Lab-Grown vs. Natural Diamonds: What's the Difference?
Diamonds have long been a symbol of love, luxury, and lasting commitment, often regarded as the ultimate gemstone to celebrate special occasions. Whether adorning an engagement ring or serving as a meaningful family heirloom, these precious stones have captured hearts for centuries. But in recent years, a new contender has emerged in the world of fine jewelry: the lab-grown diamond. As more couples and jewelry enthusiasts become curious about these synthetic beauties, questions about their differences from natural diamonds abound.
In this blog post, we’ll explore everything you need to know about lab-grown diamonds and natural diamonds—from how they’re made to their ethical and environmental impacts, as well as their value and longevity. Our goal is to equip you with all the information you need to make an informed decision on which type of diamond best suits your lifestyle and values.

1. What Is the Difference Between a Lab-Grown Diamond and a Natural Diamond?
The most fundamental question on everyone’s mind: what really sets these two types of diamonds apart?
A natural diamond is a gemstone that forms over millions of years beneath the Earth’s surface, subjected to extreme pressure and heat. These diamonds are formed from carbon atoms that bond in a crystalline structure, creating the stunning gem that we recognize and adore. The beauty of natural diamonds lies in their rarity—only a handful of natural diamonds make it to the surface for human discovery and use.
On the other hand, lab-grown diamonds, also known as synthetic diamonds, are created in a laboratory using technological processes that simulate the natural conditions under which diamonds form in the Earth’s crust. The two primary methods used for creating lab-grown diamonds are High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Both methods use carbon atoms, just like natural diamonds, and result in diamonds with identical chemical properties, hardness, and brilliance.
So, in terms of appearance, chemical composition, and durability, lab-grown diamonds are virtually identical to natural diamonds. The difference lies primarily in their origins—natural diamonds are formed in nature, while lab-grown diamonds are created in a controlled environment.
2. Are Lab-Grown Diamonds Less Valuable Than Natural Diamonds?
This is one of the most frequently asked questions when comparing lab-grown diamonds vs. real diamonds. The answer depends on several factors, but the short version is: Yes, lab-grown diamonds are generally less expensive than natural diamonds.
While lab-grown diamonds are chemically identical to natural diamonds, the main reason for the price difference is rarity. Natural diamonds are rare and difficult to come by, which drives their price up. Lab-grown diamonds, on the other hand, are more abundant because they can be produced in a lab, making them less expensive to obtain. Additionally, lab-grown diamonds don’t have the same markup that natural diamonds do due to their scarcity.
That being said, lab-grown diamonds still retain their value, but they tend to appreciate at a slower rate than natural diamonds. Natural diamonds are considered a better investment in terms of long-term value, but lab-grown diamonds are an excellent option for those looking for a beautiful and ethical choice at a lower price point.
3. Are Lab-Grown Diamonds Environmentally Friendly?
When it comes to sustainability, lab-grown diamonds often take the lead over their natural counterparts. Natural diamond mining can be an environmentally destructive process, involving significant land excavation, water consumption, and energy use. In contrast, lab-grown diamonds require much less environmental impact during their creation.
The production of lab-grown diamonds generates less waste, uses fewer resources, and can be done with renewable energy, making them a more eco-friendly option overall. However, it's important to note that not all lab-grown diamonds are created equally. Some companies use renewable energy sources and implement sustainable practices in their production, while others do not. It's always a good idea to research the company’s ethical and environmental practices when purchasing a lab-grown diamond.
4. What Are the Ethical Implications of Lab-Grown vs. Natural Diamonds?
Ethical concerns are another significant consideration when purchasing a diamond, and many consumers are looking to make responsible choices in their jewelry purchases. Traditional diamond mining has long been associated with human rights violations, including child labor, unsafe working conditions, and exploitation in certain regions of the world. These issues have given rise to the "blood diamond" movement, where diamonds obtained through unethical practices are heavily scrutinized.
Lab-grown diamonds, however, offer a solution to this problem. Because they are produced in a controlled environment, lab-grown diamonds are free from the ethical concerns associated with diamond mining. For consumers who are passionate about making an ethical choice, lab-grown diamonds provide an attractive alternative to natural diamonds.

5. How Can You Tell the Difference Between a Lab-Grown Diamond and a Natural Diamond?
Despite their striking similarities, it can be challenging to distinguish between a lab-grown diamond and a natural diamond with the naked eye. The only real way to tell the difference is through advanced gemological testing.
Lab-grown diamonds are often identified by specific inclusions or traces of their manufacturing process, which can be detected by professional jewelers using specialized equipment, such as a microscope or a spectroscope. Most lab-grown diamonds will come with a certification from a gemological lab that clearly states their origin, so it's always a good idea to ask for this documentation when purchasing one.
6. Do Lab-Grown Diamonds Have the Same Durability and Quality as Natural Diamonds?
In terms of durability, lab-grown diamonds are just as strong as natural diamonds. Both types of diamonds rate a perfect 10 on the Mohs scale of hardness, which means they are incredibly resistant to scratching and damage. This makes both lab-grown and natural diamonds ideal for everyday wear, whether in an engagement ring, bracelet, or pendant.
The only real difference between the two is the way they were formed. While natural diamonds are created by geological processes over millions of years, lab-grown diamonds are created in a matter of weeks. But this doesn’t mean lab-grown diamonds are any less durable—they share the same strength, brilliance, and longevity as natural diamonds.
7. Which Should You Choose: Lab-Grown or Natural Diamonds?
The decision between a lab-grown and a natural diamond ultimately comes down to your personal preferences and values. If you are drawn to the timelessness and rarity of natural diamonds and are willing to pay a premium for them, a natural diamond may be the right choice for you.
However, if sustainability, ethical sourcing, and affordability are top priorities, a lab-grown diamond could be an excellent choice. Lab-grown diamonds offer all the beauty, brilliance, and quality of natural diamonds, but with a smaller environmental footprint and a more affordable price tag.
