Any diamond purchase is a significant investment, so it’s critical to understand how to find the best stone and where to get the most bang for your buck. And that is with lab-created diamonds. But how much lower are lab-grown vs. natural diamond prices?

Diamond prices vary greatly depending on the grade of the diamond and where it’s purchased. For example, a 1-carat lab-grown diamond (one of the most popular carats and cuts) can cost as low as $400 or as much as $4000, depending on the diamond’s four Cs and if you buy at one of the best lab diamonds jewelers.

But one thing that is for sure is that lab-grown diamonds cost at least 70-80% less than mined diamonds – even though they are precisely the same. And better for the environment.

In the following, we’ll compare the lab-grown vs. natural diamond prices to see exactly how much you’ll save by choosing the environmentally and socially better diamond.

Read on to find out exactly how much you can save by choosing a lab-grown diamond over a mined diamond.

What are lab-created diamonds?

Let’s first define a lab-created diamond. Diamonds grown in laboratories are identical to those found in mines. The only distinction between mined and lab-grown diamonds is that mined diamonds were formed billions of years ago and must be extracted from the earth using extensive mining operations. In contrast, lab-grown diamonds are produced in high-tech labs, reducing costs and energy consumption.

It’s that simple. Mined diamonds, also sometimes referred to as natural diamonds, and lab-created diamonds are 100% the same, except lab-created diamonds are cheaper to buy and better for the planet.

Can you tell the difference between lab and mined diamonds?

Let’s answer one of the most commonly asked questions regarding lab-grown and mined diamonds.

No, you can’t distinguish between a lab-grown and a mined diamond. Lab-grown diamonds are exactly the same as diamonds mined from the earth. In fact, lab-grown diamonds are physically, chemically, and optically identical to mined diamonds. They have the same hardness, the sparkle is just the same, and they are 100% real diamonds.

Likewise, lab diamonds are graded the same way as ‘natural’ diamonds based on the 4Cs—carat, color, clarity, and cut—carried out by the same renowned laboratories such as IGI and GIA.
