Swiss Origin

Our Story

​LONITÉ’s story began in a small town near the Alps, 25 minutes train ride south of Zürich, Switzerland, where the company's founders started to ask if you can turn ashes into diamonds.

The company name ‘Lonité’ originates from ‘Longévité’ in Swiss French, translating to last in time. Diamonds after death are one aspect of this idea.

LONITÉ is a trademark of our Swiss company LONITE AG. LONITE AG with its laboratories and scientists is a world leader in cremation diamond technology.


What Sets Us Apart

The roots of LONITE AG's technological journey trace back to the early 1950s, an era when visionary scientists uncovered the art of transforming carbon into diamonds using High-Pressure High-Temperature anvils.

At the heart of LONITÉ, our founders emerge as trailblazers in a range of fields essential for crafting memorial diamonds and delivering impeccable services. Drawing from extensive backgrounds in jewelry craftsmanship, the funeral industry, scientific exploration, and diamond artistry, they unite their diverse expertise. Together, they possess the ideal blend of skills necessary to create exquisite cremation diamonds from ashes, offering solace to families in their times of need.


Identification specifics are marked on tracking tags throughout the process.


Improved New Standards

LONITÉ’s improved Standard Operating Procedures (SOP LNT OT95000) were introduced to provide the highest level of control and monitoring. Our internal documentation and management systems keep track of each individual order are improved and refined to create the greatest possible reliability when growing diamonds from cremated remains.


25 Checks at 7 Inspection points

Human hair/ashes or pet fur/ashes are marked with a unique tracking ID and bar code upon arrival. There are seven vital inspection points along the diamond growing process, with a total of 25 checks performed by our trained staff in the different departments. Staff IDs and access dates are logged at every step of the way. All processes are traced. Photos are taken so that you can personally see the care and attention to detail we use in converting your loved ones’ remains into a beautiful cremation diamond you can treasure forever.


Medical-grade, Accurate to 0.001(g)

At the start of the process, hair or cremation ashes of your loved one are carefully and respectfully cleaned with medical-grade sterilization alcohol. The precisely measured amounts of chemical purification agents and catalyst are accurate to three decimal places (0.001g). The Standard Operating Procedures (SOPs) are necessary to increase the cremation diamond’s color, purity, stability and quality.

Tracking ID, name and bar code are attached to containers throughout the process of making diamonds out of ashes. At each transfer or relocation, the information is double checked by staff from both the sending and the receiving departments.
