Lab-Grown Diamond Price Developments

In the past five years, prices for lab-grown diamonds have been decreasing rapidly. Between 2022 and 2023, our lab diamond price tracking has seen the prices of 1-carat lab-created diamonds decrease by an average of $100-150.

The diamond outlet JCK has observed the same trend, in just one year. , even mighty De Beers is under pressure from low lab-grown diamond prices.

Is the falling lab-grown diamond prices a problem?

The decreasing prices of lab-grown diamonds are not a problem for consumers. Currently, the supply is bigger than the demand, and that’s good for shoppers. You can take advantage of the low prices and save or buy a larger diamond. As long as you buy lab-created diamonds to wear and not for investment purposes, the falling prices are a great thing.

Will lab-grown diamond prices continue to fall?

The future lab diamond price trend depends on supply and demand. There are signs of consolidation in the market, which could lead to decreased supply. But it’s unlikely that prices will go up. In our opinion, lab-created diamond prices might stabilize and then, perhaps, decrease more slowly following technological and manufacturing improvements.

Buying any diamond is a big purchase, and knowing how to get the best stone and where to get the best value for your money is important. That’s why we’ve written several guides to help our readers out. We recommend getting started by reading our popular:

So, before we start comparing diamond prices, it’s critical to understand why lab diamond prices vary a lot. So, we’ll start by explaining what a 1-carat lab-grown diamond is and how diamonds are evaluated.

What Is a 1-Carat Lab-Grown Diamond?

1-carat diamonds are one of the most popular sizes for both lab-created and mined diamonds.

However, as you have already learned, lab-grown diamonds are 60-80% cheaper than mined diamonds. But there are more benefits to lab-grown diamonds.

Lab diamonds are more:

  • Ethical and does not come with the potential negative social impact that mining does, such as corruption, exploitation, or the economic export resource curse.
  • Environmentally, lab diamonds are more sustainable. This is especially true if they are created using renewable energy, as more and more lab diamonds are.

How Big is a 1-Carat Diamond?

The size of a 1-carat lab-grown diamond depends first and foremost on the diamond’s shape. That is because carats are not the size but the weight of a diamond. And different diamond shapes will have different surface areas (perceived size). The most popular shape is the round brilliant. Other shapes include emerald, which is typically one of the cheapest—princess, pear, and heart-shaped, which tend to be more expensive.

A round brilliant lab diamond weighing 1 carat is typically around 0.25 in (6.5 mm) in diameter. But even the size of a round brilliant-shaped diamond varies with the actual cut and, particularly, the depth of the diamond. Excellent or ideal cut diamonds are typically around 6.4-6.5mm in diameter.

What Is the Best Jewelry Type for 1-Carat Diamonds?

A 1-carat diamond is a relatively large diamond. The best jewelry for a diamond of that size depends on how much attention you want to draw to your jewelry. If you prefer to be a little inconspicuous, 1 carat is the perfect size for a ring or a necklace, for example, a pendant.

If you want something more eye-catching and bold, a 1-carat diamond set in earrings would make a statement and draw attention to the beautiful diamonds. But you will need two diamonds, so the price will double. If diamond price is not an object, you could even opt for a bracelet or necklace set with several 1-carat diamonds, but, of course, the total price for your diamond jewelry will multiply.

Understanding Diamond Prices

The first thing you must learn about lab-created diamonds is the diamond 4Cs. We have written an easy-to-read Intro to Lab-Grown Diamonds: The Diamond 4Cs that we recommend you read first. But, if you are in a hurry or just want to know how much you need to shell out for a 1-carat lab-created diamond, you can skip ahead.

In short, the diamond 4Cs are a grading framework created by the . The four Cs are:

If you need a quick diamond-buying refresher, remember these three things when shopping for diamonds.

  • You first need to know that diamonds are all about the sparkle—also referred to as brilliance or fire in the diamond industry lingo. The sparkle is what makes diamonds so unique. So, if you take away one thing, let it be this: Go for the best possible diamond cut grade! Do not buy a large brilliant-shaped diamond with poor brilliance. Always maximize brilliance—size comes second. Even when purchasing a non-brilliant diamond shape, you still want to aim for a well-cut diamond.
  • Quality matters more than quantity! A better-quality lab diamond will appear larger. And more importantly, a low-quality diamond will not look like a diamond! So, when determining the quality of a diamond using the 4Cs of diamond quality, first, aim for the best cut possible, then color and clarity grades, and carat weight last.
  • Pick a diamond just below the popular “round” weights if possible. For example, choose a 0.96-carat instead of a lab diamond that’s 1.0-carat. Avoiding round weights can save you a lot of money, and the best thing is that no one can see the difference.

But it’s not only lower prices that make lab-created diamonds better than mined diamonds. They are also better for the environment and have a more positive impact on society. You can learn much more about that in the following articles:

Prices for Sustainable 1-Carat Lab-Grown Diamonds

Lab-grown diamonds are already a more sustainable and ethical choice than mined diamonds. However, not all lab diamonds are produced using sustainable energy or are set in sustainable materials. Expect a 30-40% premium for 100% sustainable diamonds. The average prices for sustainable 1-carat lab-grown diamonds range from $1200 to $2000.

One of the best places to buy sustainable and zero-emission lab-grown diamonds is Brilliant Earth (read our review of Brilliant Earth).

Pandora, too, focuses on sustainability, as you can read in our Pandora Brilliance review. Still, while we approve of their environmental focus, they are not as good as Vrai or particularly Brilliant Earth.
