FAQ on Diamonds from Cremation Ashes

How long does the cremation ashes to diamonds process take?

Including the time involved for shipment and purification, the total time of turning human ashes into diamonds takes between 3 and 9 months, depending on the colour and diamond size required.

How does carat size affect the diamond growing time?

The bigger the cremation diamond’s size, the longer the ashes to diamonds process takes. Bigger cremation diamonds take more time, thus cost more.

Why does colour affect the ashes to diamonds processing time?

Different colours require different procedures in different synthesis environments, so the growing speed of the diamond will be different. Amber is the most natural colour, and a cremation diamond of this colour undergoes the basic process, which takes the shortest time: 35-70 days. In contrast, our Purely Colourless™ cremation diamond, with 4N purity (99.99%) of carbon, uses the most sophisticated technology and has the longest growing period: 60-120 days, depending on carat size.

How can I prove that the cremation diamond is from hair/ashes of my loved one?

Our proof comes in the form of a technical examination and the certification methodology of the cremation diamond’s original source. Scientific proof and certification can be provided based on the carbon atoms and chemical density of the cremation diamond, which must match the carbon, hair or ashes that the diamond originated from.

The carbon is tracked and documented continuously throughout the ashes to diamonds process, by a LONITÉ team of microphysics and high pressure science researchers.

Why is the cost of turning cremated ashes into diamonds so high?

The cost of a cremation diamond is dependent on the SIZE and COLOUR required. A bigger diamond requires a longer growing cycle, thus generates a higher cost.

The machine used is huge. The inside temperature and pressure are ultra-high. Extreme precision is required. A one carat colourless diamond can take hundreds of hours to grow.

As a result, the technology used to turn ashes into diamonds is complicated and very costly.
