Yes. LONITÉ™ creates a High-Pressure and a High-Temperature (HPHT) environment, similar to the natural underground setting, in our laboratory, to turn human cremation ashes into diamonds. One cremation diamond can take between 3 to 9 months (1 ct) to make from the order procedure until the delivery to the client. The duration will depend on the ashes into diamonds’ caracteristics selected.
The human body contains 18% carbon, whilst diamonds are pure carbon.
Cremation diamonds are real diamonds, made from love ones' cremated ashes or hair, that can be graded the same to natural diamonds.
The only difference between natural diamonds and cremation diamonds from ashes is their origin - cremation diamonds are created from cremated ashes, whereas natural diamonds are minerals that form underground over billions of years.
Mothers, husbands and daughters can wear memorial diamonds as a way of keeping their loved ones with them.
Cremation diamonds are usually set into a piece of memorial jewellery, such as a cremation ring, pendant or pair of earrings, and the wearer can take comfort in the fact that they will always have their loved one with them.
Cremation Diamonds can be certified by GIA and IGI.

Diamonds are pure carbon crystals.
Carbon [C] accounts for 18% of the human body; Nitrogen [N] for 3%.
Memorial diamonds (or cremation diamonds) are genuine diamonds grown from the carbon and nitrogen of human ashes, hair, or cremated remains.
Natural diamonds are created in an underground environment of extreme high-pressure and high-temperature (HPHT).
The LONITÉ laboratory recreates a similar environment at 3000K (temperature) and 60000Bar (pressure), which transforms carbon from hair or cremation ashes into diamonds.
To start the process, carbon is extracted from the cremated remains, then purified. This material goes through diamond making machines, which transforms the carbon into real diamonds.

Top 3 Most Asked Questions
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, the cut and the cremation diamond size required.
You must provide at least 200g of ashes or 10g of hair which are the normal amounts required to grow a cremation diamond. However, if you do not have enough cremation ashes or hair, family members can provide a supplement amount of hair that will be added to the ashes or hair already provided.
The cost of cremation diamonds may vary according to the color, the size and the cut selected like it does for natural diamonds as well. Price starts from $1,400 or £1,400. Please, refer to our cremation diamonds pricing list for more information.
Creating a Cremation Diamond from Ashes
To turn ashes or hair into diamonds, we first need to extract the carbon contained in the ashes of hair provided. The ashes are placed in a specialized crucible which is heated to over 5000F to make sure every element except carbon oxidizes, and then temperature is raised further so that the carbon can become graphite. The graphite with a metal catalyst and a diamond seed crystal are then placed into the core which goes into a specialized diamond press capable of creating extreme tension which then starts working, thus bringing the pressure to about 800,000 pounds/square inches. During the last stretch when the press is working, the temperature in the room stays about 2500F until the cremation diamond is formed.
The bigger the cremation diamond's size is, the longer the ashes to diamonds process takes. Bigger cremation diamonds take more time, thus cost more. Purely Colorless Cremation Diamonds also takes the longest to grow as it requires us more technical efforts.
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.
If you want to create several cremation diamonds from one individual, it is possible, and you will simply have to provide us with more ashes or hair than the basic amount required of 200g of ashes or 10g of hair.
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.
Cremation Diamonds Quality
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.
