The ALGORDANZA Memorial Diamond is

A Symbol
of Love

A Memorial Diamond made from hair or ashes is the most beautiful and everlasting way to bid farewell to your loved one. Today, increasing mobility and globalization often complicate the regular visits and maintenance of a grave. Compared to traditional types of burials, the Memorial Diamond is a very personal monument of mourning, remembrance and joy.

Your Personal
Memorial Diamond

The ALGORDANZA Memorial Diamond reflects the uniqueness of the deceased. A remembrance diamond shines in exceptional blueish shades. A unique rough diamond is created solely out of the carbon of the hair or cremation ashes of the deceased. You can choose your preferred carbon source, size and cut of the Memorial Diamond. We can also create multiple diamonds from the cremation ashes or hair.

Turning Ashes into
Memorial Diamonds

Natural diamonds have been created under vast pressure and enormous heat in the depths of the earth. To turn cremation ashes to diamonds we have to simulate the same conditions. With our own HPHT-machines (High-Pressure-High-Temperature) we are able to do so. From cremated remains or hair we extract the carbon and grow the most special and unique memorial jewel.

A symbol of endless love and remembrance.

Next to the traditional burial the demand for cremation is increasing steadily worldwide. The cremated remains are then often stored in a graveyard or, where the law allows it, the ashes are scattered in nature. An ALGORDANZA Pure Memorial Diamond is a unique alternative or addition to the traditional urn interment.

In cases where a traditional burial is desired or even (religio-)culturally required, the ALGORDANZA Hair Memorial Diamond is a unique way to remember a loved one while still having a traditional burial.

We extract carbon from the cremation ashes or hair that is 99.9% pure and using this carbon to turn your loved one into a Memorial Diamond.

An ALGORDANZA Memorial Diamond is a memorable heirloom over generations for the remembrance of a beloved family member.

Memorial Diamond Colour

The ALGORDANZA Memorial Diamond shines in exceptional, different shades of blue. Each diamond glints in its own, unique blueish colour and is the manifestation of its uniqueness. The colour depends on the element Boron contained within the diamond. The more Boron embedded in the crystal grating of the diamond, the darker the blueish shade.

Memorial Diamond Cuts

The cutting of a diamond is a craft, since only the exact proportions of the diamond are able to unleash the exceptional sparkling. We entrust your personal Memorial Diamond only to sophisticated experts to cut it by hand. Choose your preferred cut or decide for a rough diamond – as the diamond uniquely formed itself.

How a Diamond is made from Ashes or Hair

Carbon is the element of life and the foundation each diamond consists of to 99.9% . 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 isolate the carbon from the cremated remains, transform it into graphite and finally turn it into a memorial diamond.

Cremation and Cremated Remains

Today cremation of a human body generally is done in two phases and can last up to three hours. Following cremation an adult will on average produce around 2 to 3kg cremated remains. The cremains consist of a vast number of chemical elements.

Carbon - the Element of Life

The human body consists of around 25% carbon or carbon compounds. During cremation most of the carbon escapes as gaseous carbon dioxide. The remaining carbon accounts for a weight portion of around 0.5 up to 2.5% of the cremated remains.

Carbon - Hair or Personal Items

Hair consists of around 50% carbon. If not enough cremated remains or hair are available, a second carbon source such as a personal letter, diary or a picture of the deceased can be used to isolate enough carbon for the synthesis of at least one memorial diamond.

Isolation of Carbon

To create a diamond, a multistage chemical process is necessary. Oxidic and possible metallic constituents of the cremated remains are removed wet chemically and the high-carbon indissoluble residue is isolated through filtration.

Growing Cell

The isolated carbon is the foundation for the subsequent diamond synthesis. The carbon is assembled into a special growing cell. The growing cell creates the perfectly isolated surrounding for the undisturbed growth of a memorial diamond in our HPHT-machine.

The growing cell is meticulously set into the HPHT-press. HPHT signifies High Pressure High Temperature. Our HPHT-presses are constructed specifically for ALGORDANZA's necessities and weighs more than 14 tons each.

Diamond Growth

The growing cell is exposed to a pressure of around 60'000 bar and a temperature of 1'400°C inside of the HPHT-machines. The larger the diamond should be, the longer the growing cell stays in the press; the duration of the growth process determines the size of the diamond.

Rough Diamond

At the end of the calculated duration of growth for the requested diamond size the growing cell is removed from the press. Inside of the cell core, in molten metal, the newly grown memorial diamond - so called rough diamond - is embedded.

Cut and Polish

According to the family's request the memorial diamond will be cut or handed over as a polished rough diamond. Cutting and polishing a diamond is a real craft and only made by experienced experts by hand. If the memorial diamond is requested as rough diamond, solely the abrasive start face of the diamond is polished.

Laser Inscription

Each hair or ashes diamond is engraved with a small laser inscription on the diamond's girdle. The laser inscription consists of the unique reference number of the order. On request an individual message can be engraved additionally to the reference number.

During cremation, the majority of carbon escapes as carbon dioxide. Inside the cremation ashes remains a carbon concentration of 1-5%. We are able to extract the carbon from the cremation ashes. This carbon will be the basis for the following diamond synthesis of a cremation diamond.
