A Brilliant Memorial for Your Furry Friend


​Memorial Diamonds For Pets

The Science Behind Making Everlasting Memories

Each order is unique. So is our process to turn your beloved pet into a diamond. Our HPHT machines can process only one order at a time, contrary to the CVD method that is able to mass produce lab-grown diamonds and therefore can contain many diamond seeds at a time in the core of the machine. This is one of the reasons why one memorial diamond for pets can take between 5 to 18 months to make from start to finish, logistics and delivery included. The exact duration will also depend on the selected diamond’s characteristics, some lab-grown diamond colours requiring more technical efforts than some others. 

The Science Behind Making Everlasting Memories

Are memorial diamonds real? Can pet ashes or fur be turned into a sparkling diamond? 

Yes, memorial diamonds are real diamonds and yes, it is possible to turn the remains of your pets into a brilliant diamond. LONITÉ™ recreates and simulates in its state of the art laboratory the natural underground conditions a diamond needs to grow, thanks to its technology HPHT (high pressure, high temperature).
