Life Element: Carbon.

Carbon [C] accounts for 18% of the human body; diamonds are crystalized carbon. Memorial diamonds are genuine diamonds grown by using the carbon contained within hair or cremation ashes.

Nitrogen [N] accounts for 3% of the human body, which gives the diamond a Naturally Amber™ colour, varying from light yellow to deep orange.

Purely Colourless™ diamonds are created by removing nitrogen [N] from the carbon [C].


Re-create natural environments.

Natural diamond develops in an environment of extreme high-pressure and high-temperatures (HPHT) deep underground.

Similarly, precise creation and control of extremely high temperatures (3000K) and pressures (60000Bar) inside LONITÉ’s laboratory recreate this natural environment and turns carbon from hair or ashes into diamonds.


Technical Know-How

I. Carbon Purification.
5000 minutes for a 4N Purity (99.99%).

Purification takes approximately 5000 minutes per order.

Impurities are removed and reduced to 1/500 of the original impurity content, providing 4N purity (99.99%).

Every little detail matters. LONITÉ insists on utilising highly specialised state-of-the-art equipment, providing the greatest precision, quality and stability: surgical grade, accurate to 0.001(g).

18.2 MΩ.cm Ultrapure Water System.
Water is purified using this ultrapure water system to 18.2 MΩ.cm (1250 times better purity than drinking water). All chemical containers are cleaned with the ultrapure water to avoid introducing external contaminants.

II. Diamond Crystallisation.
Purely Colourless™ at 0.5-1.0 mg/hour.

The crystallisation foundation is assembled with the purified carbon. It’s so pure and dense that even air atoms are excluded, such as H₂O (water vapour) and O₂ (oxygen).

A typical Purely Colourless™ diamond grows slowly and steadily at 0.5-1.0 mg/hour (an extremely slow speed). The slower speed, the better stability and better crystal structure. A 1 carat diamond can take 750 hours to grow.

1MW Backup Power Generator.
Crystallisation takes several weeks. As power interruption or voltage instability, for just a few minutes, can have a drastic effect; similar to hospitals, backup power generators are always on standby.

Thermostat Temperature Controllers.
To keep the core temperature of the diamond chamber precisely at 2651.6°C [*], high-precision thermostat temperature controllers are used are used in our factory space. This ensures that the inside temperature remains constant that any external temperature changes will not have any effect.

Fluorescence and luminescence tracing are commonly used in diamond analysis under special environments such as short wave ultra-violet light. More extensive and advanced examination tools are used inside LONITÉ laboratory.

Atoms Tracing on Chemical Density.

Memorial diamonds look the same as a natural diamond, both optically and chemically.

However, experts at LONITÉ are able to differentiate genuine memorial diamonds scientifically and technically because there are slight differences in the carbon atoms and chemical density.

Certification of Origin with Analysis Report.

All LONITÉ memorial diamonds are accompanied with certification of origin and a process analysis report, determining and proving scientifically that a LONITÉ diamond originates from the ashes of the client’s loved one.

Verified by Independent Research Institutes.

The indicated analysis records, laboratory data, chemical and physical factors, can be re-verified and validated by any independent certification and quality control institute.

The carbon origin of your memorial diamond can be technically tracked and identified.
As of 2015, this exceptional technological breakthrough is brought to reality only by LONITÉ’s eminent research team.


Material Examination

The ashes or hair is first and foremost analysed to determine whether the ashes or hair contains enough carbon to be turned into a diamond. Because the carbon content of ashes differs from case to case, the total contained carbon may or may not be enough to successfully undergo LONITÉ’s diamond creation process. Thus, it is highly suggested to provide additional hair samples from the family as a supplement/backup plan.

Planetary Nano-Crystallisation

In a special solvent, impurity remover is applied to remove unstable chemicals. The material (ashes or hair) is then milled and stirred into a nano powder in a special chemical gas environment. The impurity remover attaches to impurities, which are then isolated from the materials by a high-speed centrifuge. Furthermore, special treatment and techniques are implemented so the remaining carbon is adequately preserved while other elements extracted are reduced to a fractional minimum.

Milling equipment similar to the movement of planetary systems, involving both rotation and revolution


Heated Vacuum Purification

The ashes or hair is heated to an extreme temperature to get rid of further volatile impurities. During the process, oxygen is removed and a certain inert gas mixed with protective reducing gas is injected to protect the ashes or hair from oxidation. Double handling is applied for chemical extraction. In some cases, high voltages may be applied via an energised airtight container to melt and evaporate chemicals in order to separate the solid carbon.

Wet Chemical Carbon Purification

The hair or ashes is then placed in a safe and resistant cabinet, in a wet chemical environment, to enhance purity by removing heavy metals. Automatic and program-controlled temperatures, stirring speed, and chemical reagents amount ensures the carbon quality. At the end of this final purification step, the carbon purity reaches as high as 99.99%. If the purity levels have not reached 99.99% by this stage extra, customised purification steps are implemented to remove the remaining impurities.

Purity is enhanced manually by chemical specialists

STEP 5 HPHT Crystallisation

High-Pressure High-Temperature (HPHT) presses where carbon atoms from hair/ashes are transformed into a genuine diamond

The extracted pure carbon is converted into flake graphite and formed into a cylinder shape. Before the pure carbon cylinder is put into the diamond synthesis machine, the graphite is carefully wrapped and prepared by protective and corbelled materials for the final technical steps that require functions such as pressure and temperature measurement, insulation and protection. The transformation takes several days to several months depending on the size and colour of the memorial diamond ordered.


Diamond Polishing

Unlike mined diamonds, rough memorial diamonds are usually mixed with graphite and other materials especially on the diamond’s surface. The rough diamond is carefully polished by experienced experts who deal solely with grown diamonds. A rough un-cut memorial diamond can be provided if requested. However, this rough diamond should NOT be cut at any time after it is delivered because inexperienced diamond cutters without specialised cutting skills are highly likely to break the diamond.
