Is It Cheaper to Buy Lab Grown Diamonds?
In recent years, lab-grown diamonds have gained significant traction in the jewellery world, offering an appealing alternative to their naturally mined counterparts. But one question that comes up often is: are lab-grown diamonds actually cheaper? If you’re in the market for a diamond, understanding the pricing differences between lab-grown and natural diamonds is essential for making an informed decision.
In short: Yes. Lab-grown diamonds cost 60-80% less than mined diamonds at identical 4Cs grading. A 1.00ct F/VS1 Excellent-cut lab-grown round runs £1,400-£2,000 set in platinum; the same spec mined costs £6,500-£8,500. Identical Mohs 10 hardness, identical brilliance, identical GIA/IGI certification — paying less buys you no compromise in beauty.
In this article, we’ll explore whether lab-grown diamonds really are the more affordable option and why.
What Are Lab Grown Diamonds?
Lab-grown diamonds are created in a laboratory using advanced technology that replicates the natural conditions under which diamonds form beneath the Earth's surface. Two primary methods are used to grow these diamonds: High Pressure, High Temperature (HPHT) and Chemical Vapour Deposition (CVD). These processes produce diamonds that are chemically, physically, and optically identical to mined diamonds.
To the naked eye, lab-grown diamonds look exactly like natural diamonds, and even experts require specialised equipment to tell the difference. The key distinction lies in their origin—lab-grown diamonds are created above ground, while natural diamonds are formed over millions of years deep within the Earth.

Price Comparison: Lab Grown Diamonds vs Natural Diamonds
The main attraction of lab-grown diamonds for many buyers is their affordability. In general, lab-grown diamonds are 30-40% cheaper than natural diamonds.
This price difference is due to several factors, including the absence of expensive mining processes, the supply chain associated with natural diamonds, and the fact that lab-grown diamonds are produced more efficiently in a controlled environment.
For those looking to get a larger or higher-quality stone on a budget, lab-grown diamonds offer an attractive solution. For example, with the same budget, you could purchase a one-carat natural diamond with a certain clarity and colour, or you could opt for a lab-grown diamond of the same size but with superior clarity and colour.
This ability to stretch your budget makes lab-grown diamonds an increasingly popular choice, especially for engagement rings and other fine jewellery.

Why Are Lab Grown Diamonds Cheaper?
No Mining Costs
One of the primary reasons lab-grown diamonds are less expensive is that they eliminate the costly process of mining. Mined diamonds require extensive excavation, labour, and transportation, all of which contribute to their higher price.
Lab-grown diamonds, on the other hand, are produced in a laboratory setting, cutting out the environmental and logistical costs associated with mining. Also, lab-grown diamonds avoid the ethical concerns linked to traditional diamond mining, such as the issue of conflict diamonds.
For many, this ethical aspect makes lab-grown diamonds an even more appealing option, offering peace of mind along with a lower price point.
Technological Efficiency
As technology has advanced, the processes for creating lab-grown diamonds have become more efficient and cost-effective. What was once a slow and costly method of diamond production has rapidly improved, leading to lower production costs, which are passed on to the consumer. As demand for lab-grown diamonds continues to rise, this increased efficiency further drives down prices, making them an even more affordable option compared to natural diamonds.
Market Demand
Lab-grown diamonds are becoming more accepted and sought after in the jewellery market, but they still don’t command the same premium as natural diamonds. This is largely due to the perception of rarity—natural diamonds are finite, while lab-grown diamonds can be produced continuously.
As a result, natural diamonds often hold more value in terms of resale, but for those more focused on upfront cost and getting the best value for their money, lab-grown diamonds present an excellent option.

Factors That Influence the Cost of Lab Grown Diamonds
The 4 Cs (Cut, Colour, Clarity, Carat Weight)
Just like natural diamonds, lab-grown diamonds are graded based on the 4 Cs: cut, colour, clarity, and carat weight. These factors heavily influence the price of both types of diamonds. A lab-grown diamond with excellent cut, high clarity, and large carat weight will still be more expensive than a smaller or lower-quality lab-grown diamond.
However, even when comparing high-quality lab-grown diamonds to natural diamonds, the lab-grown option will still be significantly cheaper.

Diamond Shape and Customisation
The shape and cut of a diamond also affect its price. Round diamonds, for instance, tend to be more expensive due to the amount of rough diamond lost during the cutting process. Lab-grown diamonds offer more flexibility in terms of shape and size, and the lower price point means that buyers have more freedom to customise their jewellery to suit their personal preferences without breaking the bank.
For example, pear-shaped lab-grown diamonds and princess cut lab-grown diamonds are stunning and affordable alternatives to natural diamonds.
Retailer Markups
Retailer markups can differ between lab-grown and natural diamonds. While both types of diamonds are subject to retailer pricing strategies, lab-grown diamonds often come with lower overheads, which translates to more competitive pricing for consumers.
The growing availability of lab-grown diamonds from various retailers has also driven prices down, making them more accessible to a wider range of buyers.
Long-Term Cost Considerations
Resale Value
One of the drawbacks of lab-grown diamonds is their resale value. Natural diamonds tend to hold their value better due to their rarity and long-standing market reputation. Lab-grown diamonds, because they can be produced in greater quantities, typically have lower resale value.
While this may be a concern for some, it’s worth considering that most diamond jewellery is purchased for sentimental reasons, rather than for its resale potential.
Maintenance and Longevity
When it comes to durability, lab-grown diamonds are just as strong and long-lasting as natural diamonds. Both types of diamonds rank a 10 on the Mohs scale, making them resistant to scratching and damage. With proper care, lab-grown diamonds will maintain their brilliance and beauty for a lifetime.
From a long-term perspective, this means that both lab-grown and natural diamonds are equally durable, requiring minimal maintenance over the years.
Is Buying a Lab Grown Diamond Worth It?
Whether or not buying a lab-grown diamond is worth it depends on what you’re looking for in a diamond. If you prioritise affordability, ethical sourcing, and customisation, lab-grown diamonds are an excellent choice.
They offer the same stunning sparkle and durability as natural diamonds, but at a significantly lower cost. On the other hand, if you place greater value on rarity, tradition, and potential resale value, a natural diamond might be more suitable for you. For many buyers, lab-grown diamonds provide an affordable luxury that allows them to choose larger, higher-quality stones without compromising their budget.
They’re perfect for those who want a beautiful, timeless piece of jewellery that aligns with modern values of sustainability and ethical sourcing.

Lab Grown Diamonds Offer Affordable Luxury
In summary, lab-grown diamonds are undeniably cheaper than natural diamonds. Their lower price stems from the absence of mining costs, advances in technology, and market factors that allow for more efficient production.
While they may not hold the same resale value as natural diamonds, they provide an affordable, ethical, and high-quality alternative for those looking to make a special purchase. Whether you’re buying an engagement ring, a pendant, or a pair of earrings, lab-grown diamonds offer brilliant value without compromising on beauty or longevity.
