A one-carat diamond will often set you back somewhere between $1,800 and $12,000. The cost of a diamond is determined by its Cut, Clarity, Colour, and Shape. One carat of the diamond can range in price from several hundred to several thousand dollars depending on the quality of its cut.

Even though it was the cheapest one-carat diamond we could find, we wouldn't recommend wearing it as a ring. However, this 1-carat diamond is as flawless as they come. Is twelve grand the smartest way to spend it? We suggest striking a middle ground to get the most out of both.

The diamond's weight, in carats, defines a diamond as a "1-carat" diamond. A carat is the unit of measurement for diamond weight, and one carat is equivalent to 200 milligrammes. A 1-carat diamond is about the same size and weight as a fourth of a raisin. Diamonds are always sold by their carat weight. Suppose a diamond weighs 0.5 carats and sells for $1,400 total. A diamond of this quality would cost $1,400 times 0.50, or $700. Diamonds with a larger carat weight have a higher price per carat.

As the carat weight of a diamond increases, so does the price per carat, leading to a multiplicative increase in overall diamond cost. A 1-carat diamond with similar qualities may cost $4,615 or more per carat, while a 2-carat diamond with similar attributes could cost $7,390 or more per carat.

A diamond slightly below a new weight category, such as a 0.90-0.99 carat diamond, may appear like a good deal at first, but this is rarely the case. In recent years, looking for diamond rings containing "nearly" 1 carat has become increasingly fashionable. As a result of their elevated demand, the price of these diamonds has increased, reducing any potential savings.

It's possible to look for a diamond with a 0.90-carat carat weight, but doing so will narrow your search results without providing any savings. Because diamonds are so emotionally charged, their value is frequently difficult to pin down. The fact that many diamonds on the market are poorly cut is entirely attributable to this peculiarity of "feelings" inside the diamond industry.

The Right Weight For Your Ring

Choosing a gem for a ring is a personal decision that is influenced by several factors. Understanding and prioritising those factors will assist you in selecting the appropriate carat weight. Keep the following suggestions in mind.

Carat Weight And Size

Keep in mind that carats are a measure of weight and not size. A one-carat gemstone can appear substantially bigger or smaller depending on the style of cutting used. According to data from Four Mine, a one-carat diamond with a round cut can measure up to 6.5 mm in diameter, while a princess cut diamond of the same weight measures only 5.5 mm. Also, one-carat diamonds can be found in a range of sizes depending on the jeweller.

Set Your Budget

While there is no hard and fast rule regarding how much you should spend on an engagement ring, knowing your budget will help you make wiser choices once you begin looking at stones. When everything else is the same, the price per carat increases and the ideal size of a diamond ring is the size that doesn't strain your finances.

Consider Finger Size

The circumference of the wearer's finger should also be taken into account because it is an essential factor. A ring with a total weight of two carats or more could look stunning on the future bride if her fingers are exceptionally long. On the other hand, if her hands are little and delicate, a large gem can look out of place on her finger.

Think About Setting

The size of a gem in a ring depends on many factors beyond its carat weight. Adding a halo or side stones can make a gemstone look larger than it is. In addition, the majority of ring settings for engagement rings are created to hold a particular carat weight and diameter of the jewel. Selecting one that is too big or too tiny will cause it to not fit flush on the ring.

Practicality And Preference

While giant gems certainly have their beauty, they aren't always the best option. A smaller stone may be preferable if the wearer works with her hands or otherwise wants to avoid prominent rocks. A smaller stone may appeal to those who value minimalism. These considerations are crucial when selecting the ideal gem size for you.

FAQs About Diamond Ring

The term "carat" stands out as the most significant of these four indicators. The diamond's weight, measured in carats, is indicated by its name. How well it functions depends on how much you paid for the diamond.

The weight of one carat is equal to exactly 200 milligrammes. The diamond's "carat weight" is the value of its apparent mass. The higher the carat weight of a diamond, the higher the price. Even though carat is not a direct measurement of size, it is associated with the size of a diamond and hence a significant factor in determining the price.

The weight of the diamond is expressed in carats. One carat is equivalent to 0.2 grams (or 200 milligrams). Just how much does a 1-carat diamond weigh? About the same as a quarter of a raisin.

How Big Is A 1 Carat Diamond Ring?

The average diameter of a diamond that weighs 1 carat is 6.5 millimetres. In this dimension, a perfectly round diamond would measure. The area of other shapes may vary widely. The table size of an oval, pear, or marquise diamond is greater than that of a princess, or Asscher cut diamond, which is typically just about 5.5 millimetres in diameter.

How Much Does 1 Carat Diamond Cost1

A 1-carat diamond is certainly large enough to command attention, despite appearances to the contrary. Although the diamond's size and carat weight are essential, the diamond's cut quality matters when it comes to the ring. A dull 2-carat engagement ring will be less brilliant and noticeable than a magnificent 1-carat diamond ring that glows brightly like this one from the Blue Nile.

Where To Buy A 1 Carat Diamond Ring

Don't be daunted by how big the diamond trading industry is. You may easily find many trustworthy vendors selling high-quality diamond jewellery online or in local shops.

Finding a reputable online retailer is your best bet when shopping for 1-carat diamond rings since they typically provide a wider variety of high-quality stones than brick-and-mortar establishments. You can have stunning mountings in 18-karat or 14-karat white gold, yellow gold, rose gold, or platinum. There is a better possibility of getting a high-quality diamond at a low price if you shop online.

The Four Cs

Understanding the "Four Cs" of a diamond's cut, colour, clarity, and carat is essential before purchasing an engagement ring. When comparing diamonds, all of these factors are of equal importance, but Tiffany & Co. says that the cut is the most important.


The cut is the only aspect of a diamond that can be affected by human intervention rather than mother nature, making it vulnerable to fraud and abuse. If a diamond is cut poorly, it will lose its signature radiance. The diamond's "fire" is the result of the light reflecting off and leaving the diamond, which is determined by the angles and sizes of the diamond's 57 or 58 facets. The sparkle will be muted if you cut the diamond too deeply or too shallow.

The cut also has a role in the final form of the diamond. The round cut is the most popular, although other shapes like emerald, pear, marquise, princess, oval, and heart are also available. If you want to ensure you're not missing any possibilities, it's a good idea to ask to view all of these forms, even if it's only a photograph.


White, or lack of colour, is the most desirable and scarce of all colours. Colourless diamonds receive a "D" rating in the jewellery industry. Between D and Z (don't ask what happened to A, B, and C), diamonds will show off more nuanced hues of colour. Fancies are incredibly uncommon diamonds that have a clear, unambiguous shade.


The clarity of a diamond is sometimes a source of unnecessary stress for consumers. Most diamonds have minuscule "inclusions," also called "nature's fingerprints," which can be seen under a jeweller's loupe (magnifying eyeglass). They resemble tiny clouds or feathers but are typically undetectable by the human eye. While inclusions can reduce a diamond's brilliance, they also give your stone a one-of-a-kind quality that shouldn't be automatically disregarded as a flaw. Why spend so much time fretting over an invisible problem? If the stone has a grade of SI1 (Slightly Included 1) or higher (the best and most expensive degree is IF, or Internally Flawless; the poorest quality is I3, or Imperfect 3), you should be fine.


A diamond's carat weight indicates its overall size. One carat is equivalent to two hundred milligrammes. One carat is equivalent to one hundred points. For instance, 75 points are equal to 3/4 of a carat. Most diamonds used in engagement rings are between one-and-a-half carat in weight. Carats are not to be confused with karats, the unit of measurement for gold purity.

When exhibiting diamonds, any respectable jeweller will be well-versed in the "four Cs" and ready to explain them at your request. But let's say you're wary about putting your faith in a jeweller. A diamond that has been evaluated, graded, and coded with a laser by a third-party gemological laboratory is called a "cert stone," and it is what you should ask for. Because not all certificates are accepted everywhere, knowing the type is crucial. GIA certifications are the most widely accepted ones in the world (the Gemmological Institute of America). In addition to HRD, IGL, EGL, and AGS, there are a slew of other widely held certifications (see Diamond Certificate Issuers, right). Your diamond's carat weight will determine the price of its grading certificate, but detailed pricing information is available only by contacting a grading lab directly. And don't be shy about getting your certificate instead of relying on the jeweller's advice.

Tips To Help You Find The Perfect Engagement Ring

When should they go engagement ring shopping? Congratulations! While it's tempting to be swept up in the excitement of shopping for an engagement ring and planning a proposal, it's essential to keep in mind that the diamond itself will likely cost a significant sum of money.

Whether you and your future spouse will be shopping for engagement rings together or separately, this comprehensive guide is essential.

Narrow Down What Shape You Want

To narrow your search for an engagement ring, knowing the diamond shape your future spouse prefers is helpful. Everybody (or cut) has a unique price tag, and the cost per carat varies widely. The least expensive shapes are the pear and marquise, with the most costly being the round cut.

If the carat weight is your primary concern, you can save money by going with a non-round cut diamond instead of a round one. Learn about the many types of ring cuts and decide which one (or two) you like most before venturing out to look for an engagement ring.

Choose A Metal For The Band

Yellow gold, white gold, silver, and platinum have all been the traditional metals for engagement rings and wedding bands, respectively, but in recent years rose gold has arisen as a new, modern option. Platinum and silver may look identical, but the latter is far less expensive due to its lower density (and rarer). It would be best if you thought about your lifestyle and your money before deciding how much influence metals are in making your final purchase decision because some metals are more accessible than others.

Have A Carat Size In Mind

Some people would rather have a larger stone than a whiter stone, while others would rather have a diamond that is as clear as possible regardless of its carat weight. "The future spouse ought to have some concept of her (or his) stone size,". While it's true that other factors, such as colour and clarity, can be adjusted to meet your needs and price range, "size is always the kicking-off point."

If the carat size is essential, agree on a target before shopping, and be flexible with the rest to stay within your price range.

Don't close your mind out, though. Even though your partner is confident they know exactly what they want in terms of ring size and shape, they may be surprised to discover that they prefer something completely different after trying on a variety of options. A larger diamond of a less standard carat size will cost much less. Diamond prices skyrocket for the most desirable carat weights, such as half carats and whole carats (.50, 1, 1.5, etc.). “ You can save money by purchasing a diamond slightly under these standard weights, and no one will be the wiser.

Get Measured Correctly

It might sound silly to mention, but you should each have your ring fingers measured. It would be best to avoid a ring that is either too tight and prevents blood from flowing to your fingers or too loose and perhaps losing your finger. It needs to be close but not uncomfortable. Get measured for a ring at a jewellery store on your own time and then drop hints about it the next time the subject comes up (or tell your best friend so they'll know the answer if your spouse asks).

Consider How Your Engagement Ring Will Look with Your Wedding Band

It's easy to get wrapped up in finding the perfect diamond engagement ring, but that's only half the equation (or less than half if you're going the rink stack approach). The other part of the symbolism of your marriage is your wedding band. Wedding bands are an essential accessory, so it's important to give some thought to which one would look best with your ring. It is crucial to think about the whole package of prong versus pavé versus channel-set stones before committing to an engagement ring type because some engagement rings don't enable a band to fit flush against them.

Always Buy Certified

Buying an engagement ring is a significant investment, so you should take your time looking. If you've found the right ring, you probably want to be sure a reliable organisation has independently confirmed the stone inside. The Diamond Expert warns that diamonds graded by unreliable labs may have exaggerated grades in order to make them appear more attractive to potential buyers. Weissman asserts that this is the most typical form of fraud by jewellers.

Make Sure The Certificate Matches The Diamond

Checking the girdle of a diamond with a jeweller's loupe reveals laser engravings on the majority of stones. Many diamonds include inclusions, so you can examine the stone and use the certificate's map to locate its flaws.

Be Smart About The Quality Of The Cut And Clarity

If you're on a tight budget, buying the whitest diamond possible will save you a tonne of money. This is commonly an I or J colour grade for a round diamond set in white gold. It's possible to use a K shade in yellow gold. It's a massive cost jump from a J to a D colour.

The same holds for the pursuit of transparency. Choose the lowest clarity diamond that is still eye-clean, as, all else being equal, it will appear to be similar to a flawless diamond. Compared to a perfect diamond, the price of a diamond with a clarity grade of SI1 or SI2 is much lower.

Yet, the proprietor of Concierge Diamonds, a private jeweller, stresses the importance of never compromising on the diamond's cut. Why? The diamond's cut is responsible for its dazzling brilliance. "Even a mediocre raw diamond may be made to appear spectacular with the right cutting. Instead, if you take a high-quality natural diamond and ruin the cutting, it will seem like a turd.

Negotiate Like A Boss

West's design director and founder claim that the markup on engagement rings can go well beyond what is reasonable. Indeed, some rings have price increases of 500% or more. Do your homework before making a final decision, and don't be afraid to haggle with the jeweller to acquire the greatest quality within your price range that meets your expectations.

Head To The Wholesale District

To cut costs, fine jewellery startup Entendre suggests partnering with atypical diamond dealers or distributors. They are able to engage with consumers on an individual basis because of a wholesaler or a private store." Plus, we can save over 30% and provide the best value because we don't have the exact overhead costs that conventional stores do.
