Diamonds from ashes or hair by ALGORDANZA™ UK / Ireland

Remembrance of a lost loved one

Diamonds made from cremation ashes

Also known as ash diamonds, an Algordanza cremation diamond is grown from the cremation ashes or hair of a human. The ashes are first put through a special process to extract pure carbon, then using special HPHT presses and Swiss precision, your loved one is turned into a diamond.

Ashes to diamonds guarantee

Algordanza is the only memorial diamond company who guarantees that your personal diamond is made of 100% of your loved one’s ashes or hair. We do not add generic carbon, nor do we artificially colour any diamonds from ashes or hair.

Ashes to diamonds cost

The cost of a memorial diamond is usually not higher than the cost of a traditional burial with the associated grave maintenance and starts at £1,995 for a 0.30 carat diamond.

Blue and colourless diamonds are the most difficult and time consuming diamonds to grow, ALGORDANZA specializes in these very rare and precious gems.

Note: We do not offer an order kit or welcome kit, which gives one a feeling of obligation after paying the starter kit’s initial price.

An heirloom for eternity

Compared to traditional types of funerals, the cremation diamond represents a very personal type of mourning, remembrance and joy. Especially in times of increasing mobility in our society and subsequent distance to the family, grave maintenance can be difficult, which makes the creation of a memorial diamond(s) a beautiful and practical alternative.

The memorial diamond can be kept in it’s box alongside a photograph at home, or discreetly set in a ring or pendant so that you can always keep your loved one close.

How Algordanza memorial diamonds are made

The ALGORDANZA manufacturing process in Switzerland produces blue, synthetic diamonds that have the same physical and chemical properties as diamonds that are created in nature.

ALGORDANZA needs at least 500g of cremation ashes or at least 5g of hair. From the ashes or hair we extract the carbon, which we then convert into graphite allowing us to grow a raw diamond or multiple diamonds using a real diamond seed. With special HPHT machines, we create the extreme pressure and high temperatures which are needed for natural diamond formation within the earth.

It is not the volume of ash that is decisive for the growth of a cremation diamond, but its carbon content. A cremation diamond is grown from the carbon extracted from human ashes of which a minimum of 500g is needed to grow, this is because ashes contain approximately 20% carbon.

If a company that turns ashes into diamonds needs less than 500g of ashes, they are more than likely adding industrial carbon (impurities) to the process in order to create the carat size of diamond needed, Algordanza guarantees that your cremation diamond is created from 100% of the cremation ashes sent to us.

Since hair contains approximately 51% carbon a much smaller amount of hair can be made into a diamond or diamonds.

If you choose a memorial diamond, then a minimum of 5g of hair is needed, or a combination of hair and ashes.

We document our rigorous quality control with an ALGORDANZA certificate. We guarantee authenticity, weight, cut, colour and the origin of the diamond having been created from the delivered cremation ashes or hair.

Each diamond order is marked with a unique reference number. (This reference number will be provided to you when you sign the order form) Consequently, we are able to retrace every step of the process; starting from the order to the finalized diamond. Throughout the process, we provide information on the status of the transformation as each stage completes.
