peek at the lab report in the latter part of January while the diamond was clearing the grading process at the AGS Laboratory and  I have to admit that I myself could not wait for the diamond to be returned to Brian Gavin so that it could be photographed and placed on the web site for sale… I also got a sneak preview of the diamond when Brian held it up for me to see during one of our Skype calls and it was stunning!  The finished diamond ended up being a Brian Gavin Signature Hearts and Arrows Cut Diamond weighing 2.718 carats, VS-2 clarity, G color with negligible fluorescence.

Getting Swept Away By The Current…

I knew that the diamond would not be available for long, but I have to admit that I was slightly surprised when Mark C. popped up inquiring about the diamond as soon as it became available on the web site… it was right in the middle of Super Bowl Sunday and he wanted to know my opinion of the diamond because he had already placed it on hold and was ready to pull the trigger.

All I could truthfully tell Mark about the diamond is that Brian and I had been discussing it for awhile and that Brian was truly excited about it… but that there wasn’t a whole lot that I could tell from the details provided on the AGS Platinum Light Performance diamond grading report other than the proportions of the diamond looked spot-on and the image created by the ASET Scan looked wonderful.  However I was going to need to see the images of the diamond as seen through an ASET Scope, an Ideal Scope, a Hearts and Arrows viewer and that I wanted to see the computerized proportions analysis of the diamond to determine the spread between the measurements which the average crown and pavilion angles indicated on the proportions diagram of the AGS diamond grading report are based upon.

The Nitty Gritty Details…

It took a few days longer than I expected to get all of the details, but this diamond was part of a rather large parcel of diamonds which Brian Gavin Diamonds had sent into the AGS Laboratory for grading and they’ve been scurrying like mad trying to get all of the diamonds photographed and processed for the web site because quite a few people have been begging to get the diamond which they are interested in pushed to the front of the pile… well today I received the images for the diamond and I am impressed.

I’d already seen the diamond grading report from the AGS Laboratory, so I went straight to the computerized proportions analysis of the diamond and the spread between the high and low measurements which the average crown and pavilion angle measurements indicated on the lab report are based upon is nice and tight… this is critical to creating a diamond with a high degree of sparkle factor and from what I saw of the diamond via Skype it’s drop dead gorgeous!  Brian was having a bit of trouble getting the web cam to focus on the diamond, but it was dancing beautifully in the light and exhibited a beautiful and sparkling personality!

Truly a Hearts Delight…

Next I took a close look at the image of the diamond as seen through a Hearts and Arrows viewer and was pleased to see that the diamond exhibits a crisp and complete pattern of Hearts that is consistent in size and shape.  The reason I’m so fond of Hearts and Arrows Diamonds is because what enables us to see anything is contrast and the precision of diamond cut quality which produces this beautiful pattern creates a lot of contrast which makes the beauty of the diamond POP and creates an amazing amount of sparkle.


When judging Hearts and Arrows Diamonds for diamond cut quality, I look for a reasonable amount of consistency in the size and shape of the hearts; to see that the tips of the hearts are not bent and twisting; to see that there is consistency in the amount of spacing between the tips of the hearts and the arrowheads which appear beneath them and that the clefts of the hearts and consistent in shape.  All of these things fall into place with this diamond, I am quite pleased.

It Just Gets Better and Better…

The ASET and Ideal Scope images for this diamond are equally precise and consistent.  In case you are not familiar with the concept behind the ASET Scope, it was designed by the AGS Laboratory to determine where in the room a diamond was gathering light from and how it is returning that light towards the viewer (that’s you).

This diamond is performing wonderfully and the image is essentially a textbook representation of how things should be… the diamond is exhibiting a lot of red and just a little bit of green which means that the diamond is going to be nice and bright!

The contrast created by the arrows pattern is consistent and dark which is excellent, this diamond is going to be a barnstormer of brilliance and dispersion.  The pattern of red, white and black present in the Ideal Scope image is consistent and even… the diamond is reflecting the majority of light which is entering it back up towards the viewer and exhibits very little leakage, essentially it is a text book version of how a super ideal cut diamond should look when viewed through these scopes.

And Finally a Little Bit of Clarity…

The last thing I looked at were the inclusions within the diamond because I’d already had a chance to preview these on the AGS diamond grading report and I already knew that the inclusions were perfectly acceptable… all you have within the diamond are tiny diamond crystals, long thin needle shaped diamond crystals and small clusters of pinpoint size diamond crystals which are referred to within the industry as clouds.  So essentially the inclusions within this diamond are tiny diamonds that were trapped within the larger diamond as it formed, diamonds within the diamond if you will.

This 2.718 carat, G color, VS-2 clarity, Brian Gavin Signature Hearts and Arrows Cut Diamond is flat out, hands down a winner… I’m kind of bummed that it’s not going on my hand, but it’s exactly the type of diamond that I would be looking at for myself if I were in the market for a wonderfully large piece of Nice Ice!  I’m totally jealous!  Seriously.
