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 to and the 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 create even more than one diamond.

The Creation of a
Memorial Diamond

Natural diamonds have been created under vast pressure and enormous heat in the depths of the earth. To create a Memorial Diamond 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 in a grave is desired or even (religio-)culturally required, the ALGORDANZA Hair Memorial Diamond is a unique addition.The ALGORDANZA Hair Memorial Diamond is a beautiful remembrance in case of a traditional burial on a graveyard.

We only use the Carbon extracted from the cremation ashes or hair to create one or more Memorial Diamonds consisting of 99.9% Carbon.

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.








Laser Inscription

Each ALGORDANZA Memorial Diamond made from ashes or hair is inscribed with the ALGORDANZA signet and its unique reference number. Additionally, a personal inscription may be engraved at a premium. The length of the message depends on the cut and the size of the Memorial Diamond (max. 50 characters).

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 60'000bar and a temperature of 1'400°C inside of the HPHT-machines. The bigger the diamond should become, 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.
Each ALGORDANZA Memorial Diamond is handed over with a certificate, giving information about origin of the Carbon, authenticity as well as other specific characteristics of the Memorial Diamond. Each certificate is signed by Rinaldo Willy, founder of ALGORDANZA.

Frequently Asked Questions (FAQ)

Yes – the ALGORDANZA memorial diamond shows the same physical, chemical and optical properties as a natural diamond. In our production site in Switzerland we recreate the natural formation conditions. Thus, your individual ALGORDANZA Memorial Diamond can grow.

No – the size of the diamond depends on the duration of the process. The longer the remembrance diamond lasts in the growing phase, the bigger it becomes.

On average, the cremation of an adult human being generates 2’500 g of ashes. We need at least 500 g of these ashes for the synthesis of a cremation diamond.

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.

For the creation of a hair diamond we need at least 5g of hair.

For the creation this special remembrance jewel you can hand over a personal letter, diary or picture of the deceased person. The personal item along with the amount of ashes or hair available will be the basis for the synthesis of this unique remembrance diamond.

With our certificate, we guarantee the authenticity, weight, cut and colour of the diamond as well as the origin of the diamond from the Carbon source given to us.

Yes, we are able to create more than one diamond from the requested Carbon source. We can specify the number of possible diamonds after detailed analyses of the source in our laboratory.

The synthesis takes approximately 5-8 months from the receipt of the Carbon source and deposit of the prepayment. The synthesis of a diamond is a highly complex process and in some cases it can take more time.

The coloration depends on the element boron within the diamond. The more boron is bound to the carbon grid the more intense is blue coloration. We do not affect the coloring of the diamond. The unique blueish colouration emphasizes the uniqueness of your personal Memorial Diamond.

Yes – the age of the ashes or hair is not relevant for the synthesis.
