Production Process
Diamonds in the natural environment are generated under high-pressure high-temperature conditions where traces of carbon exist. It is generally thought that this process takes many years in places such as volcanos and where massive amounts of land are in turbulence. The have a high value and scarcity of its beauty is known to us all.
It became possible to manufacture synthetic diamonds about 50 years ago, and was achieved the first time in America by general electric (GE). Synthetic diamonds though difficult to produce is at times used for jewelry however it is not so common - unlike the use of synthetic diamonds for industrial use.
Synthetic industrial diamonds are produced from a relatively pure natural graphite containing carbon and the real challenge for producing memorial diamonds are that ashes contain many diamond making impurities such as bone and metals, therefore to produce a diamond to a jewel-class level without any additives, an advanced technology is needed. With its own carbon extraction technology (International Patent Pending), Algordanza has succeeded in extracting high-purity carbon from ashes.
In addition, Algordanza has made transparent its process to emphasize due diligence in its operations and procedures so that clients may have total confidence in our service. For more information about our facility, visit the「virtual tour」to understand more.
Manufacturing Process
Receipt in Switzerland
- In advance, individually and in boxes the pre-registered control number is applied. This makes mixups impossible.
- The details of the deceased and applicant are entered into the Algordanza database.
Analysis・Tests
- A composition analysis is conducted on the ashes. It checks the levels of carbon and other elements in the ashes without physical tampering. Generally, there is enough carbon in the ashes if an amount of 400g can be supplied.
Carbon Extraction
- A wet chemical and physical process is used to extract the carbon from the ashes.
- Carbon content can be extracted to a level of 90% purity.
- International patent-pending technology.
Conversion to Graphite
- Complete combustion of unneeded anorganic material.
- The carbon is converted to graphite via thermal treatment and gases are expelled.
- Structure of carbon is changed to form graphite.
Diamond Crystalization
- High-Temperature High-Pressure synthesis is applied.

| A growing cell is loaded that contains the graphite, special low melting alloy catalyst and seed-diamond. | Carbon will adhere to the seed-diamond where the graphite molecules are suspended in the molten material. | The result is a rough diamond attached to the diamond-seed. | After the diamond seed is removed, it takes the form of the above actual photo of a finished diamond. |
Cut and Polish
- The rough diamonds are then cut by highly skilled swiss craftsmen to the selected shape.
Inspection, certification
- The diamond is inspected and the size is recorded.
- The original ashes composition report is prepared that gurantees that the diamond was formed soley from the contents of the ashed.
- For Hong Kong and China clients, the diamond is delivered to a recognized lab such as GIA, IGI or Swiss Gemlab for diamond certification.
Laser Inscription, Jewelry Production
- If selected, an inscription is added to the diamond girdle and mounted on a setting of your choice.
