LONITÉ™, Switzerland, turns human cremation ashes into diamonds. Cremation diamonds from ashes are made out of 200 g (8 oz) cremation ashes or 10 g human hair (0.4 oz) by using HPHT technology in the LONITÉ laboratory. These "cremation diamonds" or "memorial diamonds", derived from human ashes, are GIA and IGI certified diamonds out of ashes.
Our process of transforming cremation ashes into diamonds takes between 3 and 9 months(1 ct), depending on the size and colour of the cremation diamond ordered.

Yes. LONITÉ creates a High-Pressure High-Temperature (HPHT) environment, similar to the natural underground setting, in our laboratory, to turn human cremation ashes into diamonds.
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.
The starting point for a cremation diamond is 0.25 carats, which costs C$ .
It takes 6 months on average for the process of being turned into a cremation diamond to be completed.
At least 200 g / 8 oz cremated ashes or 10 g / 0.4 oz hair are required for a cremation diamond to be created.
To turn ashes into diamonds, below ashes amounts are required.
It takes an average of 6 months to turn human cremation ashes into a one carat certified cremation diamond. The actual time of each cremation diamond is dependent upon the size ordered (normally 3-18 months).
Optional GIA or IGI certification, jewelry setting, and laser inscription services are offered at extra cost where it takes an extra 1 or 2 months for each service chosen.
The price for a typical Naturally Amber™ cremation diamond, made from ashes, ranges between Amber 0.25 ct - Amber 2.0 ct price in USD $ - $.

The LONITÉ cremation diamonds price includes all of the necessary costs involved in transforming the cremation ashes into a diamond, including the cost of sending the ashes to Switzerland.
The actual cost of turning cremation ashes into a diamond is dependent on the SIZE and COLOUR required.
Our cremation ashes to diamond cost comprises both the purification cost and the diamond creation cost, and reflects both the technical processes, and the time, involved in turning human ashes into diamonds.
The price of cremation jewellery: either diamond pendant jewellery or ring cremation jewellery, depends not only on the cremation diamond used, but also on the shape, metal type and metal weight used to make the jewellery.
Our jewellery prices include all mounting and shipment costs.
You can either choose from our cremation ring and cremation pendant designs, or submit your own idea for a quotation for a bespoke piece of cremation jewellery.
The process of turning human ashes into diamonds is certified by the existence of documentation procedures and tracking logs, similar to the process followed in a crematorium.
Scientific reports and an examination of the ashes to diamond process is also available to inspect, compare and validate the trace elements and carbon isotopes inside a cremation diamond, to ensure that it complies with the ashes of a specific person.
Re-verification on the ashes to diamonds process by an independent research institute can be arranged if required and mutually agreed.
It is truly unique to carve memorial words onto the edge (the girdle) of a cremation diamond for remembrance.

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.
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.
1. Material examination and carbon analysis.
2. Remove unstable chemicals at Nano-scale.
3. 2000°C purification in a vacuum environment.
4. Carbon refinement to a 4N purify (99.99%).
5. HPHT crystallisation at 3000K and 60000Bar.
6. Diamond polishing and authentic certification.

LONITÉ Laboratory and Process: From Ashes to Cremation Diamonds
The company name ‘Lonité’ originates from ‘Longévité’, a word from the Swiss official languages, Swiss French, which translates to enjoy a long life.
With its headquarters located 25 minutes from downtown Zürich, Switzerland, the technological origins of LONITÉ cremation diamonds date back to the early 1950s.
We are committed to handling every single step of the cremation ashes to diamonds process solemnly, with the respect, discretion and empathy that it deserves.

The bigger the cremation diamond’s size, the longer the ashes to diamonds process takes. Bigger cremation diamonds take more time, thus cost more.
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.
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.
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 are real diamonds made from human cremation ashes. Firstly, the carbon of the cremation ashes is purified. Then, it is pressed into a cremation diamond with high pressure and high temperature (HPHT) machine.
Yes, cremation diamonds are real diamonds. They are chemically, physically, and optically the same as diamonds that have been mined from underground. Cremation diamonds are all certified to be genuine diamonds.

A cremation diamond price starts from C$ or £ . The cost depends on the size of diamond ordered. The larger the size, the higher the cost.
Cremation diamonds can be made from human ashes due to the fact that diamonds are pure carbon and human body contains 18% carbon. Laboratories re-create an underground High Pressure High Temperature (HPHT) environment to make a cremation diamond.
The cost of purifying the carbon of the ashes is fixed. The cost of growing the diamond is dependent on the size of the diamond ordered. The total price starts from C$ or £ .
3 steps are needed to turn cremated ashes into diamonds:
Step 1: Extract the carbon from the cremation ashes or hair.
Step 2: Purify the cremation ashes to 99.99% purity in the LONITÉ laboratory.
Step 3: Place the carbon inside a high pressure and high temperature (HPHT) machine to crystalise.
One of the reasons that cremation diamonds are so expensive, is because the creation of a cremation diamond is such a personalised process - each order is handled individually. The extreme laboratory environment that is required to make a cremation diamond is another; the machine used is huge, and the operational cost of running it is high. A final reason is the complex technical procedures involved - it takes several months to make a cremation diamond.
