Company Story


Swiss Origin

The company name ‘Lonité’ originates from ‘Longévité’ in Swiss French, which translates to enjoy a long life. Diamonds after death is one aspect of this idea.

LONITÉ is a trademark of LONITE AG, Switzerland. LONITE AG’s research laboratory is a world leader in cremation diamond technology. LONITÉ’s story began in a small town near the Alps, 25 minutes' train ride south of Zürich, Switzerland, where they began asking if you can turn ashes into diamonds.


The technological beginnings of LONITE AG dates back to the early 1950s, when scientists learned you can turn ashes into diamonds using High-Pressure High-Temperature anvils.

The founders of LONITÉ are all leaders in the diverse fields of expertise required to turn cremation ashes into diamonds . They have years of experience in the jewellery trade, the funeral business, conducting scientific research, and creating beautiful diamonds. Together they have the blend of skills required in making cremation diamonds out of ashes.

At first only very small amber and blue diamonds could be created. Today, advancements in the technology of making diamonds out of ashes have changed all that. Now, cremation diamonds from ashes are available through LONITÉ in larger sizes and more beautiful colour. Your memorial diamond can reflect the loved ones personality and charm so that becoming a diamond after death continues their presence in your life. LONITÉ can, on your request, design a jewelry setting around your unique cremation diamond which will help you to keep it close to you.

Lonité headquarters are located in the beautiful and dynamic city centre of Zurich, Switzerland
