15 carats is one diamond ring which clocked in at $4 million – there were plenty of people trying to find fault with it. It’s too big. It’s too lavish. It’s too much. But eventually, even her biggest critics had to concede that the diamond was beautiful. Because even the biggest, most luxurious diamond rings don’t have to be outlandish. With the right setting, the right cut, and the right care, a 15 carat diamond ring can be quietly, undeniably perfect. And if you’re in the market for a 15 carat diamond, specifically, then we’re here to get you there.
Before we dive deeper into the specifics, here are some practical tips to help guide your decision-making process:

Ordinarily, we let you know a little more about the diamond and the price before jumping into the 4Cs, but let’s be honest, you already know that the price is going to be big. That’s a given. What’s not a given is buying a diamond that justifies the price. The most important thing to do, in this case, is jump straight to the 4Cs – because they’re important. The bigger the diamond is, the more chance there is of noticing any flaws, so if you don’t know what you’re looking for, you need to get in the know.
The 4Cs are as follows: carat, clarity, color, and cut. In the case of the carat weight, a 15 carat diamond is extremely rare, making it a highly sought-after commodity. This is also what shoots up the price. In general terms, the higher the carat weight, the more expensive the diamond is going to get – however, the cut also plays a crucial role, which we’ll get into later.

When it comes to clarity, the Gemological Institute of America (GIA) grades the diamond on a scale from Flawless to Included. Sadly, because of its size, a 15 carat diamond is more likely to have visible inclusions, but that doesn’t mean it’s a given. If you’re looking in the range of VS1 to SI2, you will still be able to find gorgeous 15 carat diamonds that let the line shine through and sparkle beautifully.

The color, too, might be more noticeable. Once again, this is graded by the GIA, with the scale ranging from D (colorless) to Z (light yellow or brown). Larger diamonds like the 15 carat can often display color differently to smaller diamonds, with the potential to be more pronounced, but the perception, in this case, can be influenced by clarity and cut.

Now we get onto the cut – perhaps the most important ‘C’ for the 15 carat diamond. The cut determines how light will interact with the diamond, but a large diamond that has not been adequately cut could lose some of its deserved sparkle. When looking at a 15 carat diamond, you need to take into account how light reflects internally, and whether the reflection and refraction make it even more dazzling. Akin to this, a well-cut diamond will appear larger than its actual carat weight, so even though you’ve already gone for a bigger diamond, you can make its impact even more substantial! Once again, we have more information on the cut and its importance if you follow this link.
Before we go any further, we should talk about a common occurrence amongst diamond shoppers, especially when it comes to larger diamonds. Because the weight difference is relatively minimal, it’s easy to wonder whether you really need a 15 carat diamond, or drop down to 14 carats. Vice versa, you might wonder why you should stop at 15, and perhaps move to 16, 17, or even 18. There’s no right or wrong answer to whether you should move away from the 15 carat, but there are some distinct differences between each weight that you should know about.
The first thing you should note is that this isn’t just about size. While the differences between the 15 carat and 14 carat might be minimal to the naked eye, the minimal size decrease also decreases the overall presence and visual impact of the stone. The sparkle will be less, the brilliance and the fire slightly less pronounced – although a lot of this will depend on cut, color, and clarity. That being said, the price should indeed be lower, or you might be able to pay the same kind of price you were going to with the 15 carat, only with far better grades.
On the other side of the coin, going larger might not exactly mean you’re buying better. For a 16-18 carat diamond, you might be paying predominantly for its largeness and opulence, while sacrificing a portion of your budget for the other 3Cs. We don’t think it’s a bad idea to investigate, of course – the more opulent, the better! – but it’s important to take everything into account when making your decision.
When it comes to the price of a 15 carat diamond, the 4Cs are going to play a big role. For instance, if you were to buy a diamond with D color, Flawless clarity, and an Excellent cut, on average, you’d be expected to fork out between $1.5 million and $3 million. This is why it’s important to examine each grading and balance out what you want and what you feel you can sacrifice.
As we mentioned before, no diamond has to be Flawless. No diamond has to have a D color. When you start reaching that grade, the inclusions and blemishes – or lack thereof – become so minimal that you can’t notice them without a microscope. And we’re pretty sure your SO won’t be whipping one out when you propose! So when you’re trying to understand price variations, look at what you can notice with the naked eye, and make sure to get as much advice as possible.
Another aspect of ring shopping that will shape the price is the setting you go for. This is a part of the process that plenty of people gloss over, but it’s so important to get right, especially if you’ve gone with a 15 carat diamond that you want to show off.
Let’s start with your choice of metal. At the end of the day, this will come down to your personal preference, style, and lifestyle. For the most part, however, platinum is a solid choice for a 15 carat, especially if you want something durable. While it’s the most expensive metal option for diamond settings, it is a premium choice, and it’s perfect if you want to invest in quality and longevity. White gold, yellow gold, and rose gold are less expensive options and, coupled with a great setting, they can provide beautiful houses for your diamond. But they might require greater care if you want to prolong their durability.
There are so many settings to choose from, each one of which offers something a little different. Some of the more intricate settings include the halo or pave settings, which can perfectly accent stones and add a touch more glamour. Simpler settings like the solitaire or three-stone setting, however, are often more popular. When it comes to a stone like this, you don’t need to worry much about how intricate or complex the setting is – the diamond is the main showpiece, so the simpler the better. But as we mentioned previously, it all comes down to your personal preference.
There’s no denying that the 15 carat diamond could be the perfect option if you’re looking for something extra special. It’s glamorous, dazzling, and quite simply, it’s beautiful. To part with that much money, however, you need to make sure it’s going to the right place and the right stone. If you need more inspiration, try to research more about the 4Cs and price variations you can expect to come across. Look at 15 carat diamonds being worn, and work out how the setting complements – or doesn’t complement – the stone itself. You don’t need us to tell you, as we’re sure you know already, but this decision is an important one. So do everything you can to make it perfect!
