Company History

The idea to isolate carbon from human cremation ashes and create from this carbon source a memorial diamond arose in 2003. The creation of synthetic diamonds from industrial carbon sources has been possible since the 1960's.

By virtue of the complexity of extraction of pure carbon and the diamond synthesis, a year of investigation about acceptance and technical possibilities followed the idea. In 2004, the Swiss company was founded.

Algordanza specialists developed the procedure through intense research and processes. Natural diamonds emerge under enormous pressure and high temperatures inside of the earth. In order to enable a diamond synthesis, these conditions have to be recreated.



Our diamond synthesis equipment are really powerful machines. Their potential is fully demanded for the creation of Memorial Diamonds. They have the ability to generate a pressure of 60’000 bar and temperatures of 1400° Celsius. This procedure is called high-pressure-high-temperature-one crystal-synthesis.

Through research cooperation with considerable universities in Europe, we have advanced, and will continually advance, the method of the diamond synthesis. Our goal is to extend the most state-of-the-art production site for synthetic diamonds in Switzerland.We are proud of the outcome of our long-time research work: Our own HPHT-machine prototype - it promises shorter growth times of our Memorial Diamonds.





Memorial Diamond Laboratory - International Headquarters

Algordanza is represented in over 30 countries and is worldwide, the only ISO certified producer of memorial diamonds. Our laboratory is located in Domat/Ems Switzerland. Notice the breathtaking Swiss Alps upon our doorsteps.

Each order is handled with respect and precision. Your memorial diamond is created in our own HPHT machines, inside our state of the facility. In Spring 2017, we had two new HPHT machines delivered and installed. The weight of the each machine had to be lifted with a crane!

International Partners & Representatives

We meet to discuss customer needs and experiences from each country. We understand and appreciate the responsibility we receive from the families we serve. Just as each person is unique, as is each Algordanza Memorial Diamond.
