Cremation ashes to diamonds

Also known as ash diamonds, an Algordanza cremation diamond is grown from the cremation ashes of a human. The cremated remains 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.

Memorial diamonds from hair

Memorial diamonds are created from hair the same way cremation diamonds are made from ashes. Many individuals desire a memorial diamond because they want a traditional burial and still have a unique keepsake of a lost loved one.

Algordanza guarantees the quality of every diamond created from ashes and hair as well as guarantees that your cremation diamond is made of 100% of the cremated remains of your loved one.

Diamond cost and selection

ALGORDANZA memorial diamonds are created as unique rough diamonds, just as nature would form them. Choose between a hair diamond or cremation diamond. Then choose the desired size and the right cut for the diamond, this decision should reflect your loved one’s personality.

An expert gemcutter will cut the memorial diamonds for you by hand. We offer six cuts: Brilliant, Emerald, Asscher, Princess, Radiant and Heart.

The cost of a memorial diamond is usually not higher than the expected costs associated with a traditional burial with the associated grave maintenance. ALGORDANZA memorial diamonds start at £ 2,040 for a medium size 0.30 carat diamond.

The process which ALGORDANZA used to create diamonds from cremated remains is officially notarized by a Swiss notary public.

The memorial diamond: 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 diamond funeral a beautiful and practical alternative.

The memorial diamond is an incredibly valuable keepsake for the bereaved, which is privately kept or openly displayed. It can be kept in the diamond box alongside a portrait photograph at home, or discreetly set in a ring or pendant so that you can always carry and honor your loved one with dignity.

Your memorial diamond is an enduring and discreet heirloom that will stay with your family for generations to come.

Creating a diamond from ashes or hair - This is how 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.

In order to be able to grow a diamond from ashes or hair, we need 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 and later transform into a diamond. To do this, we must simulate the extreme pressure and high temperatures that are also necessary for the natural formation of diamonds within the earth.

Each diamond is unique and therefore as singular as the loved one from which it was created.

I researched a number of memorial diamond companies before choosing Algordanza. It’s clear to me that they are the industry leader. What attracted me to them originally was the transparency of their process, but my dealings with Algordanza confirmed that I was making the right choice. Algordanza talked me through the process without a hard sell approach. All very patient, informative and understanding during a very upsetting time. When I decided to go ahead a personal meeting was quickly set up to collect my Dad’s ashes. Throughout the process I received regular updates.

I could not be more impressed with the finished product. I had an interest in precious stones prior to this process and the colour saturation, cut and clarity of the diamond is breathtaking. My stone is absolutely beautiful and has some unique characteristics that no one expected. I would not hesitate to recommend Algordanza, and I will cherish my diamond forever.

I cannot recommend Algordanza highly enough! Without a doubt the very best customer service I have ever received. Better still, the memorial diamonds we had made are absolutely beautiful! They took the time to explain the whole process and answer all of our questions in superb detail. Hoping for two diamonds of a very specific size, wanting to safely hand deliver the ashes in person, all on a very tight schedule in time for our wedding – we knew we were asking a lot! But Algordanza's team bent over backwards to make this happen.

Frequently Asked Questions and Answers

Like any high quality lab grown diamond, an ALGORDANZA™ diamond has the same physical, chemical and optical properties as a natural diamond. In our Swiss lab located in Domat/Ems, Switzerland we recreate the natural formation conditions so that your individual ALGORDANZA™ diamond can grow from the cremated remains or hair of a lost loved one.

ALGORDANZA™ memorial diamonds receive a 10 on Mohs scale of mineral hardness and conform to ISO International Standard 18323 (2015); memorial diamonds grown at ALGORDANZA™ are “laboratory grown diamonds”.

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 made 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. Don’t know how much of each you can acquire?
Contact us for help, we will help you to find out.

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.
