Recently lab created diamonds have become quite popular in the world of jewellery, offering buyers an ethical and less expensive option compared to natural diamonds. One common query that arises is; What is the lifespan of lab grown diamonds? This detailed guide will delve into the longevity, durability and maintenance of lab created diamonds, providing you with all the details required to make a thought out choice about these gems.
Understanding Lab-Grown Diamonds: A Brief Introduction
Lab-grown diamonds, also known as cultured diamonds, are created in controlled laboratory environments that replicate the natural diamond-forming process. These gems are chemically, physically, and optically identical to their natural counterparts, with the main difference being their origin.
The rising popularity of lab-created diamonds can be attributed to several factors:
- Ethical sourcing: Lab-grown diamonds eliminate concerns about conflict diamonds.
- Environmental impact: They typically have a smaller carbon footprint than mined diamonds.
- Cost-effectiveness: Lab-grown diamonds are often 20-40% less expensive than natural diamonds of similar quality.
- Customization: The controlled environment allows for more variety in colour and size.
- Technological advancements: Improved production methods have led to higher quality lab-grown diamonds.
The Lifespan of Lab-Grown Diamonds: Fact vs. Fiction
One of the most common questions about lab-grown diamonds is whether they last as long as natural diamonds. The short answer is: yes, lab-grown diamonds are just as durable and long-lasting as natural diamonds.
Here are some key facts about the longevity of lab-grown diamonds:
- Lab-grown diamonds have the same chemical composition as natural diamonds (pure carbon in a crystalline structure).
- They score a perfect 10 on the Mohs scale of mineral hardness, just like natural diamonds.
- The internal structure of lab-grown diamonds is identical to that of natural diamonds, ensuring similar durability.
- Lab-grown diamonds do not degrade or lose their sparkle over time under normal conditions.
It's important to dispel the myth that lab-grown diamonds somehow "disappear" or degrade over time. This misconception likely stems from confusion with other diamond simulants like cubic zirconia, which can cloud or change colour over the years. Lab-grown diamonds, being true diamonds, do not suffer from these issues.
The Science Behind Lab-Grown Diamond Durability
To truly understand how long lab-grown diamonds last, we need to delve into the science behind their creation and structure. This understanding will help explain why lab-grown diamonds are just as durable as their natural counterparts.
Chemical Composition and Structure
Lab-grown diamonds are made of pure carbon atoms arranged in a crystal structure called a diamond cubic. This structure is what gives diamonds, both natural and lab-grown, their exceptional hardness and durability.
The creation process of lab-grown diamonds involves two main methods:
- High Pressure High Temperature (HPHT): This method mimics the natural diamond-forming process by subjecting carbon to extreme pressure and temperature.
- Chemical Vapour Deposition (CVD): This newer technique involves growing diamond layers from a hydrocarbon gas mixture.
Both methods result in diamonds with the same atomic structure as natural diamonds, ensuring identical durability. The choice between HPHT and CVD often depends on the desired characteristics of the final diamond, as each method has its strengths in producing certain colours or clarities.
Hardness on the Mohs Scale
The Mohs scale of mineral hardness ranges from 1 (softest) to 10 (hardest). Diamonds, including lab-grown ones, are at the top of this scale with a perfect 10 rating. This means that only another diamond can scratch a lab-grown diamond.

This exceptional hardness is what allows lab-grown diamonds to maintain their polish and facet edges over time, contributing to their long-lasting beauty.
Resistance to Scratching, Chipping, and Breaking
While lab-grown diamonds are extremely hard, it's important to note that hardness doesn't equal toughness. Diamonds can chip or break if struck at the right angle with sufficient force. However, this is true for both natural and lab-grown diamonds and is more a result of the crystal structure than the diamond's origin.
The crystal structure of diamonds, with its tetrahedral arrangement of carbon atoms, provides excellent resistance to scratching and wear. However, this same structure can make diamonds somewhat brittle if struck along certain planes of weakness known as cleavage planes.
It's worth noting that the risk of chipping or breaking is minimal under normal wear conditions. Most diamond jewellery, whether made with natural or lab-grown stones, will last for generations with proper care.
Everyday Wear and Tear: How Lab-Grown Diamonds Hold Up
When you buy a lab-grown diamond ring, necklace, or earring, you're investing in a piece that's designed to last. But how do these gems fare in daily life?
