Lab Grown vs Natural Diamonds: A Comparison Guide From Studio Experts

Published June 1, 2026

If you’re comparing lab grown vs natural diamonds, the simplest answer is this: both are real diamonds, but they don’t cost the same, hold value the same, or carry the same meaning. Lab diamonds usually give you a larger or higher-grade stone for less, while natural diamonds are still chosen for rarity, long-term value, and the feeling of owning something formed naturally over time.

A lab diamond isn’t glass, cubic zirconia, or a fake stone. It has the same basic structure as a natural diamond, and once it’s set in an engagement ring, most people won’t be able to tell the difference by eye.

Still, the difference matters.

In our studio, this question comes up all the time. It usually starts with, “Which one is better?” But the better question is: what do you want the ring to mean, and what are you comfortable paying for?

Once you get past the sparkle, choosing between lab grown vs natural diamonds comes down to origin, rarity, price, long-term value, and feeling.

Key Takeaways

Lab diamonds are real diamonds, but they’re grown in a lab instead of forming underground.
Lab diamond prices have dropped a lot, so resale value is worth thinking about.
Natural diamonds are often chosen for rarity, tradition, and meaning.
The right choice depends on what matters more to you: size, budget, rarity, value, or sentiment.

Are Lab Diamonds Actually Real Diamonds?

Yes. Lab diamonds are real diamonds.

They have the same basic chemical composition and molecular structure as natural diamonds and are graded by cut, colour, clarity, and carat. They are both crystalized carbon and have the same density. So when people compare lab grown diamond rings vs real ones, the wording can be misleading. Lab diamonds are real. The better comparison is lab grown diamonds versus natural diamonds.

The main difference is how they’re formed. A natural diamond forms deep in the earth over a very long time. On the other hand, a lab diamond is grown in a controlled environment using technology that recreates diamond growth.

So, if someone asks, “Are lab diamonds real?” The answer is yes. If they’re asking whether they’re the same in every way that matters, the answer is not quite.

They can look the same, sparkle the same, and sit in the same ring designs. What they don’t carry is the same rarity, natural history, or long-term market behaviour.

What’s the Difference Between Lab and Natural Diamond Quality?

A diamond isn’t automatically better because it’s natural. It also isn’t automatically better because it’s lab grown.

Both can be beautiful. Both can also be underwhelming. What matters is the actual stone.

For example, a poorly cut diamond can look dull, even if it’s large. Meanwhile, a smaller diamond with a great cut can look brighter than a bigger one chosen only for size.

This is a common mistake people make when comparing lab grown vs natural diamonds. They look at the certificate first and forget to look at the stone properly. Specs matter, but they’re not the full story.

If you want a deeper look at that mistake, we’ve written about the one thing people get wrong when looking for a diamond.

So when it comes to lab vs natural diamond quality, a lab diamond can be just as beautiful as a natural diamond. But beauty isn’t the only reason people choose a diamond.

Why Are Lab Diamonds So Much Cheaper?

Lab diamonds are usually cheaper because they’re not naturally rare in the same way as real diamonds.

They are produced in a controlled setting, and supply has grown quickly due to their lower production costs. And as more lab diamonds have entered the market, prices have also dropped. In fact, lab grown diamonds, on average, are 30 to over 70% less in cost. That price gap is one of the main reasons couples consider them.

For the same budget for a natural diamond, a lab diamond may let you choose a larger centre stone, a higher colour grade, or a more detailed setting. That can help if you already have a clear look in mind.

That said, the full ring budget still matters. Other factors like metal, setting style, side stones, design complexity, and craftsmanship all affect the final cost. If you’re planning the full budget, this guide on custom engagement ring costs is worth reading.

So yes, the lower price is a real advantage. But there’s a trade-off. With a lab diamond, you’re often paying for appearance, size, and practicality. With a natural diamond, you’re paying for its rarity and natural origin.

Do Lab Diamonds Hold Their Value?

This is the question people sometimes avoid asking, so let’s be clear.

Lab diamonds generally don’t hold value the same way natural diamonds can.

Over the past few years, lab diamond prices have dropped significantly as supply has increased and production has become more efficient. Someone who bought a lab diamond a few years ago may now find that a similar stone costs much less today.

That doesn’t make a lab diamond a bad choice. It just means you should buy one for the right reason.

Take, for example, a side by side comparison: a mined natural diamond of 1.06 and a lab diamond of 2.25 carats. Both are SI1 in clarity and an I in color, and a price of $7500, which shows how much more size a lab diamond can offer at the same budget. For the same dollar amount, you can get a much larger lab-grown diamond.

So, if you’re choosing lab because you want a beautiful engagement ring, a larger centre stone, or a more flexible budget, that can make sense. But if rarity, resale value, or long-term market perception matters to you, a natural diamond may feel like the safer choice.

One should remember, however, that natural diamonds aren’t a guaranteed investment either. Still, they have a longer-established resale market, and they’re tied to natural scarcity in a way lab diamonds aren’t.

This is probably one of the biggest lab diamond pros and cons points. The pro is that you can often get a bigger, beautiful diamond for less. The con is that the long-term value story is weaker. If you want to dig deeper, we have a full guide on the value of diamonds over time.

Will Anyone Know the Difference by Looking?

Most people won’t know the difference just by looking at the ring.

A lab diamond and a natural diamond with similar cut, colour, clarity, and carat can look almost identical on the hand. Even jewellers usually need proper tools or a grading report to confirm the origin.

So if your biggest worry is whether people will notice, the answer is usually no. Still, origin isn’t pointless.

Some clients care deeply about the story behind the stone. Others care more about the look. Some want the biggest centre stone they can get within budget. Others like knowing their diamond was naturally formed over time.

We’ve seen couples feel great choosing lab-grown ones. We’ve also seen couples choose natural because the meaning mattered more once they saw both options. That’s why choosing between a lab diamond vs natural diamond isn’t just a visual decision. It’s emotional too.

So Which One Should You Choose?

Here’s the honest version.

Choose a lab diamond if your priorities are size, budget, and visual impact.

Choose a natural diamond if your priorities are rarity, tradition, long-term value, and the feeling of owning something naturally formed.

Neither choice limits your design. A bezel set ring or Art Deco engagement ring can work with either stone type.

Neither choice is automatically more romantic or smarter. They just say different things.

A lab diamond can say, “We chose the look we wanted and made a practical decision with our budget.”

A natural diamond can say, “We chose something rare, traditional, and naturally formed.”

In our studio, the clients who feel most comfortable are usually the ones who understand the trade-off before choosing. They’re not just following a trend or trying to please someone else.

That’s the point of comparing lab grown vs natural diamonds properly. It’s not to prove that one is better for everyone. It’s to avoid regret.

Final Thoughts on Lab Grown vs Natural Diamonds

The debate around lab grown vs natural diamonds can get loud, but the decision itself doesn’t have to be.

Lab diamonds are real. They can be beautiful, practical, and budget-friendly. Natural diamonds are also real, with rarity, history, and emotional weight that lab diamonds don’t fully replace.

If you want the biggest look for your budget, lab may be the better fit. If you want rarity and long-term meaning, natural may feel more right. Most people need to see both options side by side before it clicks.
