Everything you need to know before buying a 6 ct diamond for your ring
A 6 carat diamond with passable grades can cost between $15,000 to $80,000 per carat.
6 carat diamonds are exceptionally large, and equally beautiful assuming a high grade in cut, color and clarity. Thus 6ct diamonds are quite rare and quite expensive. Have a look at our diamond calculator to explore the price differences.
For a high-quality 6 carat diamond with a color rating of G or above and VS2 or better for clarity, you can expect to pay over $150,000, which works out to $25,000 per carat (depending on the shape). On the higher end, a 6 carat round diamond graded at D color and FL (flawless) clarity. Such an exquisite diamond can be priced at $400,000.

If you’re in the market for a 6 carat diamond ring, following certain recommendations on GIA certified grades will ensure you get the best value for your purchase. We advise sticking to Excellent grades for cut on the GIA scale, G to I for color, and VS1 or VS2 for clarity.
A high-quality 6 carat diamond like this one from Blue Nile commands attention anywhere it goes. The fire and brilliance of a diamond this size is unique and immeasurable. However, a 6 carat diamond with poor grades in areas such as cut and color will come up short, and you’ll end up overpaying for a ring with inferior beauty.
When you’re ready to purchase a 6 carat diamond ring, restrict your search to reputable vendors such as James Allen, Blue Nile and Abe Mor. Additionally, contact us and we’ll be happy to guide you through your search for the perfect diamond ring.
6 carat diamonds are exceptionally rare, so you are unlikely to find one (especially a diamond with a high-quality cut) in a local jewelry store.
New York City-based Abe Mor Diamonds is a great option for large and rare diamonds. They specialize in helping their customers find high-quality, rare diamonds that are in short supply from other vendors.
The two premier online diamond retailers, James Allen and Blue Nile, are also fine options to look for a high-quality 6 carat diamond. These vendors offer the most extensive range out of any online jewelry stores, including a small selection of diamonds 6ct and above.
Both these companies offer diamonds that come with the best certification (GIA) and provide imagery that lets you inspect the diamond closely online. These two points are of particular importance when you’re in the market for a rare and expensive 6 carat diamond, as the price difference between different grades is that much bigger. Purchasing a poorly graded diamond may end up costing you tens of thousands of dollars more than necessary.
Other reputable diamond retailers include Brian Gavin Diamonds and Leibish & Co. Their range of clear diamonds 6ct and higher is quite limited though. You are more likely to find several options to choose from by shopping at James Allen or Blue Nile.
If you’re looking for a fancy colored diamond, Leibish are a great option. They offer the best range of colored diamonds, and this extends to a decent range of diamonds 6ct and above, such as this 6.60 carat fancy brownish yellow cushion cut diamond.
Diamond size and diamond carat are often mistaken to be the same thing. The truth is, diamond carat refers to the weight, not the size of a diamond. Each carat is equal to 0.2 grams, thus a 6 carat diamond weighs 1.2 grams.
Its size however will differ depending on the shape and cut of the diamond. A 6 carat round brilliant diamond, the most common diamond shape, has a diameter of approximately 11.70.
A diamond’s surface area, depth, and more contribute to its size. Thus a diamond with a larger table and fewer facets will usually appear smaller, despite being the same carat weight as a seemingly larger diamond of a different shape.
As the GIA explains well below:
“Equating carat weight and size seems like common sense, but it doesn’t always work.” “The way a gemstone is cut affects its perceived size. A poorly cut round brilliant diamond may be too deep or have a girdle that is too thick. Extra weight can be hidden in or below the girdle. Once the diamond is set, you won’t see this “hidden” carat weight, so a poorly cut 1.20 ct diamond may appear to be the same size as a well-cut 1.00 ct diamond. You end up paying for added weight with no added benefit.” Gemological Institute of America (GIA)

The difference between a low-quality diamond and one with exceptional beauty and brilliance is down to its grades for the 4 C’s – cut, color, carat and clarity. As we mentioned in regards to 6 carat diamond prices, a higher or lower grade will result in a significant difference in price with rare diamonds of 6ct and above.
Diamond clarity refers to the appearance of the diamond, and how many blemishes and inclusions are present. A higher grade indicates little to no imperfections.
This is how the GIA grades diamond clarity (best to worst):
Above a certain level, any inclusions are impossible for the naked eye to detect. It’s very hard to notice any imperfections in a diamond with a VS2 grade unless examined closely with specialized equipment. Generally, the highest grade you would want to consider is VVS2. At this grade, you will not be able to notice any inclusions. Any grades higher than this will come at a premium price, for no noticeable increase in beauty.
The difference between one clarity grade and another is just about impossible to tell with the naked eye, there will be a big difference in price. That’s why it’s vital to get the help of an expert when buying a diamond ring of this size. Doing so will help you assess if the diamond’s clarity grade is fair, and ensure you don’t overpay.
“Diamond Shape refers to the outline of the stone (pear, oval, round, etc.). Diamond cut refers to a stone’s facet arrangement. So a shape can be faceted in a variety of ways, or cutting styles.” Gemological Institute of America (GIA)
Beautiful diamonds are available in many different shapes, to fit the taste and hand of the wearer, as well as the ring’s setting. This is true for 6 carat diamonds as well, providing you shop from a store that carries a decent range, like James Allen or Blue Nile.
The shape of your diamond is generally down to personal preference. The round brilliant is the most common shape, and a timeless look that will fit just about any situation. For a more unique look, you might want to go with an asscher, oval, or pear shaped diamond. Elongated shapes have a larger table surface area, which means they appear larger than a round diamond of the same carat weight.
Here are some examples of the beautiful diamond shapes you can find at 6ct and above:
As with clarity, color is a grade given by diamond grading entities and an important thing to consider when buying a 6 carat diamond ring.
The GIA gives each diamond a color grade of D to Z. The D color grade is the highest, representing a completely clear, colorless diamond. Z is the lowest, indicating the diamond has an obvious tint of brown or yellow.
As with clarity, the difference between one color grade and the next (say F and G for example) is barely noticeable to the naked eye. The difference in price, however, is very noticeable. For this reason, it’s important you buy a diamond with a certification from a top grading entity, and that you have an expert inspect it before you purchase.
In most cases, your goal when assessing diamond color is to ensure it appears colorless to the naked eye. The grade itself isn’t what people will notice when they see the ring, only how it looks to the eye. With this in mind, be aware that the ring’s setting influences how color appears. A darker setting, such as rose gold or yellow gold, will contrast with the diamond and can make a lower grade diamond appear whiter than its grade.
Generally, a diamond with a color grade from G to I is the best option for value. Anything higher than this won’t really bring a noticeable difference but will put you into a higher price range. Anything lower will have an obvious yellowish tinge that may detract from the beauty of the ring.
Our goal is to help you get the best ring at your desired price point. When looking at diamonds as large as 6 carats, it’s all too easy to spend a lot of money on aspects of the diamond that are barely noticeable.
You can expect to spend a lot of money on a 6 carat diamond, but with that price tag, you’ll rightfully expect a beautiful diamond. Inspecting the diamond yourself, as well as getting the help of an expert before making your decision, will go a long way to ensuring you get a stunning diamond for a fair price.
To make sure you get fair value out of your purchase, first, stick to diamonds with a reputable certificate. The GIA is the best grading entity out there. Anything else is likely to inflate the given grades, and you may wind up overpaying for a lower-quality diamond.
