Lab Grown Diamonds

Also known as lab-created or synthetic diamonds, lab grown diamonds are an often misunderstood gemstone. Let's delve into their creation process, understand what sets them apart, and explore why and how their efficient production leads to a significantly lower cost compared to natural diamonds.

What is a Lab Grown Diamond?

Lab grown diamonds are precious gemstones which are made in a laboratory. These gemstones are created using technology which accelerates the growth process of natural diamonds, which form over millions of years. Laboratory grown diamonds not only provide a more environmentally conscious option but they are also generally more affordable than mined diamonds.

Lab Grown Diamonds vs Natural Diamonds

Have you ever wondered if a lab grown diamond is a real diamond? Well the answer is yes! Lab grown diamonds are absolutely real diamonds. The only difference between lab grown diamonds and mined diamonds is their origin, with mined diamonds being formed in the earth over millions of years and lab grown diamonds being created in a laboratory over the course of a few weeks or months. Other than this, these two gemstones share the exact same chemical composition, as well as the same hardness level and visual appearance!

Lab Grown Diamond Value

The price of any gemstone depends on a few different factors including their carat weight (size), colour, clarity and cut. These four elements are known as the 4 Cs and are used universally to determine the price of gemstones, especially diamonds. Learn more about the 4 Cs to get a better understanding of how these factors affect the price of a gemstone. 


Lab grown diamonds can cost anywhere from 60% to 80% less than traditionally mined diamonds, making them a great alternative if you’re looking for something a bit more budget friendly. This is due to the fact that they require less land and resources to be sourced and therefore don’t cost as much to be produced! Read more in our lab grown diamonds price guide to learn all about the cost of lab grown diamonds.

How Lab Diamonds Are Made

Now it's time to get scientific! Lab grown diamonds are made using one of two methods, high pressure or high temperature (HPHT) and chemical vapour deposition (CVD). HPHT diamonds are made using extreme pressure and high temperatures to mimic the natural conditions where diamonds are formed deep within the earth. CVD is a process where a gas is used to place tiny carbon particles onto a surface, slowly forming a diamond layer by layer.


Each of these formation processes all produce the same result, so don’t fret that each of these methods might make a different type of diamond! If you’d like to learn more then read our guide on how lab grown diamonds are made. 

Lab Diamond Hardness

Due to the fact that there’s no physical or chemical difference between lab and mined diamonds, these two stones hold the same exceptional hardness level! Diamonds, whether lab grown or mined, are the strongest naturally occurring substance on earth and score 10 on the Mohs scale of mineral hardness! This makes them perfect for everyday wear as they don’t scratch or crack as easily as softer stones, so it's no wonder they are the number one choice for engagement and wedding rings.


The Mohs scale of mineral hardness is a scale that jewellers, buyers and academics use to measure the scratch resistance of various minerals and gemstones. Each mineral or gemstone is assigned a score from 1 to 10, with 10 being the hardest (diamond). Take a look at our graph below which shows where different gemstones land:

Caring for Your Lab Grown Diamond

Caring for your lab grown diamond ring is easy! All you need is some warm soapy water and a gentle toothbrush (a baby toothbrush does the trick), once you have these all you need to do is give it a gentle scrub, making sure to get into all the crevices. Make sure you always take off your jewellery when handling chemicals, such as cleaning products, nail polish remover and other abrasive products as these can tarnish or damage your ring. We have compiled a guide on how you can best care for your engagement ring if you would like some more tips! We also offer a repair and refresh service if you think your ring might need some professional attention.

Lab Diamond Colours

Just like natural white diamonds, white lab grown diamonds also come in a variety of hues and shades ranging from bright whites to creamier undertones. However, due to their man made nature, lab grown diamonds are less likely to have inclusions and often feature a clearer and more colourless appearance. 


Diamonds are scored on a colour grading system, where they are placed on a scale from D (colourless) to Z (light yellow/brown).

Things to Consider When Selecting a Laboratory Grown Diamond

1. Understand the 4 Cs

Familiarise yourself with the four essential characteristics of diamonds: Cut, Colour, Clarity, and Carat weight. While lab grown diamonds share these characteristics with natural diamonds, each factor contributes to the overall appearance and value of the stone. Our guide on the 4 Cs goes into detail on how these factors affect a diamonds overall quality and cost.


2. Determine Your Budget

Set a clear budget for your engagement ring. Lab-grown diamonds are often more affordable than their natural counterparts, but prices can still vary. Having a budget in mind will help you narrow down your options and find the best value ring for you. Take a look at our guide on how to set a budget for your engagement ring.


3. Consider Diamond Shapes and Styles

Explore various diamond shapes and ring styles to find what resonates with your preferences and fits your lifestyle. Lab grown diamonds are available in a range of shapes, from classic round to modern hexagon cuts. Additionally, think about the setting and design that will best showcase the diamond while aligning with your personal taste. We have a ring anatomy guide so you can learn all about the different elements of a ring.


4. Choose the Right Colour

Lab grown diamonds come in a variety of colours. While most are nearly colourless, some may have a slight tint. Consider your preferences and how the diamond's colour complements the metal of the engagement ring.


5. Environmental and Ethical Factors

Research the environmental and ethical practices of the lab-grown diamond producer. Many people choose lab grown diamonds for their eco-friendly and conflict-free attributes. Ensure that your jeweller follows ethical sourcing. So, are lab grown diamonds more ethical? Read more about how they're made in our 'How Lab Grown Diamonds Are Made Guide'.
