What is a Memorial Diamond?

A memorial diamond (i.e. burial diamond, cremation diamond, memorial gem, memory diamond) is a diamond created from the carbon extracted from cremated ashes, hair or a combination of ashes and hair.

It’s a unique way to immortalize the memory of a loved one that’s passed and establish a family heirloom to be treasured for generations.

Creating a Memorial Diamond

Memorial diamonds are real diamonds with the same optical, chemical, and physical properties as natural diamonds. Using a controlled process revolves around extraction and compression of carbon, it replicates the natural geologic process that forms diamonds deep in the earth.

Algordanza’s process is unique in that we allow the natural colour of your loved one’s ashes to come through - with no other additives from foreign sources.
