Laboratory Grown Diamonds - whats behind this new jewelry trend?

Responsible material selection and manufacturing have been part of fejn since day one. That is why today, we'd like to tell you more about our laboratory-grown diamonds. For our new designs, we rely on lab-grown diamonds with origins we can document and trace.

Previously, we also used natural diamonds. By making the switch to lab-grown diamonds, we consciously chose a sourcing path that allows us greater control and traceability.

Synthetic diamonds—the sparkling alternative

Lab-grown diamonds are created under controlled conditions in a laboratory, allowing their origin to be traced through documented sources. Using advanced technologies, these diamonds possess the exact same essential chemical, physical, and optical properties as natural diamonds.

What is a Laboratory Grown Diamond?

A laboratory-grown diamond is a diamond grown in a lab. It possesses the exact same essential chemical, physical, and optical properties as a natural diamond. Through specialized processes, the diamond grows under controlled laboratory conditions before being cut, polished, and processed.

How are lab-grown diamonds made?

There are various methods for manufacturing laboratory-grown diamonds. For our diamonds, the CVD (Chemical Vapor Deposition) process is used. In a controlled laboratory environment, a new diamond grows layer by layer from a small diamond seed with the help of carbon-rich gases.

How do diamonds form in nature?

Natural diamonds are formed deep within the Earth's mantle, where high pressure and extreme heat turn carbon into diamond crystals over millions of years. They usually reach the Earth's surface through magmatic processes—for instance, when kimberlite or lamproite rocks rise from great depths. Tectonic activity can also transport diamonds upward from deeper rock layers, after which they are extracted through traditional mining operations.

Lab-grown diamonds—real diamond, controlled origin

Sparkle and conscious material selection don't have to be mutually exclusive. With lab-grown diamonds, we can design jewelry pieces featuring real diamonds while transparently documenting their origin.

Our lab-grown diamonds are created under controlled conditions and sourced through documented channels. Furthermore, we evaluate our suppliers and sourcing channels as part of our risk-based due diligence processes.

This is how we combine the sparkle of a diamond with what matters most to us at fejn: clean design, traceable materials, and a responsible approach to our supply chain.
