Frequently Asked Questions About Ashes to Diamonds

- Cremation Diamonds - Ash Diamonds - Memorial Diamonds -

Yes – the ALGORDANZA Memorial Diamond has the same physical and optical properties as a natural diamond. In our production site in Switzerland we recreate the natural formation conditions so that your individual ALGORDANZA cremation diamond can grow.

We believe that losing a beloved animal companion can be just as heartbreaking as losing a family member. Therefore we have partnered with Semper Fides who are animal lovers like us, but have more experience with the loss of a precious pet.

Algordanza and Semper Fides understand the difference in size of pets compared to humans and therefore having different amounts of ashes or hair available which could affect diamond growth.

Algordanza is happy to take your inquiries about having pet cremation diamonds made, we will connect you with our friends at Semper Fides.

Our service starts at $3,699 CAD for a 0.3ct medium sized diamond. The price is determined by the carbon source, selected size and cut of your chosen cremation diamond.

No – the size of the diamond depends on the duration of the process. The longer the diamond stays in the growing phase, the larger it becomes.

The cremation of an adult can produce up to 4 kg of ash. It is not the volume of ash that is decisive for the creation of a memorial diamond, but its carbon content. As a rule, 500 grams of ash are enough for the production of one or more ash diamonds.

If you do not intend to scatter or bury the remaining ashes, the  entire cremains can be left in the production process until all of the cremation ashes are completely transformed. Otherwise, we send back the remaining ashes to the funeral home to comply with your wishes.

In special situations, such as cremation of small children or cremations with significant excess of oxygen, it can happen that the carbon in the cremation ashes given to us is insufficient to successfully grow one or more memorial diamonds. In these cases, after the carbon analysis, we contact the funeral home and/or the bereaved and find a common solution, such as a second source.

During cremation, a large part of the carbon escapes as gaseous carbon dioxide. The proportion by weight of the carbon remaining in the main combustion chamber is generally between 0.5% and 2.5% of the dry cremation ash. This can be proven by appropriately equipped laboratories. The carbon is isolated from the ash by a wet-chemical process or pyrolysis and serves as the basis for the later diamond synthesis.

Due to technical and legal reasons, a cremation always takes place in a coffin. Therefore, the cremation ashes will contain minor components of the coffin, clothing, as well as potential implants. It is technically impossible to separate and divide the cremation ashes including the carbon. As a result, the diamond lattice of the memorial diamond can contain some carbon atoms from the coffin or the clothing.

Approximately 5g of hair is required to grow one or more memorial diamonds.

For the additional carbon source of an ALGORDANZA Origin, hair, photos or letters can be used. The personal object should be directly related to the deceased.


With our certificate, we guarantee the authenticity, weight, cut and color of the diamond as well as the origin of 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 about 4-8 months beginning from the date of reception of the carbon source and the receipt of the payment. Nevertheless, the synthesis of a diamond is a highly complex process. In some cases, it can take more time. We assure you that quality and precision are our first priorities.

The coloration depends on the element boron within the diamond. The more boron that is bound to the carbon grid the more intense the blue coloration is. We do not influence the coloring of the diamond. The unique blueish coloration emphasizes the uniqueness of your personal Memorial Diamond. In case of low boron density, the diamond will be light blue or clear. The environment we use for the diamond growth prevents the incorporation of nitrogen atoms of the atmosphere into the diamond crystal lattice, which would result in a yellowish color of the memorial diamond.

Our top priority is the respectful treatment of the cremated remains in the process of cultivation of the memorial diamond. Obtaining the carbon from the cremated remains is the basis for the growth of the memorial diamond. Many steps of purification and graphitization are done between the ashes and the carbon extracted from it. Sometimes, in addition to the carbon, some very small trace elements of the cremains enter into the crystal lattice and appear in the diamond as inclusions. We regard this as a special proof and feature of the individual origin and the personal character of our unique memorial diamonds and not as a downside. The majority of Algordanza memorial diamonds have a quality level of VS1 or better. But we cannot guarantee a certain quality level due to the special origin of the carbon.

The age of the cremation ashes or hair is not relevant, rather the amount of carbon within, which does not diminish over time, ALGORDANZA has grown diamonds from ashes that are decades old.
