Ashes into cremation 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.

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 Kevin confirmed that I was making the right choice. Kevin talked me through the process without a hard sell approach. He was patient, informative and understanding during a very upsetting time. When I decided to go ahead he quickly set up an in person meeting 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 even Kevin didn’t expect. I would not hesitate to recommend both Algordanza and Kevin. 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! Kevin was amazing. He 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 Kevin and his team at Algordanza bent over backwards to make this happen.

After researching ashes to diamonds UK online, I determined that Algordanza Cremation Diamonds was the best and most reputable company in the business. I contacted Kevin Foy at Algordanza UK near London, we met up and I quickly decided to go ahead."

Frequently Asked Questions and Answers

Like any high quality lab grown diamond, ALGORDANZA™ diamonds have 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.

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.
