Brian Gavin Signature Hearts & Arrows Diamonds Review


We talked about how Brian Gavin came to be the icon that he is in my overview of Brian Gavin Diamonds. His reputation is set in stone in the industry as his astonishing perfectionism for the faultless diamond cut urged him to pioneer the legendary (H&A) hearts and arrows diamonds!

To give you deeper context, back in 2004, Brian Gavin presented a formal paper at the 1st International Diamond Cut Conference in Moscow and explained how H&A diamonds should be graded.

Major grading labs and industry peers approved and endorsed this new hearts and arrows criteria. He proudly claims that his signature hearts and arrows diamonds are optically balanced for maximum visual performance and are the best of the best.


But with newcomers battling to wear this heavyweight belt, can Brian Gavin live up to his promise of cut perfection? Or have other brands surpassed his gold standards? Let’s have a look!

We’re going full-on geek in this review and thoroughly look at the deciding factors of the hearts and arrows diamond’s beauty. Now, I have randomly chosen three H&A diamonds from Brian Gavin’s signature series. Let’s call them Diamond 1Diamond 2 and Diamond 3. You can find the proportions of the diamonds below:

Let’s begin with the basics! As you might have read in my post about the round cut diamond, the perfect proportions for a round cut are the following:


Perfect diamond proportions


Now, the suggested proportions for Super Ideal diamonds are already very strict, and in fact, they are even stricter than GIA and AGS’s standards in grading a diamond with the best cut. What’s striking is that all the diamonds above match the Super Ideal proportions without a slight variance!

Please be aware that AGS uses the terminology “pointed” for a culet whereas GIA uses “none.” It is the same, and it means that the culet is a finely sharpened point and not a flat surface. Otherwise, the culet could appear to be an inclusion.

The next step is to have a look at the Idealscope images of each diamond:

Diamond 2 has a small inclusion as this is a SI1 graded diamond. However, Brian Gavin only chooses such diamonds among their signature hearts and arrows diamonds that are eye-clean. Therefore, it’s a better idea to select a lower clarity grade as it will be much cheaper and surely eye-clean!

Other than that, there is no light leakage in any diamond, and the light performance of every single diamond seems to be perfect. (In case you don’t know how an Idealscope image works, please read my post on Idealscope and ASET images.)

The bottom line is that the fewer white spots the Idealscope image displays, the fewer points of light leakage can be found in a diamond. Thus, the more light gets returned to the viewer’s eye and the more sparkle the diamond exhibits. In usual diamonds, you can always find some white spots of light leakage:

ASET Images for Brian Gavin Signature Hearts and Arrows Diamonds

What you are mostly looking for in an ASET image is lots of red/orange because this is where light is returned to the viewer’s eye. The blue color just adds contrast while the green color is for areas that are less bright or where the light is coming from the environment. It’s normal to have some green areas on the verge of the diamond.

The green dot in the middle is caused by the reflection of the table facet on the pavilion facets. But the color that you don’t want to see is the white color because it symbolizes light leakage.

Now, the second diamond does have tiny whiter spots near some blue pavilions. This means that there is very little light leaking through the diamond. To be honest, it would be exaggerated to call it real light leakage, but the ASET image, in this case, would show you that diamond 2 doesn’t perform as good as diamonds 1 and 3.

To give you an idea on what you can expect from diamonds with a “Very Good” cut grade, just have a look at the diamonds below:

All in all, the Idealscope and ASET images provided by Brian Gavin make it fairly easy for you to choose a diamond with superior light performance. Furthermore, you can compare different diamonds with the top-notch light performance to each other to truly choose the best diamond possible.

Brian Gavin Signature Hearts and Arrows Diamonds Viewed through a H&A Viewer

Now, this tool allows us to view a contrasting pattern that makes it relatively simple to see the symmetry of a diamond:

In my post about hearts and arrows diamonds, I described how you could distinguish between near and true hearts and arrows diamonds. And with the images above, I can say, without a doubt, that these 3 diamonds are all true hearts and arrows. The symmetry of the H&A patterning is flawless!
