Memorial Diamond Creation 

The ALGORDANZA Memorial Diamond shares its chemical, physical as well as optical features with natural diamonds. In order to create a Memorial Diamond, we simulate the natural environment in which a diamond grows over hundreds of years inside of the earth.

Process from Ashes or Hair to a Diamond

Carbon is the element of life and the foundation of each diamond consists of  up to 99.9% Carbon. Diamonds have been created under vast pressure and enormous heat naturally in the bowels of the earth. To create a diamond from human cremains or hair we have to simulate the same conditions.

For this we need to:

1. Isolate the Carbon from the ashes or hair

2. Transform the Carbon into Graphite 

3. Final transformation into a Memorial Diamond

Isolation of the Carbon

The human body consists of 20% of Carbon - the element of life.  For creation of one memorial diamond from ashes, we need at least 500g of the cremated remains.

Hair consists of around 50% Carbon. For the creation of one or more Memorial Diamonds we need therefore at least 5g of hair. If not enough cremated remains or hair are available, a second Carbon source such as a personal letter, diary or a picture can be used to isolate enough Carbon for the synthesis of at least one Memorial Diamond.  This isolated carbon is the foundation for the diamond growth following the example set by nature.

Conversion into Graphite

The Carbon solely from the remains of your loved one converts under high pressure and high temperature to graphite. The purified graphite is the foundation for the subsequent diamond transformation inside our own HPHT (High Pressure – High Temperature) machines.

Diamond Transformation

A diamond starter crystal within the growth cell triggers the growth of the Memorial Diamond. It is melted into a metal alloy and does not conjoin with the carbon isolated from the cremation ashes. More diamond crystals slowly crystalize on the surface of the starter crystal. The growth process takes weeks – depending on the desired size of the Memorial Diamond. The starter crystal is then removed from the surface of the synthetic rough diamond.


The diamond transformation happens in our own HPHT machines, uniquely constructed for us according to our structural plans based on experience and research. The machines feign the natural environment for the evolution of diamonds. The powerful machines have to create the pressure of 60'000 bar (870’000 psi) and between 1200 – 1400° C. After the removal of the growing cell from the machine, the rough diamond can be separated from the metal alloy.

Your personal memorial diamond will be hand-cut by experienced experts only.
