Introduction to Lab-Grown Diamonds
Lab grown diamonds, also referred to as cultured diamonds, are diamonds that are crafted in a lab setting rather than being extracted from the ground. These lab grown diamonds mirror natural diamonds in their chemical composition, physical attributes and appearance but are made using controlled methods rather than natural geological processes.
The process of creating lab grown diamonds typically involves utilising technology to simulate the pressure and high temperature conditions found deep within the Earth's mantle. This enables scientists to grow diamond crystals from a starting diamond or carbon rich materials. The resulting lab created diamonds have the same crystal structures, chemical compositions and optical properties as mined diamonds [1].
Unlike diamonds that form over periods spanning billions of years, lab grown diamonds can be manufactured within weeks or months. This accelerated production timeline allows for control over the diamond's characteristics like size, cut, colour and clarity. Lab grown diamonds have gained popularity as an environmentally friendly option compared to traditionally mined diamonds, particularly appealing to consumers concerned about sustainability and cost.
There are two main methods used to create lab-grown diamonds: High Pressure High Temperature (HPHT) and Chemical Vapour Deposition (CVD). HPHT involves subjecting a small diamond "seed" to extremely high temperatures and pressures, replicating the natural diamond formation process. On the other hand, CVD uses a gas-based method to grow diamond crystals from a carbon-rich gas mixture.
Both lab grown diamonds produced through HPHT and CVD are considered genuine diamonds, and they are often indistinguishable from their mined counterparts without specialised gemmological testing. However, the production costs and environmental impact of lab-grown diamonds can be significantly lower than those of mined diamonds.
The Costs of Lab-Grown Diamonds
Factors Affecting Lab-Grown Diamond Prices
The cost of lab-grown diamonds can differ significantly based on several key factors:
- Size and Carat Weight: Larger lab grown diamonds, especially those exceeding 1 carat typically demand higher prices, per carat. On the other hand, smaller lab grown diamonds, below 1 carat are usually more budget friendly.
- Cut, Colour, and Clarity Grades: Like natural diamonds, the quality of a lab-grown diamond's cut, colour, and clarity grades will impact its price. Diamonds with higher grades in these aspects will be more expensive.
- Brand and Retailer: The pricing of a lab grown diamond can also be influenced by the brand or retailer selling it. Established brands with reputations may charge higher prices compared to lesser known sellers.
- Production Costs: The expenses involved in manufacturing lab grown diamonds may vary based on the technology equipment used, as well as the energy and materials required. Adopting more efficient production methods can contribute to price reductions.
Average Prices for Lab-Grown Diamonds
According to recent industry data, the average price for a 1-carat lab-grown diamond ranges from around $3,000 to $6,000. In comparison, the average price for a 1-carat natural diamond usually ranges between $6,000 and $10,000 [2].
For smaller lab-grown diamonds, the prices are more budget friendly. A 0.5 carat lab grown diamond could be priced from $1,500 to $3,000 while a 0.25 carat lab created diamond might be available for $800 to $1,500.
When it comes to jewellery like engagement rings and necklaces made with lab grown diamonds, there's a cost advantage over their counterparts. An engagement ring featuring a 1 carat lab created diamond may cost $5,000 to $8,000 compared to a ring with a natural diamond that could range from $10,000 to $20,000.
It's important to note that the price range for lab-grown diamonds can vary depending on the specific retailer, brand, and the diamond's quality characteristics. Some high-end lab-grown diamond brands may charge prices that are closer to those of mined diamonds, while more budget-friendly options can offer significant savings.
Costs Compared to Mined Diamonds
The main reason why lab grown diamonds are priced differently from mined diamonds is due to how they're produced. Mined diamonds involve a process that includes exploration, excavation and processing to extract them from the Earth's crust, which is both expensive and time consuming [3]. On the other hand, lab grown diamonds can be created within a weeks or months using advanced manufacturing methods that are becoming more efficient and cost friendly.
Moreover concerns related to the environment and ethics surrounding diamonds, such as resource depletion, energy intensive mining practices and the possibility of conflict diamonds can contribute to the costs of these diamonds. In contrast lab grown diamonds are often promoted as a socially responsible option, which can impact their perceived value and pricing.
To illustrate the cost differences, consider the following comparison:
|

As shown in the table, lab-grown diamonds can offer significant cost savings compared to mined diamonds, while also providing environmental and ethical benefits. This has made them an increasingly attractive option for consumers who are looking to balance quality, affordability, and social responsibility.
Benefits of Choosing Lab-Grown Diamonds
Environmental Advantages
One of the primary benefits of choosing lab-grown diamonds is their significantly reduced environmental impact compared to mined diamonds. The diamond mining process can be highly energy-intensive, requiring large amounts of fossil fuels and water, and can also lead to habitat destruction, soil erosion, and water pollution. Whereas, the production of lab-grown diamonds typically requires much less energy and water, and does not cause as much harm to the environment.
According to a study by the Sustainability Accounting Standards Board, the greenhouse gas emissions associated with the production of a 1-carat lab-grown diamond are approximately 0.28 tons of carbon dioxide equivalent, compared to 57.6 tons of carbon dioxide equivalent for a mined diamond [4]. This significant difference in environmental impact is a major factor driving the increasing popularity of lab-grown diamonds among eco-conscious consumers.
In addition to the reduced carbon footprint, lab-grown diamond production also avoids issues like water scarcity and land degradation linked to mining practices. A study by the World Wildlife Fund found that the water used to produce a single mined diamond is equivalent to the amount of water a person drinks in 3.6 years. Lab-grown diamond production, on the other hand, can be designed to be a closed-loop system, minimising water usage and waste.
Moreover, the environmental impact of lab-grown diamond production can be further reduced by using renewable energy sources, such as solar or wind power, to power the manufacturing process. This can help to ensure that the diamonds are produced in a truly sustainable manner, making them an even more attractive option for environmentally conscious consumers.
Ethical Considerations
In addition to the environmental benefits, lab-grown diamonds also offer a more ethical alternative to mined diamonds. The diamond mining industry has long been associated with issues such as human rights abuses, child labour, and the trade in "conflict diamonds" that fund armed conflicts and civil wars. By choosing lab-grown diamonds, consumers can be confident that their purchase is not contributing to these unethical practices.
Lab-grown diamonds are also often marketed as a more transparent and traceable option, with detailed information available about their production and origin. This allows consumers to make more informed and ethical purchasing decisions, knowing that the diamonds they are buying are not associated with any human rights violations or other ethical concerns.
One example of a lab-grown diamond brand that prioritises ethical practices is Blackwell Jewellers. The company sources its lab-grown diamonds from manufacturers that adhere to strict social and environmental standards, and it provides customers with detailed information about the origin and production of each diamond [5]. This level of transparency and traceability is often lacking in the traditional mined diamond industry, making lab-grown diamonds a more appealing choice for ethically-minded consumers.
Customization and Personalization
One of the advantages of lab created diamonds is the ability to tailor and personalise the diamond to match the buyers requirements. Since lab grown diamonds are made in a controlled setting it's feasible to produce diamonds, with cuts, colours and clarity grades along with sizes and shapes. This customization option is especially valuable for designing engagement rings and other jewellery items.
Individuals looking to buy lab grown diamonds often have the opportunity to collaborate directly with retailers or manufacturers to craft a one of a kind diamond that aligns perfectly with their preferences and budget. Achieving this level of personalization isn't always feasible with mined diamonds due to the variations resulting from processes.
For example, Blackwell Jewellers offers a wide selection of lab-grown diamonds that can be customised to the customer's exact specifications. Customers can choose the size, cut, colour, and clarity of the diamond, as well as the setting and design of the jewellery piece. This allows for a truly personalised and meaningful purchase, whether it's for an engagement ring, a necklace, or any other special occasion.
In contrast, mined diamonds are often limited to the available inventory at a given retailer, and customers may have fewer options for customization. By choosing a lab-grown diamond, consumers can ensure that the final product is a unique and personal reflection of their style and preferences.

While buying lab grown diamonds online has gained popularity some consumers still prefer to visit a jewellery store to inspect the diamonds, in person. Many traditional jewellers now include lab grown diamond options in their collections giving customers the chance to compare diamonds side by side.
When buying lab grown diamonds in a store it's crucial to choose a knowledgeable jeweller who can provide detailed information about the diamonds specifications and origin. Customers should also be ready to negotiate prices and ask about any discounts or deals as prices in store can sometimes be flexible compared to listings.
One benefit of purchasing in store is the opportunity to physically examine the diamond and assess its quality under lighting conditions. This hands-on approach is especially valuable for customers who prefer seeing and touching the diamond before making a decision rather than relying solely on descriptions and photos.
Additionally, some local jewellers may offer custom design services, allowing customers to work with a professional to create a unique piece of jewellery incorporating a lab-grown diamond. This can be a valuable option for those seeking a truly personalised and one-of-a-kind piece.
Certification and Appraisal
Whether you're buying a lab-created diamond online or in a store it's important to make sure it comes with the certification from gemmological organisations like GIA or IGI. These certifications offer insights into the diamonds cut, colour, clarity and carat weight helping buyers make informed decisions.
In addition to certification, it's advisable to get an appraisal for a lab grown diamond especially if it's intended for an engagement ring or other high end jewellery piece. An appraisal can ensure that the diamond's worth is accurately assessed and that the price paid is fair.
When evaluating a lab-grown diamond's certification, consumers should look for the following information:
- Carat weight
- Cut quality (excellent, very good, good, etc.)
- Colour grade (D-Z scale)
- Clarity grade (Flawless to Included)
- Any additional characteristics or special features
By ensuring that a lab-grown diamond is properly certified and appraised, consumers can have confidence in the quality and value of their purchase, whether they are shopping online or in-store.
