The term lab grown diamond is becoming increasingly common. These diamonds are created in a laboratory rather than extracted from deep within the earth. Yet, they are not imitation or fake. A lab grown diamond has the same chemical composition, hardness, and brilliance as a natural diamond.
But what exactly is a lab grown diamond, how is it made, and how does it differ from a natural diamond? In this blog, we explain the main differences.
What is a lab grown diamond?
A lab grown diamond is a real diamond formed under controlled conditions in a laboratory. The same natural process that creates diamonds deep within the earth is replicated.
The end result, like a natural diamond, consists entirely of crystallized carbon. As a result, both have the same hardness, clarity, light refraction, and brilliance.
How is a lab grown diamond made?
There are two commonly used production methods: HPHT (High Pressure High Temperature) and CVD (Chemical Vapor Deposition). Both techniques ensure that carbon builds up layer by layer into a real diamond.
Although the production process is different from nature, the end result at a molecular level is almost identical to a natural diamond.
The difference with a natural diamond
The biggest difference is not in the stone itself, but in its origin. A natural diamond is formed deep within the earth's crust under immense pressure and heat over millions to billions of years. Due to volcanic activity, the stone eventually comes closer to the earth's surface.
A lab grown diamond is created within a few weeks in a laboratory. This makes production much more controllable and less dependent on rare natural finds.
Can they be distinguished with the naked eye?
No. Even an experienced jeweler usually cannot distinguish between a natural and a lab grown diamond by simply looking.
Special equipment is needed to identify subtle differences in the crystal's growth. Therefore, both types of diamonds are also certified separately.
Are lab grown diamonds real diamonds?
Yes. A lab grown diamond is officially a diamond. It consists of the same material as a natural diamond and also achieves a hardness of 10 on the Mohs scale.
This means it is just as scratch-resistant and has the same brilliance. The well-known assessment criteria – the 4 C's (carat, color, clarity, and cut) – are also applied to lab grown diamonds.
Why do people choose a lab grown diamond?
For many people, price plays an important role. Because lab grown diamonds can be produced more efficiently, they are often significantly more affordable than comparable natural diamonds.
In addition, some people consciously choose a lab grown diamond because of its origin. They appreciate that the stone does not come from a mine.
A larger stone within the same budget
Because the price is usually lower, it is often possible to choose a larger or higher quality diamond within the same budget. This makes lab grown diamonds popular for engagement rings and other jewelry where the stone is central.
Do natural diamonds still have advantages?
For many people, a natural diamond has a special appeal because it is millions of years old. The idea that a stone has made such a long journey through the earth gives it extra emotional value for some.
In addition, natural diamonds are often considered rarer, as their availability depends on natural deposits.
Which choice suits you best?
There is no right or wrong answer. The choice mainly depends on what you find important.
- Do you want the special origin and history of a natural diamond? Then a natural diamond is probably a better fit.
- Do you find appearance, quality, and price more important than origin? Then a lab grown diamond can be an excellent choice.
Whichever variant you choose: both are real diamonds with the same brilliance, hardness, and durability.
Whether you choose a natural diamond or a lab grown diamond, ultimately it's all about the meaning the piece of jewelry has for you. Both offer the same brilliance and durability, but each with its own story.
