Diamond Price Per Gram: How Much Is A 1-gram Diamond Worth?

Diamond Price Per Gram: How Much Is A 1-gram Diamond Worth?

We think it’s essential to describe the function of cuts and the color and consider the look of the diamond to effectively respond to the issue of What is the Diamond price per gram?

The four C’s, which stand for cut, carat, clarity, and color, are frequently used to influence the diamond price. Diamonds come in a variety of forms that are specially cut to provide not only an attractive appearance but also an ideal luster.

So the answer to this question is pretty straightforward: The price of a 1-carat diamond can range from $1,800 to $12,000. However, a superb diamond is more than just its size.

When establishing a stone’s value, the four c’s of diamond quality – color, cut, clarity, and carat – are always considered.

Let’s learn more about the cost of diamonds and how you can calculate it!

What Are Diamonds And How They Are Made

Firstly, let’s define what diamonds are! Diamond is a rare, carbon-based mineral that occurs naturally.

The most important type of chemical connection, covalent, connects each carbon atom in a diamond to the four carbon atoms around it.

So, the hardest known natural material is diamond. It also claims the best thermal conductivity of any natural material and chemical resistance.

Due to these qualities, it may be used as a cutting tool and for other durable tasks.

Adamantine brilliance, a high index of refraction, and a large dispersion are other distinguishing visual characteristics of a diamond.

Due to its characteristics, diamond is the most popular gemstone in the world and is suitable for use in specialized lenses where performance and durability are crucial.

What about the origin of diamonds, one would ask? Let’s examine it!

On Earth’s surface, diamonds are not a naturally occurring mineral. Instead, they develop 100 miles below the planet’s surface in the Earth’s mantle, where they are exposed to extremely high pressures and temperatures.

So, how are diamonds created? There is a thorough overview of the four potential diamond-finding areas on Earth’s surface.

Deep-source volcanic eruptions brought the vast majority of diamonds found to the Earth’s surface. These eruptions lift pieces of mantle rock out of the mantle and transport them to the Earth’s surface without melting them.

Xenoliths are the name given to these mantle-derived building elements.

Orientation affects the hardness of diamond crystals. This is because the octahedral crystal planes are parallel to the directions of the maximal hardness.

We have clarified what diamonds are so that we can move to the next topic!

What Carat Weight is a 1 Gram Diamond?

The cost of diamonds is complex. Numerous elements decide what their genuine worth is. That is what they frequently tell you, at least. Though it doesn’t have to be so difficult, it is true.

The tools you need to determine how much a diamond should cost and how much a diamond is worth are provided in this article since, as you are probably already aware, the two are not the same.

Let’s discuss some math!

A gram weighs 1000 milligrams, a carat weighs 200 milligrams, a gram weighs five carats, and one carat weighs 0.2 grams. In other words, asking how much a 1-gram diamond is worth is equivalent to asking how much a 5-carat diamond costs!

Well, 5-carat diamonds are pretty uncommon. That means few individuals in the diamond industry have ever seen one!

Let us give you an example: most diamonds you have ever seen weigh less than 1.5 carats. Any diamond specialist will agree with this!

Let’s sum up some things!

The beauty of a diamond determines its value.

The GIA developed a diamond grading system known as the “4 C’s of diamonds” to control the business and establish a benchmark for comparing gems.

Cut, Color, Clarity, and Carat are the acronyms for the 4Cs.

As I indicated above, in reality, it is more complicated than that. As diamond dealers, we consider dozens of aspects.

Still, this grading method does the work by allowing us (and you) to compare comparable gems, which helps to provide reasonable estimations for the diamond’s worth.

Let’s talk more about famous C’s and how they affect diamonds’ cost!

What Variables Affect Diamond Pricing?

Diamonds are scarce; just like an eye’s iris, no two diamonds on earth are ever precisely the same.

Since there are so many variables involved in diamonds, as we’ve already covered, the ultimate cost of a diamond depends on various elements.

Carat, Cut, Color, and Clarity are the factors that we have briefly covered.

Let’s delve a little further:


The most crucial component of each diamond is its cut.

It is primarily responsible for creating the optimum diamond proportion to reflect the majority of the light that passes through it.

Quick Tip: Always check for the optimum cut, then consider other parameters according to your budget (for example, don’t start by saying, “I have $5k and want 1 carat; let’s see what cut/color I can get”).


You start considering colors when your heart is set on the perfect cut! Between the colorless and the yellowish, you’re lost.

This component influences a diamond’s surface cleanliness, whether or not it includes inclusions (flaws), the kind of inclusion, and whether or not the inclusions are visible to the unaided eye.

These three elements significantly influence a diamond’s price and several others, such as polish, symmetry, and certification labs that evaluate the diamond. This explains the wide variation in 1-carat costs.

For a crystal-clear illustration, consider the price difference between a diamond with simply a decent cut, K color, and I1 clarity and one with an outstanding amount, D color, and VVS1 clarity.

What is the Diamond Price Per Gram?

Everyone can agree that buying a diamond could be difficult. Nothing seems to make sense at first glance, especially if you are unfamiliar with the four C rules. We hope that we clear that now!

It’s crucial to realize that the cut alone can significantly increase the diamonds’ worth. For instance, if the diamond specialists use exquisite cuts, the diamond will be more brilliant.

Carats are essential in addition to the cut. Better diamonds have more carats.

Finding the most significant retailer and concentrating on the diamond that would offer you the most value for your money are the key factors to consider when determining a diamond’s pricing.

Let’s examine pricing in light of the available information!

We are starting at $1,749 for a 0.5-carat round-cut diamond and going up to $26,683 for a 2-carat diamond. Princess-Cut Diamonds start at $1,284 for 0.5 carats and cost $20,450 for 2 carats.

On average, you may purchase a 2ct pear-cut diamond for between $7,000 and $40,000. Depending on the size, Ashoka cuts start at $3,000 and may cost up to $21,5000 for 1ct.

The brilliant cut, which has a one-carat weight range of $2,500 to $18,000 and a two-carat weight range of $58,000, is the last.

The adage “the price is proportional to the quality” is easy to accept, especially regarding diamonds.

The four C’s, which are cutting, colors, carats, and clarity, and which we stated numerous times in the essay, are some elements that influence the cost.

We also pointed out that a diamond with no color is of a higher grade than one with color (that is most often yellow and brown).

Diamonds without color are usually more costly than diamonds with color.

Their cut or form has an impact on the diamond’s appraised worth as well. It frequently occurs that diamonds will cost more because they are in demand.

Based on the above-mentioned considerations, we have chosen a price table for you.

Let’s look at it now!


Shape0.5 Ct1 Ct1.20 Ct1.50 Ct2 Ct
Round-Cut Diamond$1.749$7.291$9.237$13.661$26.683
Princess-Cut Diamond$1.284$4.799$6.794$10.570$20.450
Oval Shape Diamond$1.204$5.462$7.431$11.875$23.861
Emerald-Cut Diamond$1.023$4.476$6.221$9.571$23.513
Table 1

In the table above, we have included the approximate prices of diamonds traded based on their carat weight, starting with the most costly.

As you would have guessed, the round cut diamond is the most expensive, but, surprisingly, the two-carat princess cut diamond is the least costly.

Current Diamond Prices

The most valuable diamonds at these prices are those that are:

  • Excellent Cut
  • Excellent Symmetry
  • Very Good / Excellent Polish
  • No Fluorescence

We decided on these features since they are necessary for an accurate price comparison of diamonds and because you might not want to forego them in the current market.

In light of this, it is always possible to lower the price by omitting some of the factors above.

The fluorescence is the most straightforward and least disruptive to the aesthetic but affects the price.

The price will drop by 5–15% by moving to a faint to medium fluorescence, and as a bonus, the diamond hue may seem whiter (a benefit of moving to this fluorescence level).

Also, keep in mind that these are the costs for loose diamonds!

Whether you choose a traditional solitaire or a more costly mount like a double halo, the ring’s price will increase by another $300 to $2,000 (and much more if you get a designer band).

Prices of 1-carat diamonds

As traditional as engagement rings may get, 1-carat diamonds are.

1-carat diamonds are probably the highest you can go, given that the average engagement ring over the past several years has cost just under $6,000 in total.

Table of 1-carat diamond prices:

Table 2

Our pick for the best value in a diamond is the marked cell of a 1-carat diamond that costs $6,000 and has a G color and SI1 clarity.

It offers a decent white diamond hue that complements white and yellow gold and is essentially as excellent as the eye perceives.

Running a more comprehensive search of diamonds weighing 0.90-0.99ct that are still cut very good to outstanding but may include fluorescence would be the most cost-effective substitute for a 1-carat diamond.

You may find a diamond with a very similar appearance with this search for about $4,350! And if you choose a yellow gold setting, you may lower the price to $4,000 for an H color diamond.

Prices of 2- Carat Diamonds

In recent years, with the economic depression and the drop in demand for luxury goods, prices of diamonds declined (at least for a while) – especially in more significant, more expensive diamonds.

As a result, the prices of 2-carat diamonds had decreased dramatically, in some cases 30% (though still very expensive). So there was no surprise that we started feeling a more robust demand for 2-carat diamond rings.

To answer the question of how much a 2-carat diamond costs, check the chart below:

The pricing table above shows total diamond costs, not per carat, to make things simpler!

Table 3

We’ve suggested three alternatives because they are 2-carat diamonds and the price increments are HUGE financially.

Again, the most terrific deal is a 2-carat diamond graded G SI1 for $21,000. However, given the variations, you might want to consider H SI1 or G SI2.

Remember that the SI2 diamond could not be “eye clean” significantly if it weighs 2 carats. Therefore, it is necessary to confirm this.

For a G SI1 diamond that is still on the cheaper side of 2 carats, decrease the weight to 1.80-1.90 carats and allow fluorescence.

Final Thoughts

Although we have provided you with as much information about diamonds, their appearance, their cost, and many other things in this article, we hope we have succeeded in answering the original question: What is the Diamond price per gram?

We single out the most straightforward answer: A 1-carat diamond may cost between $1,800 and $12,000. But a superb diamond is more than simply its size. The four C’s of diamond quality – color, cut, clarity, and carat – are always considered when determining a stone’s worth.

Price and quality are usually inversely correlated, especially in the case of diamonds.

Therefore, if you are selecting a diamond on your own, remember to consider the renowned “four C” guideline to help you make the best choice.

We hope you enjoyed reading the article as much as we did while writing it!
