LONITÉ's memorial diamonds

High quality and pure

Diamonds from ashes

Diamond burial in Germany is now possible thanks to LONITÉ, who produce memorial diamonds in Switzerland. These are made from human hair and the cremation ashes of the deceased, which are sent to Switzerland for the process of creating the diamond from ashes.

  1. Exclusively from elements of life
  2. No heavy metals - No artificial colors
  3. Production of natural diamonds, no CVD diamond coating

Memorial diamonds made from ashes or hair of the loved one

High quality and noble diamonds are made entirely of carbon. Since the human body also contains 18% carbon, the noble LONITÉ diamonds are made from the carbon found in hair, cremated bones or cremation ashes.

6 months on average

The diamonds that emerge from the Diamond Burial Germany are certified and genuine.

The only difference that exists between a natural diamond and that of a LONITÉ diamond burial is the origin: the carbon of the diamond from ashes is obtained from human cremation ashes, while the growth in nature takes place with the help of underground, carbon-like minerals.

From light yellow (left) to deep orange (right), each diamond has an individual color.

Grown naturally

A unique memory

Every diamond has grown naturally and is completely unique - just like the loved one during their lifetime, this diamond does not exist a second time.

The final shape, size and color depends entirely on the origin of the diamond and the composition of the carbon in the hair or ashes.

After hair and cremation ashes have been received by us in the laboratory for the diamond from ashes (Switzerland), they are cleaned and placed in a synthetic environment. Here they can grow into a diamond independently and without external influences.

This environment only provides a basis. The exact dimensions can neither be controlled nor predicted.

In this way, an irreplaceable and unique diamond is created that is absolutely extraordinary not only in its origin, but also in its appearance.

Sizes of a diamond

Diamonds are generally measured in carats (ct), a unit of mass.

One carat is equal to 0.2 g (200 mg; 0.007055 ounces).



[*] The size demonstrations may differ from the actual dimensions due to different screen resolutions.
The size of the memorial diamond is influenced by the given growth time.

Rough diamonds are not cut to preserve their natural appearance.

Cut of a diamond

Natural beauty

A diamond in the rough is a unique choice for those who prefer complete naturalness and want a "whole" diamond that has not been removed. Please note, however, that only cut diamonds have the famous 'brilliance'. In addition, the colors of rough diamonds can appear darker.

Rough diamonds (uncut / uncut) are available at a discount of 20% for sizes from 0.35 carats. A rough diamond for diamond burial in Germany is unfortunately not possible for 0.25 carats.

The right shape

You can choose from 10 different cuts for your very own memorial diamond.

The cuts differ mainly in their brilliance. In general, however, one can say: the more corners and cuts the diamond has, the higher its brilliance.

For this reason, the brilliant cut is, as its name suggests, the one with the highest brilliance and also our most popular cut.



You don't know which cut is the right one?

No problem! You can simply leave the cut option blank on the order form. The cut is then determined by our experts according to its final shape.

So you don't have to choose the shape, because the diamond does it all by itself.

In this way, as little as possible is cut from the diamond and a large part of its volume is preserved - a perfect diamond burial Germany.

Color variations of a diamond

7 unique colors for your diamond burial in Germany

Naturally grown diamonds are born with a number of different colors due to the diverse, underground environments.

Unfortunately, in our synthetic environment, we cannot make this wide range of colors possible for a diamond made from ash (Switzerland). However, we can create different colors as the memorial diamonds grow.

With the help of the body's own elements contained in the ashes, we can create 7 unique colors. Since the cost of production varies depending on the color, this also has an impact on the diamond burial costs.

The creation of the colors for a commemorative diamond

Natural Amber ™

The human body consists of 3% nitrogen 171, which gives the diamond its natural Amber ™ color.

Natural amber ™ is the color that is achieved in the standard process for Swiss diamonds from ashes - without adding or removing any other substances.

Each diamond has its own natural color (from light yellow to dark orange). No two color nuances are alike.

Purely Colorless ™

In order to grow a pure colorless ™ diamond, the nitrogen 171 has to be removed from the carbon [C] of the ashes.

This process is very complex and time-consuming, which also explains the higher diamond burial costs for pure colorless ™ diamonds.

But they convince with the highest carbon purity and the noblest appearance.

Additional colors

Apart from the two variants shown above, the other colors are achieved through different chemical or physical environments, as shown below.

Certificate of Authenticity

Memorial diamonds are real diamonds that can be certified by all globally recognized gemology institutes.

The proof for eternity: an independent proof

The certificates of authenticity for LONITÉ diamonds can be obtained from Gemological Institute of America (GIA) or International Gemological Institute (IGI), which prove that all LONITÉ diamonds are real diamonds and certify that they are artificially produced (not mined).

The origin of your memorial diamond is certified by the LONITÉ laboratory.

After the memorial diamond has completed its growth process, a third-party certification can be requested from the GIA or IGI to ensure the authenticity of your memorial diamond and, above all, to identify the diamond's origin - the LONITÉ laboratory.

The barcode is attached to the container for all intermediate steps. Tracking ID, name and dates are logged in accordance with our Standard Operating Procedures (SOP) - LNT OT95000: 2010.

Always by your side

We understand your worries and fears and we know that it is not easy for you to let go of your loved one.

I. Maximum use of ashes / hair

Up to 99.99%.

It would be wrong to say that "a memorial diamond is made from 100% ashes" ✘.

For a diamond burial in Germany, a microscopic diamond is always required as a seed crystal from which the memorial diamond can develop.

However, LONITÉ is able to produce memorial diamonds that are made up of up to 99.99% of the carbon from human ashes or hair.

II. Natural diamond seed

No artificial CVDs

A Diamond seeds is a microscopic diamond that serves as the basis for the memory diamond that grows from it (seed crystal). The carbon atoms (from the ashes / hair) then attach themselves to it under enormous pressure and begin to crystallize.

As diamond seeds, LONITÉ only uses the best 0.1% single-crystal natural diamonds instead of CVD (Chemical Vapor Deposition) diamonds.

III. A special type of diamond: IIb

Valuable and unique

The LONITÉ diamonds in blue and pure colorless ™ are Type IIb diamonds.

You can recognize them by the following procedure: When examined with an infrared spectrometer, these diamonds show a remarkable absorption of the red color of the visible spectrum.

This type of diamond occurs in nature only 0.1% and is therefore very rare and valuable. LONITÉ's type IIb diamonds are visually indistinguishable from the natural variant.

And best of all: The type IIb commemorative diamonds have a much more valuable origin than the natural diamonds of this type - because they come from your loved ones.

IV. No heavy metals (0.00%)

100% sure

LONITÉ diamonds are free from lead (Pb), mercury (Hg), bismuth (Bi) and sodium bromide (NaBr).

LONITÉ also uses natural and medically safe agents to clean the ashes.

No heavy metals (0.00%) are used in the entire LONITÉ production process.

V. No artificial colors (0.00%)

Natural colors only

LONITÉ creates colored diamonds from ashes by providing you with a special growth environment instead of mixing artificial dyes on the diamonds.

The artificial environment only provides a basis for the coloring. The final color then depends on the composition of the substances in the ash.

Each diamond from ashes (Switzerland) has a unique color that emerges from the ashes. No two diamonds are alike.

VI. Absolute purity (4N)

The essential 99.99%

The production of diamonds from ashes via the high pressure high temperature (HPHT) diamond synthesis can only be effectively achieved with the purest forms of carbon. All other trace elements must be removed.

Therefore, the ashes must be cleaned, because impurities lead to diamond defects and can split the diamond crystal.

Carbon is the basic element of life that occurs in every body. In order to avoid any defects, the purity of the carbon in the LONITÉ diamonds is at least 99.99%.

VII. 18% and 3% of the human body

Positive life elements

Carbon [C] occurs in the human body in a proportion of 18%; Nitrogen 171 is 3%. Both are important building blocks for proteins (with amino acids) and DNA. Without carbon [C] and nitrogen 171 life would not exist.

The carbon purification system leaves either nitrogen or boron (related to the metabolism of calcium) as a base for growth, creating either an amber or a blue color.

The diamond, however, becomes Pure Colorless ™ if only the carbon is retained and all other elements are removed.

✔ GIA certified real diamond
✔ HPHT diamond
(High pressure high temperature)
✔ New diamond made exclusively from ashes
✘ Imitation diamonds: moissanite or zircon
✘ CVD diamonds (Chemical Vapor Deposition)
✘ Off-the-shelf diamond injected with ashes

✔ LONITÉ IS a GIA certified real diamond.

A LONITÉ memorial diamond is physically, chemically and optically the same as a naturally mined diamond.

LONITÉ's real diamonds have a refractive index of 2.419 and therefore the same as all other naturally extracted diamonds.

✘ NO diamond imitation: jewel, crystal, zircon.

An "imitation diamond" is a fake diamond that is not made with carbon. Zircon (ZrSiO4) is a mass product for fashion jewelry and clothing accessories.

A fake diamond has a refractive index higher or lower than 2.419, which means that both brilliance and brightness are very different from a real diamond.

✔ LONITÉ is an HPHT diamond.
(High pressure high temperature)

The carbon source of LONITÉ's HPHT diamonds is pure carbon powder from ash (in a solid state).

The high-pressure, high-temperature process is based on the same principles as the natural production of diamonds and takes several months.

✘ NO CVD diamond
(Chemical Vapor Deposition)

The carbon source of CVD diamonds is a hydrocarbon gas such as methane.

The ongoing process only takes a few hours, but uses many, many cubic meters of additive gas to provide the necessary carbon.

✔ LONITÉ is a newborn diamond that is transformed from ashes.

Your memorial diamond made from ashes or hair is a completely new diamond that has been artificially grown

The required diamond seed is only 0.01%. 99.99% of the diamond grows from vital elements of the hair or cremation ashes.

✘ NO existing diamond with ash being injected through a hole.

Some "diamond burials" in Germany are nothing more than drilling open an existing diamond and then inserting a tiny amount of cremation ashes into it.

Heavy metals such as lead (Pb) and bismuth (Bi) are used in this procedure for "diamond burial".

Pour les diamants commémoratifs, les couleurs ambrées et dorées sont les options les plus basiques. Ces diamants sont produits selon une procédure simple, sans ajouts de microéléments ni de traitements techniques spéciaux. Les coûts et les durées de production des diamants commémoratifs ambrés / dorés sont les plus réduits, ce qui fait que ce sont les plus popular. La color ambrée / dorée résulte naturellement de l'azote qui reste dans le carbone et qui est essentiel dans les corps humains composés de protéines et d’ADN.

Le diamant commémoratif vert / jaune a besoin d'un cycle de traitement HPHT supplémentaire afin de modifier la structure cristalline ainsi que les centers colorés du diamant. En conséquence, la couleur verte / jaune nécessite un temps de fabrication plus long et a un prix relativement plus élevé.

Les diamants commémoratifs rouges obtiennent leur belle couleur en utilisant le même procédé qu’avec les diamants ambrés / dorés, mais avec un processus plus approfondi. En appliquant une lumière d'électrons à haute énergie avec un émetteur électronique, des centres colorés libre d'azote se formeront à l'intérieur du diamant ce qui donnera au diamant sa color rouge.

Le diamond commémoratif bleu parait majestueux et paisible. LONITÉ possède une technologie de pointe permettant de déterminer la densité d'atomes présente à l'intérieur des diamants commémoratifs. Ainsi, the color of diamonds bleus LONITÉ est très equilibrée.La croissance du cristal est plus rapide et plus facile lors de l'introduction d'atomes de bore à l'intérieur du carbone, ce qui fait que non seulement la production est plus rapide mais aussi que le coût est plus bas par rapport aux diamants commemoratifs incolores.

Le diamant commémoratif incolore est caractérisé par la pureté carbonique la plus élevée et ne présente aucun autres éléments ni impuretés. De plus, la procédure de production d’un diamond blanc pur est la plus technique et la plus onéreuse car sa production requiert plus de temps.
