Yes, you can still buy a natural diamond, but whether you should still buy natural diamonds depends on what matters most to you. Natural diamonds offer geological rarity, traditional appeal and a long established place in the jewellery market. Lab grown diamonds, meanwhile, can provide the same diamond material and visual characteristics at a significantly different price point.
For buyers comparing the two today, the most important question is not simply whether natural diamonds are good. It is whether their additional cost represents enough value for your particular priorities.
We recommend comparing certified diamonds on their actual specifications, rather than assuming that a natural diamond is automatically the better purchase. Carat, cut, colour, clarity, certification and overall appearance all deserve careful consideration.

Natural Diamonds vs Lab Grown Diamonds
The biggest difference is origin.
A natural diamond forms beneath the Earth's surface over geological timescales through natural processes. A lab grown diamond is produced using controlled technology that recreates the conditions required for diamond growth.
Importantly, a lab grown diamond is not simply a diamond imitation. It is diamond material with essentially the same chemical composition and crystal structure as a natural diamond. The origin is what distinguishes the two.
This distinction has significant consequences for pricing.
A natural diamond's price can reflect its geological rarity, supply characteristics, market positioning and demand. Lab grown diamonds can generally be produced in greater quantities, which has contributed to much lower prices in many parts of the market.
For someone primarily interested in appearance, specifications and getting the most diamond for their budget, this difference can be substantial.
Why Do People Still Choose Natural Diamonds?
There are legitimate reasons to prefer a natural diamond.
Geological rarity
Some buyers place genuine value on the fact that their diamond formed naturally underground over an extremely long period of time. For them, the geological story is part of the emotional value of the stone.
Traditional symbolism
Natural diamonds have been associated with engagement rings, anniversaries and major milestones for generations. Some customers simply prefer the traditional choice.
Personal preference
Jewellery is personal. If owning a naturally formed gemstone matters to you, that preference has value even if another option offers better specifications for less money.
Established market
Natural diamonds have a long established international jewellery market. However, buyers should be careful not to confuse an established market with a guaranteed investment return.
A diamond is primarily a luxury purchase. Its resale price can depend on many factors, including market conditions, the original purchase price, diamond characteristics and where it is sold.
Why Are Lab Grown Diamonds Becoming So Popular?
The main attraction is often value.
Suppose two certified diamonds have broadly comparable carat weight, cut quality, colour and clarity, but one is natural and the other is lab grown. The lab grown option may cost considerably less.
That creates an important choice.
You could spend the same budget on a smaller natural diamond, or potentially choose a larger or higher specification lab grown diamond.
For example, someone with a fixed engagement ring budget might compare:
| Priority | Natural Diamond | Lab Grown Diamond |
|---|---|---|
| Origin | Naturally formed | Laboratory grown |
| Material | Diamond | Diamond |
| Visual appearance | Diamond appearance | Diamond appearance |
| Geological rarity | Yes | No |
| Typical price position | Higher | Lower |
| Size potential for a fixed budget | Often lower | Often higher |
| Traditional appeal | Very strong | Increasingly popular |
| Certification | Available | Available |
This is why comparing prices rather than focusing exclusively on origin can be useful.
Should You Still Buy Natural Diamonds If Lab Grown Diamonds Are Cheaper?
You can, but you should understand what you are paying extra for.
If your main priority is owning a naturally formed diamond, paying more may make perfect sense. If your priority is maximising size, specification and visual impact within a fixed budget, a lab grown diamond may deserve serious consideration.
There is no universal answer.
Consider a buyer with a £3,000 budget. If they strongly value natural geological origin, they may prefer allocating the budget toward a natural stone.
Another buyer with the same budget might prefer a larger lab grown diamond with excellent cut, colour and clarity.
Neither decision is automatically wrong.
The mistake is assuming that a higher price necessarily means a more beautiful diamond.
Does a Natural Diamond Look Better?
Not necessarily.
When comparing well selected diamonds, visual appearance depends heavily on cut quality, proportions, symmetry, polish, colour and clarity characteristics.
A poorly cut natural diamond can look less impressive than a well cut lab grown diamond.
This is why we recommend assessing the individual stone rather than judging it solely by its origin.
For many buyers, the most noticeable factor is how effectively the diamond handles light. A beautifully cut stone can have impressive brightness and sparkle regardless of whether it was formed naturally or grown in a laboratory.

Certification Matters More Than Many Buyers Realise
Whether you choose a natural or lab grown diamond, certification should be an important part of the buying process.
An independent grading report can provide information about characteristics such as:
- Carat weight
- Colour grade
- Clarity grade
- Cut grade where applicable
- Measurements
- Proportions
- Fluorescence
- Identification of the diamond's origin
Certification helps you compare diamonds using documented specifications rather than relying entirely on marketing descriptions.
However, certification should not replace your own evaluation. Two diamonds with similar grades can still look different because of their proportions, inclusions, light performance and overall cut quality.
Cut Should Be a Major Buying Priority
When deciding whether you should still buy natural diamonds, do not overlook the importance of cut.
A diamond's cut influences how efficiently it reflects and returns light. This can have a major effect on sparkle and overall appearance.
If you are comparing a natural and lab grown diamond, start by examining cut quality and visual performance rather than assuming the natural diamond will automatically look superior.
For round diamonds in particular, proportions and optical performance can be especially important.
A slightly different combination of colour and clarity may also provide better value without producing a noticeable difference to the unaided eye.
Do You Need the Highest Colour and Clarity Grades?
Usually, no.
Many buyers initially assume they need the highest possible colour and clarity grade. In practice, this can result in spending money on characteristics that are difficult to see without magnification.
The right specification depends on the diamond's shape, size and individual characteristics.
For example, a well selected VS clarity diamond can provide an attractive balance between appearance and price. Similarly, moving from one colour grade to another may have a relatively subtle visual impact depending on the setting and diamond shape.
This is where comparing certified lab diamonds can become particularly useful.
Rather than paying automatically for the highest specification available, we suggest identifying the point where additional spending produces a meaningful visual improvement.
What About Resale Value?
Resale is one of the areas where buyers should be realistic.
Neither natural nor lab grown diamonds should automatically be treated as conventional investments.
Retail pricing and resale pricing can be very different. A diamond purchased from a retailer may later be sold through a different channel, where the buyer faces different margins, demand and valuation criteria.
Natural diamonds have a more established resale market, but that does not mean every natural diamond will retain its original retail price.
Lab grown diamonds can face additional price pressure because manufacturing technology allows new supply to enter the market.
If future resale is one of your most important considerations, investigate the likely resale market before buying rather than relying on general claims about diamonds retaining value.
When Does Buying a Natural Diamond Make Sense?
A natural diamond can be the right choice when:
You value natural geological origin
If the fact that your diamond formed naturally is personally meaningful, that can justify choosing one.
Tradition matters to you
Some people want a conventional natural diamond engagement ring because it aligns with their personal expectations and family traditions.
Your budget comfortably accommodates it
If paying the natural diamond premium does not compromise the size or quality you want, there may be little reason to choose differently.
You have a strong personal preference
Ultimately, jewellery does not have to be an optimisation exercise. If you simply prefer natural diamonds, your preference matters.
When Should You Consider a Lab Grown Diamond?
A lab grown diamond may make more sense when:
- You want the largest diamond possible within a particular budget.
- You prioritise cut, colour and clarity over geological origin.
- You want to allocate more of your budget to the setting or other parts of the ring.
- You prefer comparing several specifications before committing.
- You want a diamond rather than a diamond simulant but do not consider natural origin essential.
For many modern buyers, this combination makes lab grown diamonds worth investigating before making a final decision.
How to Compare Natural and Lab Grown Diamonds Properly
Instead of asking only, "Should I still buy natural diamonds?", ask a series of more useful questions.
1. What is my budget?
Set your maximum comfortable spending level first.
2. What size do I want?
Carat weight should be considered alongside the diamond's dimensions and proportions. Two diamonds with the same carat weight can have different visual presence.
3. How important is natural origin?
If the answer is extremely important, a natural diamond may be the obvious choice. If the answer is "not particularly", lab grown diamonds deserve closer comparison.
4. What cut quality am I comfortable with?
Do not sacrifice cut simply to increase carat weight.
5. Which colour and clarity grades offer the best visual value?
Look for a sensible balance rather than automatically choosing the highest grades.
6. Is the diamond independently certified?
A report gives you a stronger foundation for comparing stones.
7. Can I compare the actual diamond?
Images, videos and detailed grading information can help you assess individual stones instead of buying based solely on a generic specification.
Should You Choose Natural or Lab Grown for an Engagement Ring?
For an engagement ring, the decision often comes down to personal priorities.
If the symbolism of a naturally formed diamond is central to the meaning of the ring, choose natural.
If you want to maximise diamond size and specification while keeping your overall spend under control, compare lab grown diamonds carefully.
There is also a middle ground. You can choose a lab grown centre diamond and invest more of the budget into the ring's design, metal, craftsmanship or setting.
The best choice is the one that matches what you and your partner actually value.
A Better Way to Think About Diamond Value
The word "value" does not mean the lowest price.
A £500 diamond is not necessarily better value than a £1,000 diamond. Likewise, a natural diamond is not automatically better value simply because it costs more.
Value is the relationship between what you receive and what you pay.
For one customer, natural origin may be worth paying a premium for. For another, an additional carat of lab grown diamond may provide more satisfaction.
That is why we recommend comparing the complete specification and price together.
Should You Still Buy Natural Diamonds in 2026?
Yes, natural diamonds remain a valid choice in 2026. But buyers no longer need to treat natural diamonds as the default option without considering alternatives.
The growth of lab grown diamonds has made comparison more important. Customers can now evaluate natural and lab grown stones according to origin, certification, cut, appearance, specifications and price.
If natural origin is important to you, a natural diamond can still be an excellent choice.
If your priority is getting strong specifications and attractive visual impact for your budget, it makes sense to compare prices and examine certified lab grown diamonds before deciding.
The key is not to ask which type is universally better. Ask which type delivers the qualities you actually care about at a price you are comfortable paying.
Final Buying Advice
We would not recommend choosing a natural diamond simply because it is traditionally considered the premium option. Equally, we would not recommend choosing a lab grown diamond solely because it is cheaper.
Instead, compare certified stones on their individual merits. Consider origin, cut, colour, clarity, carat, certification, appearance and price together.
If natural formation carries genuine personal meaning, the premium may be worthwhile. If your priority is getting the strongest combination of size, quality and appearance for your budget, lab grown diamonds deserve a serious comparison.
Ultimately, the right diamond is not necessarily the most expensive one. It is the one whose qualities and price make sense for you.
