Black by Brian Gavin is the pinnacle of Brian Gavin's work. I always wonder how to differentiate between his usual Signature diamonds and his Black collection. Even after talking to him personally, I still can't find a way to best describe it, until recently.
After having some time to think things through, I find that my explanation is pretty simple - Black by Brian Gavin is simply a collection of high quality diamonds that have well-proportioned secondary angles (ancillary angles), which in lower girdle, upper girdle, and star facets. As some of you may know, to find good diamond, the main thing we focus will be the pairing between the crown angle and the pavilion angle, which is something most diamond crafters focus on, according to Brian Gavin Diamonds' explanation. In other words, less focus will be given to the other "not-so-important" facets. But as light reflects within the whole diamond, no matter how minor a facet is, it will somehow play a role in the overall performance, and this is where Brian Gavin focuses on improving.
After dissecting and experimenting with different facets, Brian Gavin manages to come out with a set of proprietary techniques / rules / formula, which is now patented, to optimize the secondary angles to make them perform even better than their Signature diamonds. So naturally, with more care given to the minor facets, the time taken to polish a diamond will definitely be longer, which warrants the slightly higher price. Also, we have to consider the carat weight loss that can incur if he wants to optimize minor facets even when the crown angle and pavilion angle is already very well-paired. Sometimes, this kind of persistency in optimizing a diamond's beauty may actually caused them to earn even lesser because the diamond fails to hit the next magical mark, and this kind of attitude should be well-respected because the man himself cares about his craft above anything else.
Now, with that being said, today, I happened to bump into such diamonds that are optimized for beauty, rather than focusing on hitting the magical mark, which is:
0.497ct G VS2 Black by Brian Gavin Diamond

and
0.492ct G VS2 Black by Brian Gavin Diamond
Just look at their size! It is even bigger than some GIA 3EX 0.5ct diamonds facing-up! And those 0.5ct will be more expensive as well because the magical mark has been hit! For instance, this 0.5ct G VS2 Faint Fluorescence GIA 3EX diamond, which costs approximately RM 6,800.00. However, for both Black by Brian Gavin Diamonds above, the price is RM 5,490.56 (same price for both) using TransferWise. In this case, you are getting a slightly bigger diamond facing-up, with much better cut precision, well-optimized at every angles, at 4 digits cheaper, what is there not to love?
p.s. Personally, I like the 0.492ct more because it is larger facing-up and it has a pairing of crown angle and pavilion angle that I like slightly better.
