Life crystal of bone ash, production of bone ash crystal



Application of sigma electric furnace in high temperature heat treatment technology in preparation of diamond from ashes



Life Element: Carbon.


Turning cremation ashes into diamonds is possible because Carbon [C] accounts for 18% of the human body and diamonds are crystallized carbon. Cremation diamonds are genuine diamonds grown by using the carbon contained within hair or cremation ashes.

The following is the introduction of the British neconnected crystal stone manufacturer


The graphite with a metal catalyst and a diamond seed crystal are placed into the core. The core 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.


The process of turning human ashes into diamonds takes about 6 to 9 months. During the last stretch when the press is working, the temperature in the room stays about 2500F so that the ashes turned diamonds become solid. This process results in rough crystals that are cut and polished into memorial diamonds. The color of the finished ashes into diamond ranges from white to dark blue, depending on the boron content of the ashes of the deceased.

The color of the ashes into diamond: The Naturally amber color of cremation diamonds comes from the life element Nitrogen that makes up 3% of the human body whereas the color blue comes from the boron content. Purely Colorless diamonds are created by removing nitrogen and boron from the carbon prior to making a memorial diamond from the ashes.


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

氮[N]占人体的3%,这使火葬钻石具有天然的琥珀色 颜色,从浅黄色到深橙色不等。

Purely Colourless diamonds are created by removing nitrogen [N] from the carbon [C] prior to making a cremation diamond from the ashes.

STEP 1 *步

Material Examination


The hair or cremated ashes are first analysed to determine whether they contain enough carbon to be turned into a diamond. The carbon content of ashes differs from case to case, and the total contained carbon may or may not be enough for LONITÉ’s diamond creation process. It is highly suggested that clients provide additional hair samples from the family as a supplement/backup plan.

STEP 2 第2步

Planetary Nano-Crystallisation


Impurity remover is applied in a special solvent 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.

STEP 3 第3步

Heated Vacuum Purification


The milled, purified material is heated to extreme temperatures to eliminate volatile impurities. At this step oxygen is removed and inert, protective and reducing gases are injected to protect the ashes or hair from oxidation. Double handling is applied for chemical extraction. In some cases, high voltages may be applied in an energised airtight container to melt and evaporate chemicals, further purifying the solid carbon.

STEP 4 第4步

Wet Chemical Carbon Purification


The carbon from hair or ashes is then placed in a safe and resistant cabinet, a wet chemical environment so as to increase purity by removing heavy metals. The program-controlled process of specific temperatures, stirring speeds, and the addition of chemical reagents ensures the carbon quality. At the end of this final purification step, the carbon purity reaches as high as 99.99% (4N Purity). If the purity levels have not reached 99.99% by this stage, additional customised purification steps are implemented to remove the specific remaining impurities.

Crystallisation 第5步HPHT结晶

High-Pressure High-Temperature (HPHT) presses transform purified carbon atoms from hair/ashes into genuine diamonds


The purified, extracted carbon is converted into flake graphite in form of a cylinder. Before being placed into the diamond synthesis machine, the cylinder is carefully wrapped in protective and corbelled materials. This prepares it for the final technical steps that require pressure and temperature measurement, insulation and protection. The transformation takes several days to several months depending on the size and color of the memorial diamond to be created.


STEP 6第6步

Diamond Polishing


Unlike mined diamonds, rough memorial or cremation diamonds are usually mixed with graphite and other materials, paticuliarly on the surface. The rough diamond is carefully polished by experts who deal solely with grown diamonds. A rough un-cut memorial diamond can be provided on request for as long as there is no attempt to cut it after it has been delivered because inexperienced diamond cutters are very likely to break the diamond. 




Technical Know-How 技术

I. Carbon Purification.


Cremated remains are purified for 5,000 minutes, over 3 days, to achieve 99.99% carbon, (4N or “4 Nines” purity).

火化的遗体经过3天净化5000分钟,达到99.99%的碳含量(4N或“4 9”纯度)。

Purification takes approximately 5,000 minutes, over 83 hours, for each memorial diamond ordered.


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


Every little detail matters when turning ashes into diamonds. LONITÉ uses highly specialized state-of-the-art equipment that allows the greatest precision, quality and stability. Instruments are surgical grade, scales are accurate to 0.001(g).


18.2 MΩ.cm Ultrapure Water System.

18.2 MΩ.cm超纯水系统。

Water is purified using a ultrapure water system to 18.2 MΩ.cm (1,250 times more pure than drinking water). All chemical containers are cleaned with the ultrapure water to avoid introducing external contaminants to the cremated ashes.

使用超纯水系统将水净化至18.2 MΩ.cm(比饮用水纯净1250倍)。所有的化学容器都用超纯水清洗,以避免外来污染物进入火化的灰烬。

II. Diamond Crystallisation.


Purely Colourless at 0.5-1.0 mg/hour.

纯无色 0.5-1.0毫克/小时。

The purified carbon is the foundation for cremation diamond crystallisation. Air, along with other atoms such as H₂O (water) and O₂ (Oxygen) are removed to ensure that the carbon is very pure and dense.


A typical Purely Colourless diamond grows slowly and steadily at the extremely slow speed of 0.5-1.0 mg/hour. Slow crystallization results to fewer flaws and better structure in the cremation diamond. This means a 1 carat diamond can take 750 hours, almost a full month to grow.


1MW Backup Power Generator.


A Cremation diamond takes several weeks to grow and a power interruption or voltage instability, even for just a few minutes can have a drastic effect. To avoid such shortcomings, LONITÉ has backup power generators on standby at all times.


Thermostat Temperature Controllers.


uses high-precision thermostat temperature controllers to keep the core temperature of the diamond chamber precisely at 2651.6°C [*]. This ensures that the inside temperature remains constant and unaffected by any external temperature changes.
