How Much Does a 1 Carat Lab Grown Diamond Cost?

If you’ve been keeping an eye on the jewelry world, you’ve probably noticed something exciting happening: lab grown diamonds are becoming more popular than ever. These stones are shaking up the market because they’re just as beautiful as mined diamonds but come with some big advantages. One of the most common questions people ask is, “How much does a 1 carat lab grown diamond cost?” That’s exactly what we’re here to explore.
In this guide, we’ll break down everything you need to know about these diamonds. We’ll start by explaining what lab grown diamonds are and how they’re made. Then, we’ll dive into the price of a 1 carat stone, why prices vary, and how they compare to natural diamonds. We’ll also cover where to buy them, tips for saving money, and more. By the end, you’ll have all the information you need to make a smart decision when shopping for a lab grown diamond.
What Are Lab Grown Diamonds?
Let’s get one thing straight: lab grown diamonds are not fake diamonds. They’re real diamonds in every sense of the word. The only difference is that they’re created in a lab instead of being dug out of the ground. There are two main ways to grow these diamonds. One method is called Chemical Vapor Deposition (CVD), which involves using a gas-rich environment to build the diamond layer by layer. The other method is High Pressure, High Temperature (HPHT), which mimics the conditions deep inside the Earth where natural diamonds form.
These diamonds are chemically and physically identical to mined diamonds. If you put a lab grown diamond next to a natural one, even experts wouldn’t be able to tell the difference without specialized equipment. But there are some standout benefits to choosing lab grown. For starters, they’re often seen as a more ethical choice.
Mined diamonds sometimes come with concerns about unethical labor practices, but lab grown diamonds sidestep those issues entirely. Plus, growing diamonds in a lab has a much smaller environmental footprint compared to mining. So, if you care about sustainability or want to avoid supporting harmful practices, lab grown diamonds might be the perfect option for you.
Average Cost of a 1 Carat Lab Grown Diamond
Now, let’s talk about numbers, which are very important here. If you’re looking at a 1 carat lab grown diamond, you can expect to pay anywhere from 800 to 1,800. This is a wide range, and we’ll get into why prices vary so much in the next section. But for now, just know that the cost depends on a few key factors like quality, certification, and where you buy it.
To put things in perspective, a 1 carat natural diamond costs between 4,000 and 7,000 or even more. That’s a huge difference. For many buyers, the lower price tag of lab grown diamonds makes them an attractive alternative. You can get a high-quality diamond for a fraction of the cost, leaving more room in your budget for other things like a stunning setting or even a vacation.
But here’s the catch: while lab grown diamonds are cheaper upfront, their resale value isn’t as strong as natural diamonds. That said, most people buy diamonds to wear and enjoy, not to sell later. So, if you’re focused on getting the best bang for your buck right now, lab grown diamonds are hard to beat.
What Factors Affect the Price of a 1 Carat Lab Grown Diamond?
When it comes to pricing, there’s a lot more to consider than just the carat weight. Here are the main factors that influence how much a 1 carat lab grown diamond will cost:
Cut
The cut of a diamond is all about how well it reflects light. A diamond with an ideal cut will sparkle brilliantly, while a poorly cut one might look dull. An ideal cut will cost more, but it’s worth it if you want a stone that shines. On the other hand, a good or fair cut might save you some money, but the trade-off is less brilliance.
Color
Diamonds come in a range of colors, from completely colorless to slightly tinted. The scale goes from D (completely colorless) to J (near colorless). A D-grade diamond is going to cost more because it’s rarer and looks whiter. But here’s the thing: most people can’t tell the difference between a D and an F or G unless they’re comparing them side by side. So, opting for a near colorless diamond can save you money without sacrificing much in terms of appearance.
Clarity
Clarity refers to how many tiny imperfections, called inclusions, are inside the diamond. A VVS1 diamond has almost no inclusions and costs more, while an SI2 diamond has more noticeable flaws but is still eye-clean in most cases. Unless you’re planning to inspect your diamond under a microscope, you might not even notice the difference. Choosing a slightly included diamond can help you stay within budget.
Certification
Certification is important because it tells you that the diamond has been graded by a trusted organization. The Gemological Institute of America (GIA) and the International Gemological Institute (IGI) are two of the most respected names in the business. Diamonds with certifications from these groups tend to cost more, but they give you peace of mind about the quality of your purchase. Uncertified diamonds might be cheaper, but you’re taking a bigger risk.
Brand & Retailer Markups
Where you buy your diamond matters, too. Some brands charge a premium because of their reputation or marketing. Shopping around and comparing prices can help you avoid paying too much.
Lab Grown Diamond Vs. Natural Diamond Cost
Let’s do a quick side-by-side comparison of 1 carat lab grown and natural diamonds. As we mentioned earlier, a natural diamond costs 4,000 to 7,000 or more, while a lab grown diamond is 800 to 1,800. That’s a savings of thousands of dollars.
But cost isn’t the only thing to think about. Natural diamonds have been around forever, and they hold their value better over time. If you’re thinking about reselling your diamond someday, a natural stone might be a better investment. However, if you’re buying a diamond to wear and enjoy, a lab grown one is just as beautiful and doesn’t come with the same ethical or environmental concerns.
Aesthetically, there’s no difference between the two. Both types of diamonds sparkle, shine, and make a statement. The choice ultimately comes down to your priorities, whether that’s saving money, supporting ethical practices, or considering long-term value.
To help you understand these differences, we’ve put together a detailed comparison table that breaks down the costs and key specifications for 1 carat diamonds.

Certification | GIA, IGI, or uncertified | GIA, AGS, or uncertified |
Resale Value | Lower resale value | Higher resale value |

Where to Buy a 1 Carat Lab Grown Diamond?
Finding a trustworthy place to buy a lab grown diamond is crucial. Reputable online retailers like CaratBee are great options because they offer a wide selection and competitive prices. CaratBee also provides detailed photos and videos of their diamonds, so you can see exactly what you’re getting before you buy.
When shopping online, keep an eye out for return policies and warranties. It’s also good to read customer reviews to ensure you’re dealing with a reputable seller. Certifications are another big deal. Always check that the diamond comes with a report from a trusted grading lab.
Buying locally has its perks, too. You can see the diamond in person and get advice from a jeweler. However, local stores might have higher prices due to overhead costs. If you’re on a tight budget, shopping online is the way to go.

Tips to Save Money on a 1 Carat Lab Grown Diamond
If you’re trying to stretch your budget, here are some practical tips to help you save:
Consider Near Colorless or Slightly Included Stones
As we talked about earlier, you don’t always need a flawless or colorless diamond. Going for a near-colorless or slightly included stone can save you a significant amount of money without compromising on beauty.
Keep in mind that small differences in clarity and color aren’t noticeable to the naked eye. Most people won’t be able to tell the difference between a D and an F or between a VVS1 and an SI1 unless they’re looking very closely.
Choose a Slightly Smaller Carat Weight
Here’s a secret: a 0.90 carat diamond looks almost identical to a 1 carat diamond but costs much less. Jewelers often round up weights, so you can get a stone that appears just as large for a lower price.
Shop During Promotional Events or Clearance Sales
Timing your purchase can make a big difference. Many retailers offer discounts during holiday sales or special promotions. Keep an eye out for deals, especially around Valentine’s Day, Black Friday, or the end of the year.
Conclusion
Lab grown diamonds are changing the game for anyone looking to buy a beautiful, high-quality diamond without breaking the bank. A 1 carat lab grown diamond can cost anywhere from 800 to 1,800, depending on factors like cut, color, clarity, and certification. Compared to natural diamonds, which often cost several thousand dollars more, lab grown options offer incredible value.
They’re also a great choice if you care about ethical and environmental issues. With advancements in technology, these diamonds are just as stunning as their mined counterparts but come with fewer concerns about how they were sourced.
Whether you’re shopping online or locally, there are plenty of ways to find the perfect diamond for your needs. By understanding what affects the price and knowing how to shop smart, you can make a purchase you’ll feel good about for years to come.
