What are artificial diamonds?

Artificial or synthetic (lab-grown) diamonds are real diamonds grown in a laboratory. They possess the same chemical and physical properties as naturally mined diamonds—including hardness, brilliance, and sparkle.

How are artificial diamonds made?

There are two established processes: HPHT (High Pressure High Temperature) and CVD (Chemical Vapor Deposition). Fejn relies on the CVD process, in which a diamond crystal "regrows" layer by layer in a controlled manner – ensuring consistently high quality and responsible origin.

How much do artificial diamonds cost at fejn?

Prices depend on the 4Cs (carat, cut, color, clarity) and the jewelry design. As a guideline: Individual pieces with lab-grown diamonds at fejn start at approximately €199 up to approximately €2,500 – depending on the model and design.

Since when have artificial diamonds existed?

Research into artificial diamonds has been ongoing for decades; modern HPHT and CVD processes now enable jewelry quality with the same properties as natural diamonds – which is why fejn consistently relies on lab-grown diamonds.

How expensive are artificial diamonds compared to natural diamonds?

Lab-grown diamonds offer the same sparkle and material quality—often with a slightly more attractive price-performance ratio because the supply chain is shorter and more transparent. At fejn, you'll find a dedicated collection of lab-grown diamond jewelry with clearly stated prices for each model.

Are fejn’s artificial diamonds conflict-free?

Yes. Because lab-grown diamonds are created entirely in a laboratory, they are automatically conflict-free. At fejn, we also pay attention to transparent supply chains and sustainable production standards.

Do artificial diamonds have the same quality as natural ones?

Yes. Chemically, physically, and optically, they are identical. The only difference lies in their origin: naturally in the earth or deliberately created in a laboratory. fejn selects only high-quality, tested lab-grown diamonds.

How do I care for fejn jewelry with artificial diamonds?

Care is the same as for natural diamonds: gently clean with lukewarm water, mild soap, and a soft brush. Store jewelry in a dry place and protect it from chemicals.

Does fejn offer certificates for artificial diamonds?

Yes. All lab-grown diamonds larger than 0.5 carats at fejn come with an official IGI certificate of authenticity and quality, documenting the 4C values.

Laboratory-grown diamonds

Unlike their naturally occurring counterparts, which formed millions of years ago under intense heat and immense pressure deep within the Earth, synthetic diamonds are grown in a laboratory. However, lab-grown diamonds are by no means imitations! They possess the same properties as their naturally occurring counterparts, both chemically and physically. Lab-grown diamonds consist of 100% carbon and are just as hard as the gemstones formed deep within the Earth.

Once the laboratory-grown process is complete, such a diamond can be processed and cut as desired. Synthetic diamonds thus eliminate the risks associated with traditional diamond mining. For these gemstones, which were first discovered in the fourth century BC, a new era is beginning!

How synthetic diamonds are made

But how exactly do lab-grown diamonds work? There are essentially two ways to produce synthetic diamonds: In the first production method, known as high temperature high pressure (HPHT), carbon particles are formed into a diamond under high pressure and at high temperatures in a pressure chamber. The second production method, called chemical vapor deposition (CVD), involves growing a synthetic diamond from an existing piece of the gemstone. A new, artificial diamond is created through a complex vapor process. At fejn, we use the CVD method to produce synthetic diamonds. We also ensure that our energy production is environmentally friendly. The result is a sustainable gemstone that benefits everyone.
