Company Story

About LONITE AG - Ashes to diamond

Swiss Origin

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

LONITÉ is the trademark under LONITE AG, Switzerland. LONITE AG’s research laboratory is a world leader specialising in the technology to turn ashes into close heart diamonds for you to keep long lasting memories of your love ones in UK. LONITÉ’s story began in a small town near the Alps, 25 minutes' train ride south of Zürich, Switzerland.


The technology base of LONITE AG dates back to the early 1950s, when scientists created the first man-made diamonds using High-Pressure High-Temperature anvils.

The founders of LONITÉ are all leaders in their field of expertise required to turn cremation ashes into diamonds. For years our founders have been involved in the cremation jewellery trade, scientific research to update the process to make diamond out of ashes, the funeral business, as well as turning your loved one cremation ashes or hair in UK into beautiful memorial diamonds.

At the very beginning only very small amber and blue memorial diamonds could be created. Today’s advancements in technology have changed all that, meaning cremation diamonds from LONITÉ come in larger sizes and more beautiful colours.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 located 25 minutes from downtown Zürich, Switzerland.
