Lab‑Grown vs Natural Diamonds: Differences, Pros & Cons Explained
If you’ve ever caught yourself thinking, “Lab diamonds are just fancy fakes, right?”, you’re not alone. So many women still lump lab‑grown diamonds in with cubic zirconia and cheap knock offs, and honestly… they deserve better PR. This is your no nonsense, girlfriends‑on‑the‑couch guide to lab‑grown vs natural diamonds. What they actually are, how they’re different, and which one makes the most sense for your life (and your wallet).
Think of this as the “tell me like we’re on FaceTime” version, not the dusty jeweller’s textbook. We’ll bust the “not real” myth, talk sparkle, ethics and budgets, and by the end you’ll know whether you’re a lab grown girl, a natural only purist, or happily somewhere in between.
Quick Answer: Are Lab‑Grown Diamonds Real Diamonds?
Short answer for busy people
Yes, lab grown diamonds are real diamonds. They have the same crystallised carbon structure, the same hardness, and the same brilliant sparkle as natural, earth grown diamonds; they’re just grown in a high tech lab instead of deep under the earth.
If a natural diamond is the original vinyl record, a lab grown diamond is the high quality Spotify stream. It’s still the same song, just delivered with new technology.
Or picture it like this: a natural diamond is like a tomato from a sun soaked backyard garden, and a lab grown diamond is the same tomato grown in a high tech greenhouse, same tomato, different postcode.
Lab‑Grown vs Cubic Zirconia and Moissanite
Here’s where it gets messy. When people hear “lab‑grown”, they picture cheap TV‑shopping stones like cubic zirconia, mystery crystals, that ring you bought in your 20s that went cloudy in a year. Cubic zirconia and clear quartz are completely different materials: they can look sparkly at first, but they’re softer, scratch more easily and lose that crisp, sharp sparkle over time.
Moissanite is another story again, a real gemstone, and most moissanite on the market is lab created. Natural moissanite is incredibly rare. It’s super hard and super sparkly, but it has a different chemistry to diamond and a more rainbow‑flashy, almost “disco ball” look. It can be a great diamond alternative, but it isn’t a diamond.
A lab‑grown diamond is not in that “fake” pile at all. It will test as a diamond, it’s graded for cut, colour and clarity like any other diamond, and it’s built for everyday life, because it is a diamond.
Lab‑Grown vs Natural Diamonds: The Key Differences
Quick comparison in real language
Let’s zoom out and look at what actually changes between a lab‑grown diamond and a natural one, and what doesn’t. The part that doesn’t change is the important bit: the look, the hardness and how it behaves when you wear it every day. The parts that do change are the origin story, the price, and how people feel about them.
Origin
-
Natural diamonds form underground over millions to billions of years.
-
Lab‑grown diamonds are created in a high tech lab over a few weeks.
Material
-
Both are crystallised carbon in the same diamond structure.
-
Chemically and physically, they are identical as diamonds.
Sparkle
-
Both can be ridiculously beautiful if they’re well cut.
-
Cut quality matters far more than origin.
Hardness
-
Both score 10 on the Mohs scale, which makes them suitable for everyday wear.
Price
-
Lab‑grown diamonds usually allow you to go bigger, or choose higher colour and clarity, for the same budget compared to natural diamonds.
You’re not choosing between “real” and “fake”. You’re choosing between two different ways a real diamond can come into the world.
Pros and Cons: Lab Grown vs Natural Diamonds
Why You Might Love a Lab Grown Diamond
If you’re a “more sparkle, less stress” kind of woman, lab‑grown is probably your new best friend. For the same budget, you can usually go bigger in carat, better in colour, or cleaner in clarity, sometimes all three, compared with a natural stone at the same price point. That means the gorgeous, bright, chunky diamond you’ve been saving Pinterest photos of suddenly becomes a lot more doable.
Lab grown also suits modern values: you get a diamond with a clear, documented origin and a tech forward story that feels very now. For everyday luxury diamonds you actually wear to school pick‑up, brunch and the office, not just special occasions, lab‑grown makes a lot of sense.
Things to Keep in Mind With Lab‑Grown Diamonds
Lab-grown diamonds are real diamonds.
They’re made of the same crystallised carbon as natural diamonds.
They form in the same diamond structure.
They have the same hardness.
The same sparkle.
The only difference is where they begin.
Like natural diamonds, there are a few practical considerations.
Because lab-grown diamonds can be produced more efficiently, they’re typically more accessible in price. That’s a big part of their appeal.
Natural diamonds have had a longer-established resale market, particularly for rare and exceptional stones. But most people aren’t buying a diamond as a financial strategy.
They buy it to wear.
To celebrate something.
To mark a moment that matters.
You’re choosing the same diamond material.
The same durability.
The same brilliance.
Often in a larger size or higher colour and clarity, without stretching your budget.Lab-grown diamonds reflect modern technology and shifting priorities.
It’s not “real” versus “fake.”
Why Some People Still Choose Natural Diamonds
Even though lab grown diamonds are real diamonds, some people still prefer natural diamonds. Natural diamonds have been the default choice for generations, so for some buyers, that’s simply what feels comfortable. At the same time, many modern buyers are moving in a different direction and are very happy to choose lab‑grown.
They understand that lab‑grown diamonds have the same structure, the same hardness of 10 on the Mohs scale, and the same brilliance as natural diamonds. The difference is origin, not quality.
Some choose lab‑grown diamonds because they prefer to avoid mining. Others choose them because they want better size, colour or clarity within their budget. And increasingly, lab‑grown diamonds aren’t seen as an alternative, they’re simply seen as a smarter way to buy a diamond.
Both are real diamonds.
Quick Questions About Lab-Grown vs Natural Diamonds (FAQ)
Are lab-grown diamonds real or fake?
Lab-grown diamonds are real diamonds. They have the same chemical, physical and optical properties as natural diamonds. The only difference is that lab-grown diamonds are created in a controlled lab environment rather than forming underground over billions of years.
What is the difference between lab-grown and natural diamonds?
The difference between lab grown and natural diamonds is origin. Natural diamonds form deep within the earth. Lab grown diamonds are created using advanced technology that replicates the natural diamond growing process. Chemically, physically and visually, they are the same.
Can you tell the difference between lab grown and natural diamonds?
No, you cannot tell the difference between lab grown and natural diamonds with the naked eye. In comparable quality, they look identical. Even trained jewellers usually need specialist equipment to identify subtle growth patterns or laser inscriptions.
Do lab grown diamonds test as real on a diamond tester?
Yes. Lab grown diamonds test as real diamonds on standard diamond testers because they have the same carbon crystal structure and hardness as natural diamonds.
Are lab-grown diamonds cheaper than natural diamonds?
Yes, lab-grown diamonds are typically more affordable than natural diamonds of the same size and quality. Because they can be produced more efficiently, lab grown diamonds often allow you to choose a larger carat size or higher colour and clarity within the same budget.
Do lab-grown diamonds have resale value?
Yes, lab-grown diamonds can have resale value, but like most retail jewellery, they typically resell for less than the original purchase price. Natural diamonds have a longer-established resale market, especially for rare stones. Most experts recommend buying a diamond to wear and enjoy rather than as a financial investment.
Are lab-grown diamonds as durable as natural diamonds?
Yes. Lab-grown diamonds and natural diamonds both score 10 on the Mohs hardness scale. That makes both suitable for everyday wear in engagement rings, wedding rings and fine jewellery.
Are lab-grown diamonds better for the environment?
Lab-grown diamonds avoid traditional mining, which many buyers prefer. However, environmental impact depends on how and where either type of diamond is produced. Energy sources, supply chains and transparency all play a role. The best choice often comes down to your personal priorities.
Are lab-grown diamonds good for engagement rings?
Yes. Lab-grown diamonds are an excellent choice for engagement rings because they offer the same durability, sparkle and strength as natural diamonds, often at a more accessible price point.
Do lab-grown diamonds last forever?
Yes. Because lab-grown diamonds are real diamonds, they are just as long-lasting as natural diamonds. With proper care, both can last for generations.
