Choosing an engagement ring sounds romantic—and it is—but when you actually sit down to decide, things get surprisingly complex.
One of the biggest questions couples in London are asking right now is simple on the surface: lab grown or natural diamond?
But behind that question sits budget, emotion, ethics, long-term value, and personal taste.
Here’s the thing… there isn’t a single “right” answer. But there is a right answer for you.
Let’s break it down in a way that actually helps you decide.
First, What’s the Real Difference?
At a glance, lab grown and natural diamonds look identical. Even experienced eyes can’t tell the difference without specialised tools.
That’s because they are both real diamonds.
A natural diamond forms deep within the Earth over billions of years under extreme pressure and heat. It’s essentially a piece of geological history sitting on your finger.
A lab grown diamond, on the other hand, is created in controlled conditions using advanced technology that replicates that same environment. The result? A diamond with the same chemical, physical, and optical properties.
If you’re curious about the science, you can explore how a diamond forms and how lab processes like Chemical Vapour Deposition work.
But from a practical standpoint…
They sparkle the same.
They wear the same.
They are the same material.
So why does the debate even exist?
The Emotional Side of Natural Diamonds
Let’s be honest—natural diamonds carry a certain weight.
There’s something about knowing your stone formed billions of years ago, long before cities like London even existed. That story matters to a lot of people.
Some buyers walk into a jewellery showroom, try on a ring, and instantly say:
“I want the real, original one.”
And what they mean is… natural.
That emotional pull is hard to quantify. It’s not about logic—it’s about feeling.
For proposals especially, many people still lean toward natural diamonds because they’re seen as timeless, traditional, and symbolic.
If you’re someone who values heritage, rarity, and that deep sense of permanence, a natural diamond might just feel right.
Why Lab Grown Diamonds Are So Popular Right Now
Now let’s talk about what’s really driving the shift.
Price.
Lab grown diamonds typically cost 30–50% less than natural diamonds of similar size and quality. That’s not a small difference.
It means you can:
- Go bigger in carat size
- Choose higher clarity or colour
- Stay within budget without compromising on appearance
Most people don’t realise how much flexibility that gives you.
Imagine you’ve set a budget for an engagement ring. With natural diamonds, you might need to compromise somewhere—size, clarity, or setting.
With lab grown, suddenly those compromises disappear.
And that matters more than you think, especially if you’re also planning a wedding, buying a home, or managing real-world expenses.
A Quick Word on Value and Resale
This is where things get a bit less romantic—but it’s important.
Natural diamonds historically hold value better than lab grown ones. That’s largely due to their rarity and long-standing market demand.
Lab grown diamonds are more like technology in a sense—the production is increasing, and prices have been gradually adjusting.
So if you’re thinking purely from an investment perspective, natural diamonds tend to come out ahead.
But here’s the reality most jewellers won’t say out loud:
Most engagement rings are never resold.
They’re worn, cherished, passed down, or kept for life.
So unless resale value is a key concern for you, it might not need to be the deciding factor.
Ethical Considerations (And What People Actually Care About)
You’ve probably heard that lab grown diamonds are the “ethical” choice.
It’s not quite that simple.
Natural diamonds today are heavily regulated, especially when sourced responsibly. Certifications and frameworks like the Kimberley Process Certification Scheme exist to prevent conflict diamonds from entering the market.
At the same time, lab grown diamonds avoid mining altogether, which appeals to buyers who are environmentally conscious.
So what do most London buyers actually prioritise?
Transparency.
People want to know where their diamond comes from—whether it’s mined or created—and feel confident in that choice.
What About Style and Design?
Here’s where things get fun.
Whether you choose lab grown or natural, the design possibilities are endless.
You’ll find everything from classic solitaire engagement rings to modern halo settings, vintage-inspired designs, and completely bespoke pieces.
If you’re browsing options, take a look at this curated collection of diamond engagement rings.
It’s a good way to get a feel for styles that actually exist beyond Pinterest boards.
And once you start exploring, something interesting happens…
You stop thinking about where the diamond came from and start focusing on how the ring makes you feel.
Real-Life Buying Scenarios
Let’s make this practical.
Scenario 1: The Budget-Conscious Couple
You want something beautiful but also have other priorities—maybe a wedding in London, maybe travel plans.
Lab grown diamonds make a lot of sense here. You get more visual impact without stretching finances.
Scenario 2: The Traditional Proposal
You’ve always imagined proposing with a “classic” diamond ring.
Natural diamonds tend to feel more aligned with that expectation.
Scenario 3: The Design-First Buyer
You care more about the ring style, setting, and overall look.
In this case, either option works. You can choose based on budget and preference without sacrificing design.
Scenario 4: The Ethical Shopper
You want to feel good about your purchase from a sustainability perspective.
Lab grown diamonds often appeal more here, though responsibly sourced natural diamonds are also a strong option.

A quick conversation often clears up more confusion than hours of online research.
So… Which One Is Better?
This is the question everyone wants answered.
And honestly?
“Better” depends on what you value.
If you care about:
- Tradition
- Rarity
- Long-term value
Natural diamonds tend to make more sense.
If you care about:
- Budget flexibility
- Larger or higher-quality stones
- Modern buying preferences
Lab grown diamonds are incredibly appealing.
But here’s the part people don’t always say out loud…
When someone sees your ring, they don’t ask how it was formed.
They notice how it looks.
How it suits you.
How it feels.
A Final Thought (That Might Help You Decide)
Try this.
Instead of starting with the diamond type, start with the moment.
Picture the proposal.
The setting.
The expression on your partner’s face.
Now ask yourself:
What matters more in that moment—where the diamond came from, or how perfect the ring feels?
That answer usually points you in the right direction.
And once you know that, everything else becomes much easier.
FAQs: Lab Grown vs Natural Diamond Engagement Rings
Are lab grown diamonds real diamonds?
Yes, they are. Lab grown diamonds have the same chemical and physical properties as natural diamonds. The only difference is how they are created.
Can you tell the difference between lab grown and natural diamonds?
Not by looking at them. Even jewellers need specialised equipment to identify the origin. To the naked eye, they look identical.
Are lab grown diamonds cheaper?
Yes, typically 30–50% less than natural diamonds of similar size and quality. That price difference is one of the biggest reasons they’ve become so popular.
Do natural diamonds last longer than lab grown diamonds?
No. Both are equally durable and rank the same on hardness. They’re both suitable for everyday wear.
Which diamond is better for an engagement ring?
It depends on your priorities. If you value tradition and rarity, natural diamonds are often preferred. If you want better value for money and flexibility in design, lab grown diamonds are a strong choice.
Do lab grown diamonds lose value?
They can depreciate more than natural diamonds over time. But most engagement rings are not bought for resale, so this may not matter for many buyers.

They avoid mining, which appeals to environmentally conscious buyers. That said, many natural diamonds today are ethically sourced under strict regulations.
