How much ash is in a 1 carat diamond?

Published in Memorial Diamond Creation 2 mins read

While cremated ashes are not literally contained within a 1 carat diamond, a minimum of 500 grams of cremated ashes is typically required as raw material to create a memorial diamond of up to 1-2 carats. The diamond itself is pure carbon, synthesized from the carbon extracted from the ashes.

Understanding Memorial Diamonds and Ash Requirements

Memorial diamonds offer a unique way to honor a loved one by transforming a small portion of their cremated remains into a genuine diamond. This process replicates the natural diamond formation that occurs deep within the Earth.

The Transformation Process

The creation of a memorial diamond involves sophisticated technology that extracts carbon from cremated ashes. This carbon, which is an elemental component of all living beings, is then subjected to extreme high-pressure, high-temperature (HPHT) conditions within a laboratory. Over several months, these conditions cause the carbon atoms to crystallize into a rough diamond.

Ash Quantity for Diamond Creation

The amount of cremated ashes required is substantial because only a small percentage of the ashes is pure carbon suitable for diamond synthesis. The remaining inorganic materials are removed during the processing.

Here's a breakdown of the typical ash quantity needed for memorial diamonds:

Diamond Size (Carats) Minimum Ash Required (Grams)
Up to 1-2 carats 500
Other sizes Varies, usually more for larger diamonds

Key considerations for the ashes:

  • Carbon Source: The diamond's brilliance and hardness come from its pure carbon structure. The carbon used is meticulously extracted from the ashes.
  • Storage: The ashes are typically required to be submitted in airtight bags to preserve their integrity and prevent contamination.
  • Purity: The purity of the carbon extracted is crucial for the diamond's quality. Advanced purification steps ensure that the final diamond is composed of pure carbon atoms.
  • Unused Ashes: Any cremated ash material not used in the diamond creation process is typically returned to the family.

In essence, while a 1 carat diamond (weighing 0.2 grams) is a compact, pure carbon crystal, it requires a significant initial quantity of ashes to yield the necessary carbon for its formation.
