Big Diamond Rings Brian Gavin 8.10 carat Signature.

Big Diamond Rings from Brian Gavin.

"I'm wondering what kind of big diamond rings people in the jewelry business might get to see. I'm looking for a big diamond ring! Which is something I'm hoping you'll help me search for?"

"As a result, I've been searching to see who offers the biggest diamond rings online. I found this 25.03 carat, G-Flawless, GIA Excellent cut on Enchanted Diamonds. What do you think of it? Have you ever seen a 25 carat diamond before? I'm not really looking for a diamond this big, but a girl can dream, right?""

"I wonder how a big diamond ring like this will look. When shopping for big diamond rings, should I adhere to the same proportions you recommend for smaller diamonds?"

"Realistically speaking, we're probably looking for something about half this size. Where would you look for big diamond rings? While size is important to me, I don't want to sacrifice the sparkle factor. In terms of other things, I think that clarity is more important to me than color."

Notice: The original inquiry for this article was written before Enchanted Diamonds declared bankruptcy. Regardless of their fact, it sets the stage for us to talk about the exciting subject of big diamond rings.

How Big Should a Diamond Engagement Ring Be?

Big Diamond Rings Reviews Enchanted Diamonds.

25-Carat Big Diamond Ring from Enchanted.

This 25.03 carat, G-color, Flawless clarity, GIA Excellent cut from Enchanted Diamonds would be something to see! According to the GIA Laboratory, the diamond measures 18.85 × 18.78 × 11.57 millimeters.

In that case, the average outside diameter is 18.815 millimeters, which is slightly larger than a penny. Can you imagine what that kind of big diamond ring would look like on your hand?

I've seen lots of big diamond rings, and I'll share my favorite story with you momentarily. First, let's review this big guy. Because the diamond is off-kilter in the clarity photograph, we can't see how light reflects this diamond.

Under those circumstances, we can only estimate how this diamond is going to perform by the numbers. The 40.8 degree pavilion angle should produce a high volume of light return.

At the same time, the 35.0 degree crown angle should create a virtual balance of brilliance and dispersion. If you are serious about buying this for a big diamond ring, we should request the following reflector scope images:

We'll use those images to judge the degree of optical precision and judge the degree of light leakage.

Where to Buy Big Diamond Rings:

RARE by Brian Gavin Big Diamond Rings.

Big Diamonds from RARE by Brian Gavin.

All of the preferred vendors I work with are likely to have big diamonds from time to time. In that case, it makes sense to search all of them and consider all the options.

However, it is also important to realize that big diamonds often exist as private inventory. That means that they are not likely to appear in the virtual list most diamond dealers publish online.

Sometimes, big diamond producers don't list them on the multiple listing services we use to trade globally. One of the advantages of having 35+ years in the diamond business is knowing where to find them.

RARE by Brian Gavin is a division that specializes in sourcing big diamonds for their clients. I also suggest that you search here for big diamond rings:

When it comes to big diamonds, you never know which dealer might have the exclusive listing rights online. In that case, you might miss an opportunity if you don't exhaust all the options available.

It would be best if you also took advantage of our free diamond concierge service. We can search the MLS and turn a few cutters upside down to see what falls out of their pockets. You'd be amazed by what I've seen those guys pull out of a front shirt pocket at a trade show!

How to Propose with a Big Diamond Ring:

All right, I suppose that this is as good a time as ever to tell you my favorite big diamond ring story! As with all good fairytales, we should probably start with Once Upon a Time.

After all, that's how all good stories begin. My late wife Robin and I were walking through the aisles of the JCK Trade Show in Las Vegas. It's the most famous jewelry trade show in the world.

Needless to say, that there are plenty of big diamond rings to gawk over. However, it's still pretty rare and exciting when you get the opportunity to see massive diamonds.

Those of you who knew Robin will remember that she attracted attention wherever she went. She was a tall, 5′ 7″ blonde bombshell, dressed to the 9's and dripping in diamonds.

And as if that wasn't enough, she wore solid 14k custom-made, long gold fingernails striped with diamonds on all of her fingers. As you can imagine, she was a sight to see and drew lots of attention.

She Wore Big Diamond Rings!

On the index finger of her right hand, Robin wore a pear-shaped diamond weighing 5.75 carats. She also wore a 2.50 carat marquise next to that and a cluster of big diamonds cascading down her pinkie finger.

Robin wore all of that on her right hand. On the left, a 2.75 carat pear-shaped diamond adorned her engagement ring. She wore that along with a 3.75 carat princess cut diamond on the index finger.

Around her neck hung a princess cut diamond weighing 5.10 carats. It was bezel set alongside a raceway of round diamonds. Interestingly enough, she wore three-quarter carat super ideal cut diamonds as earrings.

Picture Her Standing in the Middle of the Aisle at JCK:

Actually, we were both standing in the middle of the aisle at JCK, talking with a couple of our primary suppliers. When suddenly, they got this look of great concern on their faces.

They began to straighten out their suits, dusting off any lint that might be floating around in the air. Then, they looked at Robin and said, "Robin, we need a big favor," with this pleading look on their faces.

"Please don't speak. Whatever you do, please don't speak!"

As you might imagine, this caused Robin to ask more questions than ever! At the same time, we began to turn around to see who was coming up behind us.

"Don't turn around!" they blurted out simultaneously. And once again, with that pleading look in their eyes, they begged Robin not to speak a single word. "Not one single word! Please, Robin!"

What happened next is shocking!

Needless to say, that Robin had a bit of a reputation for being outspoken. In a diamond world which men largely dominate, she had scratched and climbed her way to the top.

That is why our friends were hoping and praying that she'd be quiet. Unbeknownst to us, we were about to meet one of the largest producers of big diamonds! We later learned that he produces nothing less than 10-carats.

Picture this awkward moment of silence. Then our friends start babbling something rapidly in Hebrew while extending their hands to the guy walking up behind us. We turn just in time to see him wave them away dismissively, and then he turns his attention to Robin.

He looks her in the eyes for a moment and then extends his right hand out to her, palm down, fingers closed. She raises her right hand out to his, palm up and open. Then, he drops a 25-carat pear shape diamond into her hand and says, "I give you this. You marry me!" And it didn't sound like a request.

25-carat Big Diamond Rings:

Imagine Robin standing there in the middle of the aisle at JCK, bouncing this 25-carat diamond in her hand! She's just standing there, bouncing the diamond around in her hand, clearly contemplating her options.

One of which might have been whether to divorce me, right there on the spot! As you can imagine, our friends were standing there speechless! It made their earlier request for Robin to hold her tongue even funnier.

Meanwhile, the diamond cutter with the big diamond rings is just standing there patiently waiting. He looked like a fat Cheshire cat with canary feathers sticking out of his mouth if memory serves correctly.

Best Proportions for Big Diamond Rings:

8.10 carat, Brian Gavin Signature Diamond.

The best proportions for ideal cut diamonds are the same regardless of size. Remember that diamonds are a 3-dimensional model. In that case, it's best to adhere to our five-minute diamond buying guide irrespective of carat weight.

Whether you scale the size of that model up or down, the ideal proportions will always be the same. All of the diamonds in this article have ratios within what I consider to be the sweet spot! The primary difference between them is the degree of optical precision.

If you're looking for the very best light performance for your big diamond rings, then you'll insist on hearts and arrows. Look at the hearts' pattern of this 8.108 carat, J-color, VS-2 clarity, Brian Gavin Signature round diamond.

Consequently, this is the diamond in the feature image at the top of this page. I took this photograph of that same diamond on a mini-pool table earlier this year.

It appears to sparkle magnificently even under fluorescent office lighting! In that case, imagine how spectacular it looks dancing in actual sunlight! No wonder it's the inspiration for the Brian Gavin 810 ring builder.

Search Blue Nile for Big Diamond Rings:

Blue Nile Big Diamond Rings 10.96 carats, H-color, VVS-2 clarity.

10.96 carats, H, VVS-2 clarity, Blue Nile Diamond.

Blue Nile is a popular source for big diamond rings. No doubt about it, the buying power of this behemoth gives them a powerful reach. They have one of the largest virtual inventories of big diamond rings online.

Conversely, Blue Nile boasts the most extensive collection of GIA-graded diamonds online, but most of them don't meet my selection criteria. As that may be, you should still check them out because they usually have a few worth considering.

Take this 10.96 carat, H-color, VVS-2 clarity, GIA Excellent cut round diamond from Blue Nile, for example. It has a pavilion angle of 40.8 degrees, which should produce a high volume of light return.

At the same time, the 34.5 degree crown angle produces a virtual balance of brilliance and dispersion. The proportions are right smack-dab in the middle of the spectrum for the zero ideal cut rating.

In that case, the proportions set the stage for a spectacular light show. However, we need to see the following reflector scope images to judge the performance accurately:

Big Diamond Rings Make the World Go 'round:

James Allen Big Diamond Rings review, SKU 2212545, GIA 2175944539

Big Diamonds from James Allen.

Do you remember the song "Money makes the world go-'round?" Well, that's what pops into my head when I look at this 10.09 carat, E-color, VS-2 clarity, GIA Excellent cut round diamond from James Allen.

This puppy rings in at $766,390.00, and that certainly makes my world go-'round! Talk about a diamond big enough to have its own solar system! Seriously! This diamond has an average outside diameter of 13.99 mm.

According to the Daily Med, a standard size, 325-milligram aspirin measures around 14 mm to put this in perspective. So the next time your wife says, "Not tonight, honey, I have a headache," what she needs is a big diamond ring!

Learning to pay attention to those subtle hints is the secret to any good marriage. Of course, there will not be anything subtle about a diamond that measures 14 mm in diameter.

Buying Big Diamond Rings by the Numbers:

The 40.6 degree pavilion angle on this diamond should create a high volume of light return by the numbers. At the same time, the 35.0 degree crown angle produces a virtual balance of brilliance and dispersion.

Of course, there's only so much that we can tell about a diamond by the numbers. That is why you should insist on seeing ASET and other reflector scope images before making a substantial investment.

In this case, there appears to be a little obstruction adjacent to the arrows pattern under the table facet. We'll want to get a better idea of the extent of its effect upon the light performance.

Don't Buy Big Diamond Rings In the Dark:

Brian Gavin Diamond Details Page.

Buying big diamond rings without the insight that reflector scope images provide is like buying diamonds in the dark. There is only so much that we can tell about a diamond by the numbers.

Although that may be true, people buy big diamond rings every day without knowing anything about them. Perhaps they blindly assume that a diamond is going to be beautiful because it's GIA Excellent cut?

Unfortunately, few people realize that the AGS Ideal & GIA Excellent cut grades represent a range or spectrum of performance. In that case, there is a low, medium, and high end of the spectrum.

If you're going to invest in big diamond rings, don't you think it makes sense to know all that there is to know? Trust me when I tell you that a diamond clarity image is not sufficient to make this kind of decision! The diamond details page for this Brian Gavin Signature diamond provides everything necessary to buy with confidence:

  • Diamond Clarity Photograph.
  • High Resolution Video.
  • ASET Scope image.
  • H&A Scope image.
  • Ideal Scope image.

In short, Brian Gavin provides all the details necessary to know that this diamond is Drop Dead Gorgeous. Under those circumstances, you can buy with confidence because there is no guesswork.

But, wait, because this is an important point:

It's not because Brian Gavin provides these images that lead me to believe the diamond is spectacular.

Any fool can put a diamond under a scope and snap a few photographs. That doesn't necessarily mean that the diamond is going to perform well. It only means that somebody took a photo of the diamond through a reflector scope.

Similarly, staring off into space doesn't mean that you're going to walk on the moon. Likewise, buying lingerie from Victoria's Secret doesn't make you a supermodel any more than claiming to be one on Instagram. #BURN.

In the same way, snapping a few pictures of a diamond through a few scopes doesn't make it Hearts and Arrows. Sorry to be so blunt, but I believe in calling it like it is.

People send me reflector scope images for poorly cut AGS Ideal and GIA Excellent diamonds all the time. Don't assume that a diamond well-cut simply because the vendor provides a few scope images.

Why Don't More Dealers Provide ASET and H&A Images?

Conversely, there is a good reason why online dealers provide reflector scopes for some of their diamonds and not others. They know that most of the diamonds they sell are poorly cut and won't withstand scrutiny.

Although that may be true, more of them will provide images for their diamonds if customers insist upon them. As that may be, you must know how to interpret the images correctly for them to be helpful.

In that case, I recommend reading this article on contrast brilliance and this one on obstruction. It is also helpful to know how to interpret the different colors of an ASET. You can take advantage of our free Diamond Concierge Service and take the guesswork out of the equation.

Big Diamond Ring Performance Issues:

Light Performance of AGS Ideal vs GIA Excellent vs Super Ideal Hearts and Arrows diamonds, as compared to Porsche 911 models

Porsche Performance Class.

What kind of light performance do you want from your big diamond rings? Would you believe that most people probably don't give it much thought?

Perhaps they wrongly assume that AGS Ideal and GIA Excellent means that a diamond is the best. Or, they possibly don't realize that each cut grade represents a range of possibilities and performance.

The analogy that I usually rely upon is a comparison of the different models of the Porsche 911. Consequently, I think that most people would be happy with the performance of the baseline model.

By that, I mean a standard Porsche 911 non-turbo that just rolled off the production line. Consequently, that is how I view most GIA Excellent cut diamonds with proportions in the middle of the spectrum.

Conversely, diamonds in the ideal classification exhibit a wide range of performance, so some perform better than others. In that case, a small percentage deliver the light performance of a Porsche 911 Turbo.

An even smaller number, like 0.001%, will perform like a Porsche GT3 RS. Those are the ultra-super ideal cut diamonds found in the Black by Brian Gavin Collection. Simultaneously, there are other Hearts and Arrows diamonds that fall somewhere in the middle.

Black is the Clear Choice for Big Diamond Rings:

It should be evident that I'm a fan of Black by Brian Gavin diamonds. First, you should know that Brian Gavin is one of my original mentors in the diamond business. He also used to produce diamonds for our private label hearts and arrows collection.

Consequently, we were buying A Cut Above™ hearts and arrows diamonds from Brian Gavin back in 1998. Under those circumstances, I know what to expect from every Brian Gavin Signature diamond.

In other words, I have the confidence built by experience to know that every Brian Gavin Signature diamond is drop-dead gorgeous! But you don't have to take my word for it because the images speak for themselves.

Every Brian Gavin Diamond that I've ever seen looks spectacular and exhibits the highest light performance. My girlfriend lost her mind when she saw her first Black by Brian Gavin diamond.

My GF's Initial Reaction to Black by Brian Gavin:

My girlfriend and I visited Houston, Texas, in April of 2017. I spent most of the week at Brian's office. Meanwhile, Lety did her part to fertilize the local economy.

Consequently, Lety grew up in Taxco, Mexico, and worked for a manufacturing jeweler making jewelry for high-end stores. In that case, she's seen her fair share of diamonds, but she'd never seen anything like Black.

In hindsight, I should have set up a video camera for posterity. Lety lost her mind when I set a few Black by Brian Gavin diamonds on a sorting tray.

I was making a 3-stone comparison for a client and didn't account for Lety's reaction. She was sitting at the far end of a conference table on the other side of the room, flipping through some trade magazines.

I set the three diamonds out on a sorting tray and spun them this way and that to watch them play in the light. Suddenly, Lety was pressed up against me and exclaiming:

"Wow! Oh, Wow! Wow! Oh, Wow!"

Then, I was her head between mine and the sorting tray. It was as if she was in a strange hypnotic trance. Seriously, she was gone. She just stood there looking at those diamonds and repeating the same phrase over and over again.

Given that the subject of this article is "Big Diamond Rings," you might think that these were big Black by Brian Gavin Diamonds. However, the three diamonds I was comparing were in the 1.30 – 1.35 carat range.

The funny thing is that we were sitting in the conference room, which has overhead fluorescent lighting. On that note, I suggested that we walk the diamonds over to the window so that Lety could see them in the sunlight.

It was at this point that everything happening at Brian Gavin Diamonds came to a screeching halt! Because Lety let out another loud rendition of "OMG! Oh, Wow! Wow! Oh, Wow!"

Which quite honestly made me feel slightly inferior. Because let's face it, I've never quite heard Lety have that kind of reaction to anything before. Yea, that's right, go ahead and laugh.

Does Size Matter with Big Diamond Rings?

Every woman is different, so when you discover what works, you should probably do it again. In that case, I took Lety to the vault and whipped out the 8.10 carat Brian Gavin Signature diamond.

That caused the same reaction as before, but Lety did not say anything about the size. Given that fact, I can only conclude that size doesn't matter when it comes to satisfying her desires.

Lety's reaction was the same for the 8.10 carat and smaller Black by Brian Gavin diamonds. That proves that when it comes to diamonds, it's all about sparkle factor and light performance.

In other words, I could present either of these options to Lety:

The odds are that she will appreciate them both equally. Of course, you realize that we're talking about the light performance. A woman's preference for size is a relative concept that is largely a matter of perception.

Conversely, one woman might consider three-quarters of a carat to be big, while another might prefer 10.00 carats or more. In my experience, most women feel anything larger than 2-carats to be a big diamond ring. Of course, it is essential to consider the mounting since that completes the package.

Big Diamond Rings Cut-to-Order:

As stated previously, it can be difficult to find big diamond rings online. Many diamond cutters do not list large diamonds in the multiple listing service for privacy reasons.

At the same time, the effects of COVID have an impact on the production cycle. The global inventory of big diamonds is smaller for that reason. In that case, the best way to ensure your satisfaction is to have the diamond cut-to-order.

Ordering a diamond cut-to-order is the best way to guarantee the characteristics you desire. Brian Gavin is the best option since you're not likely to find that kind of sparkle factor elsewhere.
