Memorial Diamonds from Ashes – A Lasting Tribute for Your Loved One

A memorial diamond is a real diamond created from the carbon in a loved one’s cremated ashes. Algordanza extracts the pure carbon and grows a unique diamond in our Swiss laboratory. The finished diamond is chemically, physically and optically identical to a natural diamond — and becomes a permanent, portable keepsake you can wear or keep close.

Why families in Hong Kong choose a memorial diamond. Hong Kong has limited burial space and many families want a meaningful, modern alternative to traditional niches or scattering. A memorial diamond lets you keep your loved one close wherever you are — at home, while travelling, or as a family heirloom for future generations.

Frequently asked questions

Is an Algordanza diamond a genuine diamond?

Yes – the Algordanza Memorial Diamond shows the same physical, chemical and optical properties as a dug diamond. We would not be allowed to use the expression “diamond” if we could not prove that the diamond is genuine.

Why do the diamonds have different colors?

The colour is white, but may have – depending on the individual quantity of the element Boron in the carbon – a blue tint. We do not manipulate the colour of the diamond in any way.

How long does it take to create a diamond?

The average production period is approximately 4-9 months, however, it is influenced by the size of the diamond being ordered and also the number of orders being processed at the time in Switzerland.
