2. What Is A Memorial Diamond?


A memorial diamond, also called a cremation diamond, is a unique and personal gemstone made from the carbon extracted from a loved one’s cremated ashes. 

This remarkable process mirrors the natural conditions that form diamonds over millions of years, transforming cremated ashes into a diamond, which is a lasting symbol of love and remembrance.


Here’s a quick overview of the steps involved in creating a memorial diamond:


  • Collection of Carbon: The first step is to gather the cremated ashes or hair from the loved one who passed away. This carbon is what forms the foundation of the diamond.

  • Extraction and Purification: The carbon content from the ashes is extracted, purified, and then prepared for the diamond synthesis process.

  • Diamond Formation: Using high-pressure, high-temperature conditions similar to those found deep within the Earth, the carbon is transformed into a diamond.

  • Cutting and Polishing: After the diamond is formed, it’s cut and polished to bring out its brilliance, just like any other diamond.


These memorial diamonds are far more than just stones; they are a tangible connection, holding the spirit of a loved one in the most beautiful, eternal way. It’s a keepsake that allows their memory to shine, forever carried with you.

3. How Much Ashes Are Needed To Make A Memorial Diamond?


When creating a memorial diamond from cremated ashes, the amount of ashes required depends on the size of the diamond a client wishes to create. Generally, the following quantities of ashes are sufficient for producing up to three LONITE cremation diamonds:


  • Cremated ashes: Approximately 5 oz (150 g)

  • Cremated bones: Around 7 oz (200 g)

  • Hair: As little as 0.2 oz (5 g)


If customers require a large number of diamonds or larger stones, more ashes are needed. In some cases, clients combine different carbon sources, such as adding a small amount of hair (0.2 oz or 5 g) to supplement the ashes to ensure enough carbon for the diamond creation.


The carbon content in cremation ashes varies from individual to individual. To avoid any potential issues, many clients provide a bit of extra hair (around 5 grams) as a backup, to ensure there’s enough material to form a cremation diamond. It’s important to note that the process is irreversible, so any extra material is safely handled with care.

  1. Certifications: 


Many clients choose to have their memorial diamond certified, ensuring the authenticity and quality of the diamond.
