Brian Gavin is a 5th generation diamond cutter who is well known for his signature lines of ideal cut diamonds. With humble roots from learning the craft in his family business, Brian Gavin went on to develop the science and perfected the art of creating diamonds with unprecedented performance & sparkle.

In the early 2000s, Brian Gavin was also a pivotal figure in establishing and promoting the standards for hearts and arrows grading. Till date, this set of standards is still widely adopted in the industry.

Since the launch of his business, Brian Gavin has developed a series of super ideal cut diamonds in popular shapes like the round brilliant, princess cut and cushion cut.

And there are still no signs of him slowing down!

What’s really exciting is that Brian Gavin is continuously pushing boundaries by developing new cutting techniques and crafting diamonds optimized for visual performance.

Brian Gavin Diamonds Review – List of Product Lines

In order for us write an indepth review of, we had to break down the analysis for their individual product lines. If you are in the market for a specific diamond shape or product, feel free to jump directly to the section that interest you.

Brian Gavin Signature Hearts And Arrows – When a 57 facet round brilliant cut is cut to ideal proportions and high precision, a crisp hearts and arrows patterning can be observed in the face-up and pavilion views. We perform an analysis on Brian Gavin’s signature H&A diamonds to see how they fare.

Brian Gavin Black – The pinnacle of Brian Gavin’s diamond cutting career. The Brian Gavin Black diamonds have ancillary angles (star, upper girdle and lower girdle) that are engineered for extreme light performance.

Brian Gavin Cape – Brian Gavin created this specifically for people who want to buy large diamonds without the high costs of owning one. This signature line features ideal cut diamonds in the M-R color range which offers better bang for your buck.

Brian Gavin Blue – The Blue diamond line is your opportunity to buy an ideal cut diamond at a discount because of unwarranted paranoia in the industry. Specially curated by Brian Gavin, the blue fluorescence found in these diamonds is not only a cool feature but also helps to make a diamond whiter!

Brian Gavin Ideal Cut Princess – Princess cuts are the 2nd most popular diamond shapes in the market. In his signature princess diamonds, Brian Gavin utilizes a 3-chevron configuration to create a perfect balance between brilliance and sparkle.

Brian Gavin Cushion Cut Hearts And Arrows – Brian Gavin has basically incorporated the best aspects of round brilliant faceting into his patented cushion cut diamonds. When it comes to cushion cut diamonds, I can tell you that there aren’t many in the world that can match the light performance exhibited by these stones.

Ring Setting Quality And Custom Designs – Aside from high performance diamonds, Brian Gavin also has more than 30 years of experience in custom engagement ring designs. We will take a look at the level of craftsmanship and quality you can expect from his settings.

Why You’ll Love Shopping at Brian Gavin Diamonds

As an engineer by training, I’m taught to look at facts and hard tangible data when performing assessments instead of blindly believing claims. That’s how I personally buy diamonds and I advocate that you do the same as well. Remember, you should never buy blind!

Unlike many other online vendors that base their entire business around a virtual inventory (don’t own the diamonds nor seen them in person), Brian Gavin owns and curates his inventory with strict quality control measures.

For the discerning shopper, makes it easy for you to perform a thorough analysis of their diamonds. From determining eye-cleanliness to assessing performance, a complete set of data is provided in a concise manner.

From a typical listing, you get to see the actual diamond under normal office lighting (fluorescent) and how it interacts with intense lighting conditions (shopping mall and sunlight).

I’ve made some screenshots below and I strongly encourage you to click on the listing to interact with the videos yourself. Once you do so, you will realize how intuitive the website is and with a little effort, you can scrutinize details of the diamond.

When it comes to analyzing light performance, Brian Gavin provides ASET, Idealscope and hearts patterning images for their H&A diamonds. This makes it straightforward for the discerning consumer to know exactly what they are buying.

Are There Any Complaints or Stuff I Don’t Like in This Review?

If there’s one thing I could legibly complain about, it is the small inventory size that Brian Gavin has at any point in time. You see, Brian Gavin’s diamonds are top notch in cut quality and there’s a limited supply of them to meet strong consumer demand.

Because of their popularity and the rate they move off the inventory, it can sometimes be difficult to find a diamond within a certain set of specifications. For example, if you are looking for a 1 carat D/IF diamond due to symbolic reasons or a 1.2 carat G/VS2 to get better value for money, you may have a hard time tracking one down.

To deal with this issue, Brian Gavin has launched an Advance Selection range where you have the option to “pre-order” a diamond with guaranteed light performance (AGS 000), color, clarity and minimum carat size. This effectively widens the range of diamonds available for purchase.

And if you still can’t find a diamond based on your specifications, the custom-cut diamond program would be something you may want to consider. Now, don’t let the term “custom cut” scare you away from starting a project with Brian Gavin.

There are no additional costs compared to another diamond that you can buy directly off the inventory. The difference is that the return policies are slightly different and the lead time may take up to 1 month for delivery.

  • If you find a diamond that fits exactly what you are looking for, DON’T PROCRASTINATE. Otherwise, you will end up disappointed when someone else purchases it. If you do need some time to think about the purchase, get in touch with their support via live chat or email to place the diamond on hold.

      Thanks for this awesome website! I really appreciate the amount of information that one can learn just from visiting your site alone.

      I have a couple of questions about Brian Gavin’s signature cushion cut diamonds. My husband and I are looking for a 15th year anniversary present and Christmas came early for me. How do they compare to the regular diamonds and are they a good buy in terms of value?

    2. Paul Gian-

      I am assuming you are asking about the newly released series of hearts and arrows cushion cut diamonds. This is a specially patented cut by BGD (aka Brian the Cutter) and their unique selling point is the AGS 000 certification and optical patterning for the fancy cushion shape.

      Having looked through their inventory, I think there is no argument that these are beautiful diamonds. The light performance grading by AGS is testament to that. However, I am not particularly impressed by the cushion hearts and arrows for one reason – lack of consistency in craftsmanship.

      Unlike Brian Gavin’s other signature line of diamonds, I see a lot of variation in terms of precision cut quality and even optical performance. I don’t say this easily without the technical data to backup my views.

      Checking the patterning on the pavilion side of the 5 random stones, it isn’t hard for a layman to see obvious differences between each stone.

      Likewise, the ASET imagery of another 5 random selections also shows clear discrepancies.

      From my point of view, if I am paying a premium for cut quality, I expect the best and nothing less. The newly released cushion cuts don’t fulfill my own Nazi-styled cut standards. Coming from Brian Gavin’s selections, this disappointment can be almost considered blasphemy as I was always a fan of BGD.

      Perhaps the lack of quality control could stem from this line of diamonds being new and inadequately tested. When I do manage to get my hands on one of these diamonds, perhaps I will do a more thorough write up on it.

    4. White Flash vs Brian Gavin-
      August 27, 2015 at 11:23 am

      Does Brian Gavin Diamonds have a showroom at their location? Also, what’s the difference between BrianGavin and WhiteFlash? You seem to recommend both companies highly but if it comes down to it, which company is better?

    5. Paul Gian-
      August 27, 2015 at 11:29 am

      They do operate a showroom at their address: 7322 Southwest Fwy #1810, Houston, TX 77074, United States. It is best to call in advance and set an appointment as they can get really busy at times and it is also advisable to check if they have available stones within your specifications.

      With regards to White Flash and Brian Gavin, it’s hard to say who’s better. Both vendors sell extremely well cut diamonds with unbeatable light performance. The main differences lie in the type of designer settings offered. For example, White Flash carries Verragio & Tacori while Brian Gavin carries Scholdt.

      It is also worth noting that Brian the Cutter recently patented their signature line of cushion hearts and arrows diamonds which you can’t find anywhere else. BGD also offers a special line of ideal cut blue fluorescence diamonds which are out of this world.

      Really enjoying your series Beyond 4Cs, thank you. I’ve been looking at brown diamonds on the Leibish site. They seem transparent and I like their descriptions. Any comments on them?

      Hi Paul,
      I’m looking for a emerald cut diamond 2-3 carats. Where do you recommend to look for. It seems like emerald cut is limited.

      I also check out Brian Garvin’s website for round shape. It seems their diamonds are more expensive and also come in lower colors such as I, J. as compare to Bluenile and James Allen’s. Do you have any comparisons of Blue Nile vs Brian Gavin or James Allen vs Brian Gavin?

    10. Paul Gian-
      January 5, 2018 at 12:50 am

      That is right. They are slightly pricier but I would say you aren’t necessarily comparing apples to apples. Brian Gavin’s diamonds have better cut precision than the Astor signature line and True Hearts line in general.

      I hit a home run when I purchased a 1.1 ct. (VS2, F, round) diamond in 2018 from Brian Gavin’s Black collection. The stone size was perfect for my fiance and–to use another sports analogy–punches well beyond its weight class. I couldn’t be happier with the diamond and the entire transaction. The stone is AMAZING and far beyond our expectations. Its brilliance is also unlike any we saw at local jewelers and it outshines most diamonds we see others wearing (and who probably paid a heck of a lot more). My fiancee is continually shocked by the compliments she receives from strangers. The customer service process was also smooth. The BG rep provided helpful guidance, patiently walked me through the selection and purchasing process, and was never pushy or “salesy” in any manner. I wouldn’t hesitate to refer my friends to Brian Gavin.

      We purchased a .72 G VS 2 Brian Gavin Black round brilliant for my engagement ring in 2016 and two BG black .40 G VS 2 round brilliant for earrings last month. I have always been more than pleased with the service and care from them.
