Size Does Matter: Comparing the Size of 1 vs 2 Carat Diamonds

The size difference between a 1 and 2-carat diamond is quite noticeable. A 2-carat diamond typically measures 8.1mm in diameter while a 1-carat diamond is 6.4mm in diameter – approximately 23.5% smaller than its 2-carat counterpart. This could mean the difference between a subtle sparkle or an impressive statement piece – so consider the size of your ring when making a decision.

Here is a chart to visualize the differences between the two.

That said, 2-carat diamonds are much larger. If you have to sacrifice the cut, color, and clarity then in my expert opinion it’s not worth it. Any imperfections

The Ultimate Guide to the 4Cs: Understanding Diamond Quality and Value


When it comes to both aesthetics and cost, the cut of your diamond is paramount. Based on percentages, proportions, and angles, a diamond’s cut can drastically influence its allure.

When it comes to diamond quality, never settle for anything less than the best your budget allows. An ideal cut can bring out a diamond’s full potential; maximizing its fire, brilliance, and sparkle while enhancing its beauty overall. Although slightly pricier, investing in an optimal cut is worth every penny – you’ll be amazed at the amazing results!

If you looking for the best cut quality diamonds, try the A CUT ABOVE diamonds from Whiteflash, I would also consider the Astor Collection by Blue Nile and True Hearts by James Allen.


Of all the Four C’s, color is usually the least concretely definable and most open to personal choice. People tend to be especially accommodating when it comes to shades of their favorite jewel! For me, a well-cut H color diamond still appears colorless.

Here is a useful chart:

I would not recommend going below an H cut if you’re looking for an “icy white” diamond. If you are purchasing an H cut, make sure that it’s of the highest quality cut as it helps mask the hue.

For customers who prefer the cozy sparkle of J and lower-grade diamonds, these gems provide an excellent opportunity to save money while looking beautiful in yellow and rose gold settings. Generally speaking, larger diamonds tend to reveal more flaws – but this truth doesn’t detract from their beauty or value!


If you’re purchasing a 2-carat diamond, then I would recommend a VS2 or above. This grade certifies that the diamond is impeccable and has no visual inclusions. To put your mind at ease make sure you look out for an “eye clean” mention on the diamond listing and only buy diamonds that come with internationally recognized diamond certification.

One-carat diamonds lend themselves to lower clarity grades since the human eye can’t detect an inclusion in a VVS diamond of that size. As well as diamond certification any reputable vendor should provide HD images and video to accompany the diamond so you can make sure. Often the lighting in showrooms can be misleading, so videos/certifications offer another layer of protection.

The 5th C-Certification

As I’ve hinted at above. Do not purchase a diamond without verification from an internationally recognized lab. If you’re purchasing a real diamond make sure they have a GIA or AGS diamond certificate (please note that AGS Labs have been absorbed by the GIA) or an IGI certificate if you’re purchasing lab-grown diamonds.

Breaking the Bank: Exploring the Price Difference Between 1 and 2-Carat Diamonds

The price difference between 1-carat and 2-carat diamonds can vary significantly depending on the quality and characteristics of each diamond. However, it’s not always the case that you’ll double your money for twice the size. Here’s a chart to visualize the differences between the two:

Natural Diamonds Pricing

Size Price Difference Shape
1 Carat $2,000 – $16,000 Round
2 Carat $9,000 – $60,000 Round

As you can see from the chart, purchasing a 2-carat diamond can sometimes cost up to four times what a 1-carat diamond would cost. This is due to the higher quality and rarity of large diamonds. The difference can be even greater when rare characteristics such as color, cut, clarity, and carat size come into play.

So if you’re looking for a larger diamond but are concerned about the expense, try to find a diamond with the best characteristics you can find within your budget. You may need to compromise on the color, clarity, and cut – but don’t miss out on the chance of owning a magnificent stone that you’ll cherish forever. Otherwise, consider a lab-created diamond:

1 Carat $1,000 – $2,000 Round
2 Carat $1,000 – $6,000 Round

If you don’t have the budget then lab-created diamonds offer great value, it also means that you can put the money that you’ve saved into purchasing that dream designer engagement ring.
