Choosing a diamond today comes with more options than ever. You may have heard that Lab Grown Diamonds vs Natural Diamonds can look remarkably similar, yet their stories begin in very different places. One is formed through natural geological processes deep within the Earth, while the other is created using advanced technology in a controlled environment. So, what actually sets them apart, and does that difference matter when you are choosing a piece of jewellery? Let’s look at how they are made, how they compare on the 4Cs, what you can expect to pay, and what to consider before making your choice.
Natural Diamonds vs Lab Grown Diamonds: The Basic Difference
The simplest way to understand the difference is to look at the origin. Natural diamonds are formed through geological processes inside the Earth over extremely long periods of time. Lab-grown diamonds are produced by technology in controlled environments, primarily using CVD, or Chemical Vapor Deposition, and HPHT, or High Pressure High Temperature methods.
But there is an important point that often gets lost in the comparison: a lab-grown diamond is a diamond, not a diamond imitation.
According to the Gemological Institute of America, laboratory-grown diamonds have essentially the same chemical composition, crystal structure, and optical and physical properties as natural diamonds. The difference, therefore, is primarily about how the diamond was formed and where that formation took place.
Are Lab Grown Diamonds Real Diamonds?
Yes. Lab-grown diamonds are real diamonds. They are different from diamond simulants such as cubic zirconia or moissanite, which can resemble diamonds but have different compositions and properties. GIA states that laboratory-grown diamonds have essentially the same chemical composition and crystal structure as natural diamonds. They can also look the same to the unaided eye.
This distinction is useful when shopping for jewellery because the terms can sometimes be confusing. A natural diamond and a lab-grown diamond have different origins, but that does not make one a diamond and the other an imitation.
How Are Natural and Lab Grown Diamonds Made?
This is where the two stories really diverge.
How Natural Diamonds Form
Natural diamonds form through geological processes deep within the Earth under the high-pressure and high-temperature conditions required for diamond formation. The resulting rough diamonds are eventually recovered and then cut and polished for use in jewellery.
How Lab Grown Diamonds Are Created
Lab-grown diamonds are created in controlled environments using specialised technology.
CVD, or Chemical Vapor Deposition, uses a carbon-containing gas in a controlled environment to grow diamond material layer by layer.
HPHT, or High Pressure High Temperature, uses high pressure and high temperature to create conditions that support diamond growth.
These are the two primary methods used to produce laboratory-grown diamonds.
Proffini specifically explains both CVD and HPHT on its diamond education page and states that it selects lab-grown diamonds produced through these methods.
Lab Grown Diamonds vs Natural Diamonds: Can You See the Difference?
This is one of the questions buyers ask most often. In most cases, you cannot determine a diamond's origin simply by looking at it. Lab-grown and natural diamonds can have essentially the same optical properties, which means their brilliance and appearance can be remarkably similar. GIA notes that differences in growth characteristics can require examination by trained professionals using specialised gemological equipment.
So if you are looking at two well-cut diamonds, one natural and one lab-grown, the visual difference may not be apparent to the unaided eye. That is why proper disclosure and documentation matter when buying a diamond.
How Do the 4Cs Compare?
Whether you are considering a natural diamond or a lab-grown diamond, the 4Cs remain an important way to understand diamond quality: Cut, Colour, Clarity and Carat Weight.
Cut
Cut has a major influence on how a diamond interacts with light. A well-cut diamond can display strong brilliance and sparkle.
Proffini states that its diamonds are expertly cut to maximise light reflection and sparkle.
Colour
Colour describes the degree of colour present in a diamond. The grading scale helps buyers understand how close a diamond is to the colourless end of the range.
Proffini states that it selects E-F colour lab-grown diamonds.
Clarity
Clarity refers to internal and external characteristics within a diamond.
Proffini states that it selects VVS-VS clarity lab-grown diamonds.
Carat Weight
Carat weight refers to the weight of the diamond. It is often associated with size, but carat weight and visual size are not exactly the same thing because proportions and shape also influence how large a stone appears.
The 4Cs of diamond quality give buyers a useful framework for comparing individual diamonds rather than making a decision based only on whether the diamond is natural or laboratory-grown.
Why Are Lab Grown Diamonds Generally Less Expensive?
For many jewellery buyers, this is where the comparison becomes practical. Lab-grown diamonds are generally priced lower than comparable natural diamonds. Their production is not dependent on discovering and extracting naturally occurring diamond deposits, which creates a different supply model.
For a buyer, that can mean more flexibility within a particular budget.
You might choose to explore a larger carat weight, a different colour or clarity grade, or allocate more of your jewellery budget towards the gold and design.
However, price should not be the only consideration. The diamond's 4Cs, certification, jewellery design, gold purity, workmanship and the jeweller's after-sales policies all matter when assessing the overall purchase.
Are Lab Grown Diamonds as Durable as Natural Diamonds?
Both are diamonds, and diamond is rated 10 on the Mohs scale of hardness. That makes diamond highly resistant to scratching, which is one reason it is widely used in jewellery.
But hardness and toughness are not the same thing. GIA points out that a diamond can still fracture or chip if it receives a sufficiently hard impact, particularly in vulnerable areas.
So whether you choose a natural or lab-grown diamond, a secure setting and sensible jewellery care still matter. Proffini also offers lifetime servicing, including polishing and repair, according to its website.
Can a Jeweller Tell If a Diamond Is Lab Grown?
Not simply by looking at it. Because natural and laboratory-grown diamonds can have essentially the same optical and physical properties, determining their origin can require specialised gemological testing. GIA uses laboratory testing to identify whether diamonds are natural or laboratory-grown and provides distinct documentation for laboratory-grown diamonds.
For buyers, this makes certification and clear disclosure particularly important. If you are purchasing a diamond, check the accompanying documentation and make sure the diamond's origin is clearly stated.
Why Does Diamond Certification Matter?
Buying a diamond is easier when you know exactly what you are getting. A recognised grading report or certificate can provide information about the stone's characteristics and help document its origin.
Proffini states that its lab-grown diamonds weighing 1 carat and above are IGI certified, while every jewellery purchase includes an SGL jewellery certificate.
This gives customers documentation to refer to when evaluating their jewellery purchase. It is still worth checking the specific certificate supplied with your jewellery because certification requirements and documentation can vary according to the diamond and laboratory.
What About the Value of Lab Grown vs Natural Diamonds?
This is where it is worth avoiding simple "better investment" claims. Natural and lab-grown diamonds exist within different market conditions, so buyers should not assume that their future resale values will behave in exactly the same way.
If resale or exchange is important to you, look at the jeweller's actual policy rather than relying on general assumptions about diamond value.
Proffini offers a lifetime buyback and exchange policy, subject to its stated terms and conditions. The policy requires documentation such as the original invoice and relevant certificate, and the jewellery is subject to examination for factors including condition, weight and originality.
That makes the jeweller's policy an important part of the purchase decision.
Are Lab Grown Diamonds More Sustainable?
This question needs a little more care than a simple yes or no.
Lab-grown diamonds avoid the mining process used to recover natural diamonds, but their production is still an industrial process that requires energy and resources. The environmental impact can vary depending on how the diamonds are produced and the energy sources involved.
Proffini positions its lab-grown diamonds as a responsible and more conscious jewellery choice.
For consumers, the best approach is to look at the specific sourcing and production information provided by the jeweller rather than assuming that every lab-grown diamond has exactly the same environmental footprint.
Which Is Better: Natural or Lab Grown Diamonds?
There is no universal answer. For some buyers, the geological origin and natural formation of a diamond are an important part of its appeal. For others, a lab-grown diamond offers an opportunity to purchase a real diamond while having more flexibility within a particular budget.
The decision can come down to what you value most.
If natural origin and geological history are central to your choice, a natural diamond may be the better fit. If budget flexibility, design and the option of choosing a laboratory-grown diamond matter more to you, a lab-grown diamond may be worth considering.
The important thing is to make that choice with the facts in front of you.

The Bottom Line
The Lab Grown Diamonds vs Natural Diamonds comparison becomes much easier once you separate the facts from the assumptions. Both are diamonds. Both can offer the brilliance associated with diamond jewellery. Both can be assessed using the 4Cs, and both can be used in jewellery designed for everyday or special occasions.
The biggest difference is their origin. Natural diamonds form through geological processes inside the Earth, while lab-grown diamonds are created through controlled technological processes such as CVD and HPHT. That difference in origin also contributes to differences in pricing and the way the two categories are positioned in the jewellery market.
So, which one should you choose?
There is no answer that applies to everyone. Look at the diamond itself, its certification, the jewellery design, your budget, the origin you prefer and the policies offered by your jeweller.
Once you understand those differences, choosing between a natural and lab-grown diamond becomes less about following a trend and more about choosing what genuinely suits you.
Frequently Asked Questions
1. What is the difference between lab grown diamonds and natural diamonds?
The primary difference is their origin.
