Because simple diamond pricing doesn’t work this way, 2 carat isn’t the same as 2 x 1 carat diamonds, since a lot goes beyond this, and that’s what we will be covering here.
This post will be covering the mystery of diamonds pricing, we will see how much 1 carat of diamonds cost, and then will see what’s the diamond price per “gram”! Yes that’s might not sound familiar for many of people, but a lot are aware of gram as a weight unit rather than carat.
What’s the Price of a 1 Diamond Carat?
Does the diamond price only count on carat? Of course not, but to which extent other factors have to determine the diamond final price?
Take a look at this search on James Allen, the search limits the options to 1 carat only, and it gives us thousands of options that range between $2000 and $15000.
Yes, a low quality 1 carat diamond costs $2000, while a different 1 carat diamond may cost $15000 if it’s on very high grades in terms of Cut, Clarity, and Color.
If we want to estimate the cost of 2 carat diamond, would it as easy as doubling these two numbers? Unfortunately no!
If you go to see the highest diamond for 2 Carats, you may end up with +$44000 for 2 carats diamond, and as low as $6000 as you see in these two screenshots:
So 2 Carats diamond is not 2 x 1 Carat diamond, it’s almost 3x.
We will see below.
Diamond Price for 2 Carats Diamonds
Everyone wishes it was just multiplying 1 carat diamond price by two, but the truth isn’t anywhere close from this.
While 1 carat is the most common choice among diamonds shoppers, 2 carats is still popular to a lot of people, and their prices are “somehow” reasonable when you know what characteristics you need to get and not exceed them.
If we do a search on James Allen to find a wide price range for 2 carats diamonds, we see that it starts with around 6k for 2 carats (yes it sounds cheap, but never get such a diamond just for the sake of higher carat!).
And it goes up insanely to around 52k for just 2 carats like this diamond which we also can never recommend!
If we want to be reasonable in finding a fair price for a good 2 carats diamond, we can say it goes between 12k to 20k for ideal cut, SI1-VS2, and H color diamond.
What’s the Diamond Price per Gram?
A diamond carat is 200 milligrams, a gram is 1000 milligram, which means that 1 carat equals 0.2 of a gram and a gram equals 5 carats.
Not sure if you want to know the answer after knowing that a gram is 5 carats, but let’s see.
Gram is 5 carats as we just saw, and in order to understand how large is 5 carats diamond, it’s worth to tell you that +90 of diamonds you’ve seen in your life are less than 1.5 carat!
Diamond price doesn’t count only on the weight, cut, color & clarity play huge part of this, so you can easily find 2 carats diamond cheaper than 1 carat! Because simply the characteristics aren’t the same, and we will see shortly how & why is this.
That’s why it can be very hard to exactly tell how much 1 gram of diamond costs, it’s like saying “how much a red car costs” without any more info!
So the price range is very wide, wide enough so you don’t strict your budget to a specific carat, rather, look for a good diamond for whatever budget you have, and don’t count mainly on Carat!
Why the Price Difference in 1 Carat Diamonds?
Diamonds are unique, like eye iris, you can’t find two identical diamonds on earth, a lot of factors sum up the final price of a diamond, even if it shares the same weight “carat” with others, here are the most important factors that make up the final price of a diamond:
1- Cut: Cut is the most important factor in any diamond, it’s mainly responsible make the diamond proportion so ideal so that it reflects most of the light that goes through it, this image tells you the whole story behind the Cut:
Feel free to reader Cut Chart article to know more about this.
2- Color: Once you set for at least a very good cut, the next important thing to check is diamonds color, it determines how colorless (or how yellowish) the diamond is, and it’s scaled (according to GIA standards) from D to Z, with D being the most colorless grade:
In 99% of cases, you will be safe getting an H color diamond.
3- Clarity: This factor determines how clean the surface of a diamond is, if it has inclusions (imperfections) or not, what types of them, visible to naked-eye or not, and also graded as we’ve seen in Diamonds Clarity Chart from I3 to FL. SI1 is eye-clean in most cases:
These 3 factors (along with many others like certification lab who assessed the diamond, polish, symmetry, etc…) play huge role in determining the price of a diamond, that’s why we see the price difference for 1 carat diamond.
A diamond with excellent cut, D color, VVS1 clarity price will be 5 or 6 times of good cut, K color, and an I1 clarity diamond, that’s why!
What’s the Average Price of 1 Carat Diamond?
Okay, the numbers were very vague, and to have a better estimation, we will look at the average price of 1 carat diamond, where we choose the minimum recommended factors as we stated above.
Roughly speaking, 1 carat diamond costs somewhere between $3500 and $6000 (Very good cut, H or G Color, SI1 or VS2 Clarity).
Why 2 Carat Diamond Price Isn’t 2x of 1 Carat Diamond?
Diamonds are rare, and the larger a diamond is, the less available it is.
For example, as the time of writing this, James Allen has +11000 diamond that weight 1 Carat only (not a cent less or more), while for 2 Carats, they have only 600!
See this search on James Allen and change carat as you wish to see availability.

Recommendation & Bottom Line
When you search for your diamond, don’t ever start by carat, actually carat is the LAST thing between the 4Cs that you should consider.
Always start with the cut, don’t ever get below a very good diamond, even if it was a very small diamond, a 0.5 carat very good diamond is better than 1 carat good one!
Next, head to color and spend your money on what matters, H will be enough for you! As for Clarity, get an eye-clean SI1 and you will be fine.
One last thing, we always recommend our readers to shop online for a lot of reasons, and between all online vendors, we’ve found that James Allen is the best to shop from for almost anyone.
