Natural and lab-grown diamonds have the same appearance, hence, it is not possible for you to differentiate between them with your naked eyes. Even though they have the same appearance as well as physical and chemical properties, there are significant differences between them in terms of the origin, value, the time required for their formation, etc. Therefore, we list some of the important aspects that make lab grown diamonds different from natural ones.
The Origin
Mined diamonds are unique creations of nature. They form deep under the earth over millions or billions of years. Diamonds usually form in the earth’s mantle where the temperature and pressure are extremely high. Diamonds are formed by the crystallization of carbon atoms in the mantle of the earth. These crystals will be then brought to the earth’s crust through volcanic eruptions. Diamonds thus formed will be recovered from the earth’s crust through mining.
Lab-grown diamonds also require the same atmosphere that is needed for the formation of natural diamonds. But this atmosphere will be artificially created inside laboratories by scientists to encourage the production of diamonds.
Different processes are used for creating artificial diamonds including:
- High-Pressure High-Temperature (HPHT)
- Chemical Vapor Decomposition (CVD)
Therefore, both natural diamonds and lab-created diamonds greatly vary in terms of their origin.
The Time Required For Their Creation
Natural diamonds become truly unique and valuable because of the extremely long periods required for their formation. It takes millions and billions of years for a diamond to form under the earth and be delivered to the earth’s surface.
However, artificial diamonds only require a few weeks to complete their formation process. Hence, they can be produced at will and based on demand.
The Value
Natural diamonds have great value because of their uniqueness and rarity. These stones are very rare and there is also a limited supply of natural diamonds on the earth.
On the other hand, lab grown diamonds can be created based on demand, therefore, they are not unique or rare. So these stones have less value when compared to mined diamonds.
Price
Natural diamonds are very costly because of their great value and rarity. But lab-grown diamonds can be almost 30-40% less costly than natural ones which makes them more affordable. So if you are looking for engagement rings at less expensive rates, then these stones can be suitable for you.
Additionally, the resale value of lab-created diamonds can also be low in comparison with natural diamonds. But they can be a wonderful ethical and low-cost alternative to mined stones.
