Discover how lab grown diamonds are created, their benefits, sustainability considerations and how they compare with natural diamonds. Expert guidance from Share Jewellers in Roundhay, Leeds.
Lab grown diamonds have become an increasingly popular choice for customers looking for beautiful diamond jewellery with impressive visual impact and greater flexibility over their budget.
They tell a very different story from natural diamonds. While natural diamonds are formed deep within the Earth over an immense period of time, lab grown diamonds are created using advanced technology and carefully controlled manufacturing processes.
For many buyers, lab grown diamonds combine modern innovation with the beauty and brilliance traditionally associated with fine diamond jewellery. They are now widely used in engagement rings, wedding jewellery, earrings, pendants, bracelets and statement pieces.
At Share Jewellers in Roundhay, Leeds, we believe customers should be given clear, balanced information before choosing between a natural and lab grown diamond. There is no single option that is right for everyone. The best choice will depend on your budget, personal values, preferred design and the story you want your jewellery to represent.
What Are Lab Grown Diamonds?
Lab grown diamonds, also known as laboratory grown diamonds, are created in specialised facilities using technology that recreates the conditions needed for diamond crystal growth.
They are made from carbon and have the same fundamental crystal structure as natural diamonds. They also share many of the same physical, chemical and optical properties, including hardness, brilliance, fire and sparkle.
A high-quality lab grown diamond can look remarkably similar to a natural diamond when viewed with the unaided eye. Specialist gemmological testing and professional equipment are often required to identify whether a diamond has formed naturally or has been produced in a laboratory.
This is why accurate descriptions, independent certification and clear disclosure are essential when buying any lab grown diamond in the UK.
How Are Lab Grown Diamonds Made? 
There are two principal methods used to create lab grown diamonds: High Pressure High Temperature and Chemical Vapour Deposition.
High Pressure High Temperature, usually shortened to HPHT, uses intense heat and pressure to recreate conditions similar to those in which natural diamonds form beneath the Earth’s surface.
Chemical Vapour Deposition, commonly known as CVD, involves placing a small diamond seed inside a controlled chamber. A carbon-rich gas is introduced, allowing layers of carbon to gradually form around the seed and create a larger diamond crystal.
Both processes can produce diamonds suitable for fine jewellery. Once grown, the rough diamond is cut and polished in much the same way as a natural diamond.
Lab grown diamonds are available in many popular shapes, including round brilliant, oval, emerald, pear, cushion, princess and marquise cuts. They can also be graded for carat weight, colour, clarity and cut.
Why Are Lab Grown Diamonds Popular in the UK?
One of the main attractions of lab grown diamonds is their accessibility.
lab grown diamonds are generally available at a lower initial price than natural diamonds with comparable specifications. This may allow a customer to choose a larger stone, a higher colour or clarity grade, or a more detailed jewellery design while remaining within their preferred budget.
For example, someone searching for a lab grown diamond engagement ring may be able to select a larger centre stone or add diamond-set shoulders, a halo or a matching wedding ring without significantly increasing the overall cost.
This flexibility has helped lab grown diamonds appeal to customers throughout Leeds, Yorkshire and the wider UK.
They can be particularly attractive for people who place visual impact at the top of their priorities. They are also increasingly chosen for fashionable jewellery, anniversary gifts, statement rings and pieces featuring multiple diamonds.
Lab Grown Diamond Engagement Rings
Lab grown diamond engagement rings offer a wide range of design possibilities.
A classic solitaire can showcase the size and brilliance of a single diamond, while halo, three-stone and diamond-set shoulder designs can create an even more striking appearance.
Because lab grown diamonds may offer more size for a given budget, customers can explore shapes or settings that may otherwise have been outside their original price range.
However, size should not be the only consideration. The quality of the cut has a major effect on how a diamond reflects light. A well-cut diamond may appear brighter and more attractive than a larger stone with less appealing proportions.
When choosing a lab grown diamond engagement ring in Leeds or elsewhere in the UK, it is important to consider the complete design. The diamond shape, setting style, precious metal and proportions of the ring should all work together.
Natural Diamonds vs Laboratory-Grown Diamonds
The difference between natural and lab grown diamonds is primarily their origin.
Natural diamonds are formed within the Earth through geological processes. Their natural creation, age and finite supply contribute to their rarity and emotional appeal.
Lab grown diamonds are created through modern technological processes in controlled environments. Their attraction often lies in their accessibility, consistent availability and the opportunity to choose a larger or higher-specification diamond for a particular budget.
Both types can offer impressive beauty and brilliance. However, they should never be presented as identical purchasing propositions.
The prices and resale markets for natural and lab grown diamonds can behave differently. Customers should therefore think carefully about their expectations, particularly when considering long-term value, rarity and future resale.
For some people, the natural origin and geological history of a diamond are central to its meaning. For others, visual appearance, size and initial affordability are more important.
A trusted jeweller should explain these differences clearly without pressuring the customer towards either option.
Are Lab Grown Diamonds More Sustainable?
Customers often ask whether lab grown diamonds are sustainable or more environmentally friendly than natural diamonds.
The answer is not as straightforward as some marketing claims may suggest.
A lab grown diamond should not automatically be described as environmentally friendly simply because it has not been mined. Diamond-growing facilities require specialist equipment and significant amounts of electricity.
The environmental impact of a lab grown diamond can vary depending on the production method, the efficiency of the facility and the source of the energy used.
A facility powered by renewable electricity may have a different environmental profile from one that relies heavily on fossil fuels. Transportation, cutting, polishing, jewellery manufacture and packaging should also be considered when assessing the wider supply chain.
Natural diamond production also has environmental and social considerations, which can vary between individual mines, countries, companies and supply chains.
As a result, it is misleading to suggest that every lab grown diamond is automatically sustainable or that every natural diamond has the same environmental impact.
Customers who are concerned about sustainability should ask for clear information about origin, production and certification rather than relying solely on general advertising claims.
Are Lab Grown Diamonds Certified?
Many lab grown diamonds are supplied with an independent grading report.
Depending on the size of the diamond and the grading laboratory, the report may include details about its carat weight, measurements, colour, clarity and cut quality. It should also clearly state that the diamond is lab grown.
Certification can help customers compare diamonds, but it is only one part of the buying process.
Two diamonds with similar grading reports may still look different when viewed in person. Proportions, symmetry, polish and the way each diamond handles light can all influence its overall appearance.
The highest grade on paper does not always represent the most beautiful or best-value choice for an individual customer. Seeing the diamond and comparing different options with the guidance of an experienced jeweller can be extremely helpful.
Do Lab Grown Diamonds Look Different?
A well-cut lab grown diamond can display excellent brightness, fire and sparkle.
To someone viewing the finished jewellery without specialist equipment, the difference between a lab grown and natural diamond may not be immediately visible.
As with natural diamonds, lab grown diamonds are available in different colour and clarity grades. Some may contain internal features or display subtle characteristics caused by the growth process.
The overall beauty of the diamond will depend on a combination of factors, including its cut, shape, proportions, colour, clarity and setting.
This is why it is important to assess the complete appearance of the diamond rather than focusing on one grade alone.
How to Choose a Lab Grown Diamond
Begin by deciding what matters most to you. This may be diamond size, brilliance, colour, clarity, design or overall budget.
It is then helpful to compare several diamonds rather than selecting one purely from its grading report. A slightly lower colour or clarity grade may offer excellent value while still appearing bright and attractive when set into jewellery.
The choice of precious metal can also influence how a diamond looks. Platinum and white gold can create a clean, contemporary finish, while yellow or rose gold may provide a warmer contrast.
For engagement rings, lifestyle should also be considered. A high or intricate setting may offer dramatic visual impact, while a lower setting may be more practical for someone who works regularly with their hands.
Finding Lab Grown Diamonds in Leeds
Customers looking for lab grown diamonds in Leeds should choose a jeweller who provides honest information, accurate descriptions and clearly documented diamond specifications.
At Share Jewellers in Roundhay, we help customers compare natural and lab grown diamonds in a relaxed and informed way. We can discuss the differences in origin, price, appearance and certification while helping you explore suitable designs.
Whether you are searching for a lab grown diamond engagement ring, a special anniversary gift or a bespoke piece of jewellery, the process should be personal rather than pressured.
Viewing diamonds in a showroom also allows you to compare shapes, sizes and settings under different lighting conditions before making your decision.
Choosing the Diamond That Is Right for You
There is no universal answer when choosing between a natural and lab grown diamond.
Some customers value the rarity, natural formation and history of an Earth-mined diamond. For them, its geological journey forms an important part of its romance and symbolism.
Others are attracted to the innovation, accessibility and design possibilities offered by lab grown diamonds. They may prioritise a larger appearance, a particular specification or the opportunity to create a more elaborate piece within budget.
At Share Jewellers, we believe the role of a trusted jeweller is not to make that decision for you. It is to explain the differences openly, answer your questions and ensure every diamond is accurately represented.
Whether you choose a natural diamond or a lab grown diamond, your jewellery should reflect your values, suit your budget and celebrate your own unique story.
