How to Buy 6 Carat Diamond Rings

A diamond that has been meticulously cut is a thing of exceptional beauty; whether it’s the sparkle of a modest 0.5ct diamond or a spectacular 6.00ct diamond. An abundance of fire, brilliance and scintillation requires perfect proportions and facet precision to deliver the extraordinary light performance that make diamonds uniquely beautiful.
Six carats is a considerable weight for a diamond – even those who work in the world of diamonds may only come across a handful of truly exceptional 6 carat diamonds every few years. Such impressive diamonds require a particular set of conditions in order to unleash their full capacity for fire and brilliance.
The unwise choice can be costly, but get it right and the results are truly breathtaking.

Diamonds are priced per carat, and price increases exponentially as you move up the carat weight categories (i.e. 1 carat, 2 carat etc). Setting a reasonable budget is the first step, but being aware of your options should be a priority too.
As well as covering the finer details of choosing a 6-carat diamond, this guide will give you realistic expectations. Let’s get into it!

What Is A 6 Carat Diamond?

Loose Diamonds Carat Weight Chart
Though often used interchangeably with size, ‘carat’ expresses the weight of a diamond. While size is dependent on cut proportions and shape, carat is a set quantity. Since one carat is equivalent to 5 grams, six carats is around 1.2 grams.
Our customers sometimes ask us if a six-carat diamond is ‘big’. Yes, a six-carat diamond is much heavier than the average diamond used for engagement rings (which is 1.00ct or less). To put its size in perspective, a round brilliant cut 6-carat diamond typically measures around 11.75 to 12 millimeters in diameter. A 1ct is around 6.5 mm.
This substantial size makes it a standout choice for those seeking a statement piece that exudes opulence.
It is important to know that cut quality will determine actual and apparent diamond size, as well as its brightness and fire.
What truly sets a 6-carat diamond apart is its rarity. Natural diamonds of this size are extremely uncommon compared to smaller carat stones. Natural 6 carat diamonds require specific geological conditions and a precise formation process to grow to such impressive size.
Due to their rarity and inherent beauty, they are considerably more expensive than their lab-grown counterparts. With a focus on quality at the core of the Whiteflash ethos, we have helped thousands of customers find the diamond ring of their dreams - in a wide range of carat weights.

How To Choose A 6 Carat Diamond Using The Four C’s

Generally speaking, in natural diamonds the larger the carat weight the more important the details are as the price increases exponentially. We implore our customers to use our education pages to familiarize themselves with the four C’s or enlist the support of our experts.
A well-balanced combination of carat, clarity, and color with a great cut determines the diamond's overall beauty and value. While there is room for movement among quality grades and personal taste comes into play; this flexibility is limited if you want the most value for your money and dazzle for your diamond.


While it's natural for larger diamonds to exhibit more internal characteristics (inclusions) due to their size, choosing a diamond with a clarity grade like VS2 ensures that these inclusions are minimal. For a 6-carat diamond, a VS (1 or 2) is a beautiful clarity grade, usually ensuring an eye-clean appearance.
Despite the possibility of finding beautiful, eye-clean diamonds with lower clarity grades in smaller carat weights, when it comes to such a precious piece as a 6 carat diamond ring, paying attention to the clarity grade is even more crucial.
However, it's important to note that each diamond is unique, and the location, type, and visibility of inclusions can vary. That's why utilizing our high-resolution imaging and 360-degree videos is invaluable - you can take a detailed look at your diamond to assess its clarity with ease.
Diamond inspection tools allow you to evaluate the diamond's clarity and ensure that any imperfections are acceptable to you. This is an example of how budget and beauty can be balanced.
Lab-grown diamonds typically have fewer inclusions than natural diamonds of similar size and clarity grade. Their growth occurs in controlled environments, where impurities can be minimized during the process.


Firstly, it's essential to recognize that as diamond size increases, the body color becomes more perceptible. For color, an H and above is ideal for a 6.00ct diamond.
For those who are especially sensitive to color (are more likely to notice yellow/brown hues), a G grade is at the top end of the ‘near colorless’ category and gives you a very white sparkle.
There can be a significant cost difference between an H and a G color grade depending on a variety of factors, including the diamond's overall quality, market conditions, and the retailer's pricing policies. Price increases can be dramatic when moving up even one color grade in this carat range, especially in the near-colorless category.
Additionally, the choice of metal for the setting can influence the perceived color of the diamond. Setting a diamond in platinum or white gold, for example, can enhance its color and make it appear even more radiant.


Cut is the most important feature of any diamond, regardless of carat weight. The cut is what transforms a rough diamond into the sparkling gem we hold in such high regard. It should be noted, however, that not all cuts are created equal.
With a 6-carat diamond, any flaws in the cut are magnified, making it imperative to prioritize cut quality when selecting a stone of this size. A badly cut diamond will look dull, flat and lose vibrance or beauty. With the considerable savings that lab diamonds provide, it is no longer necessary for anyone to compromise on the most important C – Cut Quality.
A 6-carat diamond demands a great cut, and overlooking this important feature could result in a glassy, lackluster diamond. The cut should be a priority when you consider your budget as it will have the greatest impact on the beauty of a diamond. It is highly recommended to prioritize the investment toward the cut, which elevates the stone from ordinary to extraordinary.

Collection Quality

For 6 carat diamonds above a very respectable VS2 clarity and a G color grade, much of the appeal is owning a collection quality diamond. But moving into D-F and VVS-FL diamonds will mean a considerable increase in price. For those seeking these elite diamonds of ultimate rarity grades, our A CUT ABOVE® Collection Series was created with you in mind.
Only diamonds which meet the strict cut specifications and carry the top color and clarity grades are part of the Collection Series. Finding 6-carat diamonds that meet all these criteria is extremely rare and are coveted by diamond connoisseurs with means.

The Fifth C – Certification

A GIA report should always accompany a fine large diamond. The leading gem laboratory in the world provides accurate and consistent diamond grading, and diamonds without them may be of questionable quality.
All the hard work has been done for you with our natural and lab-grown diamonds at Whiteflash. For your peace of mind, each diamond is laboratory graded and comes with comprehensive additional evaluations done by the Whiteflash gemological review team.

How Much Does a 6 Carat Diamond Cost?

The price difference between 6-carat diamonds can be huge – tens of thousands, or even hundreds of thousands of dollars separate quality diamonds from subpar diamonds.
The value range for a 6-carat diamond ring is broad, which makes it difficult to give an average, let alone an appropriate target price.
For the lower end of a 6-carat natural diamond budget, we would suggest a minimum of $70,000 – the majority of this budget will be focused upon cut quality, while the color is likely to be somewhere in the I-K range, and the clarity in the SI grade range.
You won't find a 6-carat diamond with a low price that's of high quality; if it's considerably cheaper than the usual price, it's likely to be of poor quality and not worth your time. Always buy from a respected jeweler and make sure you’re as informed as you can be on your purchase.
We are experienced in working to help our customers find the diamond of their dreams regardless of their budget, however a 6-carat natural diamond at a low price will lack the precision and beauty that Whiteflash recommends.
Ask yourself, why a six-carat diamond? If you want a diamond with impact, or a ‘big’ diamond, consider a fancy shape such as oval or pear shape, which will help maximize your carat weight for a given budget. You may even opt for a lab grown diamond instead. Consider halo settings that embellish and enlarge the overall look of the diamond. These considerations will allow you to focus on quality while still getting a "big" diamond look.
A realistic budget today for a natural 6-carat diamond with exceptional light performance and decent color and clarity would be over $100,000.

6 Carat Lab Grown Diamonds

Finding a large diamond at a reasonable budget is easier today than ever before due to the emergence of lab created diamonds. A Lab grown diamond is a real diamond, not an imitation like CZ and Moissanite. They are true synthetic diamonds with essentially the same physical and optical properties as natural diamonds.
Technology to produce them is rapidly evolving and bigger high quality lab diamonds are starting to become more available - which makes finding a 6ct lab grown diamond at a great price with outstanding properties a very real possibility.

6 Carat Lab Diamond Pricing

As mentioned above, lab diamonds are getting better and better, and producers are able to grow bigger diamonds and improve quality at the same time. There are two methods used to create lab diamonds; CVD and HPHT and there are some significant differences between them.
It is possible to compare prices online, but make sure you educate yourself on some of the unique things to be aware of when shopping for a large lab diamond.
6 ct lab diamond cost is highly variable, and while far less expensive than a natural diamond, you will still have to keep the 4cs in mind. This means spending money in the right areas to get a high quality lab grown diamond in this size. Also be aware that there are some quality factors that may not be covered on a laboratory report, such as transparency issues or odd color tinges. This is where choosing your merchant carefully is so important.
The cost savings associated with lab-grown diamonds will ultimately make them an attractive choice for shoppers seeking a stunning 6ct diamond.

Settings are a great way to express your personality or simply let your diamond do the talking. It is important to balance style and durability, and diamonds with bigger carat weights require a particular focus on function. Diamonds that are heavier are subject to different criteria.

Which Setting Is Best for 6 Carat Diamonds?

A prong setting is a classic and secure way to set your diamond. We recommend a minimum of six prongs to hold a 6.00ct diamond. Many designer settings will feature platinum prongs for added durability, to give you peace of mind while wearing your 6-carat diamond.
Solitaire settings typically feature a diamond mounted on a simple band without any additional accent stones or embellishments, allowing the diamond's beauty to take center stage. Diamonds are made prominent by this versatile design, which emphasizes their size, brilliance, and clarity.
A bezel setting is another solid choice. The diamond's extremities are protected, making sure it doesn't catch or scratch. With a bezel setting, you can have a striking and contemporary look and wear it every day with full confidence.
The designer brands we represent are the experts; renowned all over the world for their innovation and craftsmanship, they create settings that are designed to be secure, beautiful and durable.
It is best to avoid tension or suspension settings for six carat diamonds because they are not suitable for diamonds of significant weight. Apart from this, there are a wide variety of styles suited to six carat diamonds, and we can’t wait to help you find your favorite!
