The Difference Between Natural and Lab-Grown Diamonds

The biggest difference between natural diamonds and lab-grown is their origin story.


Origins: Natural diamonds are formed deep within the Earth's mantle under extreme heat and pressure over billions of years. They are brought to the surface through volcanic eruptions and are mined from various locations around the world, including Africa, Russia and Canada.


Alternatively, lab-grown diamonds, also known as synthetic or cultured diamonds, are created in controlled laboratory environments using two primary methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). These processes replicate the natural conditions under which diamonds form, producing crystals that are chemically, physically and optically identical to natural diamonds.


Physical and Chemical Properties: Both natural and lab-grown diamonds are composed of pure carbon arranged in a crystal lattice structure, which gives them their exceptional hardness, durability and brilliance. They are virtually indistinguishable from each other to the naked eye and require specialized equipment to differentiate between the two. To the naked eye, they have the same brightness, fire and scintillation that makes a diamond so desirable. 

Reasons to Choose Natural Diamonds

Rarity and Tradition: Natural diamonds are cherished for their uniqueness and rarity. Each natural diamond is a product of millions of years of natural processes, making it a one-of-a-kind symbol of endurance. Many people are attracted to the tradition and timeless appeal associated with natural diamonds.


Perceived Value: Natural diamonds have long been associated with luxury and status. They often hold their value well over time, making them not only a sentimental purchase but also a potential investment.


Unique Characteristics: Each natural diamond is a singular creation of nature, with unique inclusions and imperfections that tell a story of its geological journey. These natural characteristics add to the diamond's charm and individuality.

Reasons to Choose Lab-Grown Diamonds

Cost-Effectiveness: Lab-grown diamonds are typically 20-40% less expensive than their natural counterparts. This cost advantage allows consumers to purchase larger or higher-quality diamonds within the same budget, making luxury more accessible.


Lack of Inclusions: Because they are created in a lab, lab-grown diamonds are less likely to have inclusions or internal fractures. Because they are created in a lab, lab-grown diamonds are less likely to have inclusions or fractures, which can make them more durable; however, it’s important to note that both natural and lab-grown diamonds are incredibly durable and capable of withstanding everyday wear and tear.


Ethical Considerations: Lab-grown diamonds are often marketed as a more ethical choice because their production does not involve mining, which can be associated with environmental degradation and labor issues. Consumers who are concerned about the ethical implications of their purchases may prefer lab-grown diamonds for their reduced environmental and social impact.
