Lab-Grown vs. Natural Diamonds: Pros and Cons

In the modern era, buying loose diamonds can be quite daunting. The abundant options including shapes and styles make it even more challenging. For those drawn to the timeless appeal of diamonds, there is now an additional consideration: Should you choose a natural diamond or opt for lab-created diamonds?

You must understand the distinctions between lab-grown and naturally mined diamonds to make an informed decision. Let’s explore their differences and consider the pros as well as cons associated with each.

What is the main difference between lab-grown diamonds and natural diamonds?

To ensure consumer confidence and clarity in their purchases, a range of instruments are available to differentiate natural diamonds from synthetic ones. Additionally, legal definitions, advertising guidelines, and certifications exist to ensure accurate information for consumers. 

Industry professionals have long relied on specialized laboratory equipment to examine growth patterns, composition, nitrogen content, fluorescence, and spectral signature. These factors help determine whether a diamond originated from the Earth’s mantle or was manufactured in a factory.

For instance, the extended duration of impurities in natural diamonds formed deep within the Earth can lead to distinctive responses to ultraviolet light.

There has been extensive research to develop screening and detection instruments capable of reliably identifying all laboratory-grown diamonds.

So let us explore what are the pros and cons of both diamonds: 

Lab diamonds vs. real diamonds

Pros of Lab Diamond 

1. Replicates the authentic appearance 

Only lab-created diamonds can truly replicate the authentic appearance and texture of a diamond, despite the existence of other diamond imitations. This is due to their identical chemical composition, optical properties, and physical characteristics to natural diamonds.

2. Affordable price 

Opting for a lab-created diamond enables you to obtain a larger stone at a more affordable price point. Typically, these diamonds cost 30-50% less than those mined from the earth, as the manufacturing process eliminates lengthy supply chains and expensive mining expenses.

3. Eco-friendly

In addition to being cost-effective, lab-created diamonds are also conflict-free and eco-friendly. Their origin can be traced back to the specific laboratory where they were produced. Although energy is utilized in the creation of lab diamonds, their environmental impact is significantly reduced compared to mined diamonds, which harm ecosystems, landscapes, and communities.

Ultimately, lab-created diamonds are readily available and represent an ethical choice for those seeking diamonds. However, a few cons of these diamonds are discussed in the next section. 

Cons of Lab Diamond 

1. Limited resale value

Diamonds, in general, tend to have weak resale value, and this applies to lab-grown diamonds as well. Lab-created diamonds can have a limited resale value. 

2. Lack of rarity

If you value rarity, the fact that lab-grown diamonds are mass-produced can be seen as a drawback. They do not possess the uniqueness and individuality of one-of-a-kind stones.

3. Potential for misconceptions

When purchasing lab-created diamonds, it’s important to be prepared for occasional rumors or misconceptions that may arise. Some people might mistakenly perceive lab-grown diamonds as fake, or even associate their choice with being frugal or unwilling to invest in a natural diamond.

Now that you are aware of the pros and cons of lab-grown diamonds, let us throw some light on natural ones:

Pros of Natural Diamonds 

1. Unique and rare

Natural diamonds possess an unparalleled quality of uniqueness. No two diamonds are alike, as each one holds a distinctive geological story, making them exceptionally rare and individual. This inherent rarity often contributes to the sentimental value associated with these precious stones.

2. Exceptional durability

Through the intense forces of pressure and heat endured over billions of years, natural diamonds have acquired hardness and durability, solidifying their position as one of the toughest naturally occurring substances on our planet.

3. Long-term value

Natural diamonds frequently maintain their value over time, making them a compelling choice for those seeking an investment piece.

Cons of Natural Diamonds 

1. Environmental impact

The process of mining natural diamonds carries a substantial environmental impact, which encompasses activities such as deforestation, soil erosion, and disruption of local ecosystems.

2. Cost

When compared to lab-grown diamonds, natural diamonds tend to be more expensive. This is primarily attributed to the costs associated with mining, transportation, and processing involved in obtaining natural diamonds.


Choosing between natural and lab-grown diamonds is a deeply personal decision influenced by various factors, including budget, ethical beliefs, environmental considerations, and personal preferences. It is crucial to carefully assess the advantages and disadvantages of both options before making a purchase. In case you need more information, you can also check our buying guide.
