Production

Diamonds grow in a natural ambiance where the crystal synthesis is possible due to high pressure and high temperature. Since approx, 50 years it is possible to produce urban diamonds. To create urban diamonds in a high quality for jewelry was much more complicated and cost-intensive compared with digging.

The production of diamond out of carbon extracted out of ashes is extremely complicated compared with industrial diamonds out of ultrapure carbon. To make possible the production of diamonds solely out of cremated ashes - guaranteed without any admixtures - a special method had to be developed. Also our machines have been developed for this application.  

Together with academics from the diamond synthesis-sector Algordanza has developed the method to make possible the growth of memorial diamonds. The DIN EN ISO 9001 certification gives you the guarantee of process.
 


Receiving and Initial Process of the Ashes

Directly upon receipt of the ashes, the ashes will be marked with serial number, thoroughly chemically examined, listed in the audit certificate and boxed. A mix-up of ashes is not possible.

 

 

 

Chemical analysis

In our laboratory the analysis of the chemical structure of the cremation ashes takes place. This analysis is on the one hand necessary for steering the subsequent physical and chemical processes. On the other hand this analysis documents the origin of the memorial diamond out of the remitted cremation ashes.

 

 

 

 

Carbon preparation

The different potassic and calcium compounds (about 85% of the ash volume) are extracted from the carbon by means of chemical and physical procedures. That happens by using strong acids and leaches. The carbon gained in this procedure forms the basis for the subsequent synthesis in the especially constructed synthesis facility.

 

 

 

 

Graphite preparation

The carbon is transformed under high pressure and temperature into graphite. Thereby generated gases are immediately discharged. Afterwards the cleaning of the generated graphite is carried out. That is now the starting bases for the actual diamond transformation.

 

 

 

Synthesis

For the production of these unique diamonds, a modified technique with HPHT (High Pressure High Temperature) technology is used.

1. Graphite is prepared for diamond transformation.

2. For initialising of the growth process, a diamond crystal is added.

3. Around the start crystal, more crystals are formed. The duration of growth depends on the requested size of the diamond.

4. The rough diamond will be taken out of the machine and the start crystal will be cut off.

 

 

 

Cut and polish

Cut and polish are executed by experienced diamond points.

 

 

 

 

Quality control and certificate

A strict quality control is carried out and the certificate with chemical analysis will be issued. Therein following values are noted: genuineness, weight, cut and colour of the diamond. Also the determining chemical composition and the guaranteed origin of the diamond out of the cremation ashes are confirmed.

 

 

Laser inscription

At request of the client, the diamond can be engraved by micro laser inscription. The diamond is packaged in a noble box, optionally the box can be printed according to your wishes.
