How Ashes Become
a Memorial Diamond
A memorial diamond is a real diamond created from the carbon within ashes, hair, or fur — grown using advanced HPHT technology and identical to a natural diamond.
Every step of the ashes-to-diamonds process is calm, transparent, and documented.

Begin With the Welcome Kit
We send a secure Welcome Kit so you can collect the ashes or hair gently and privately at home.
Only a small amount is needed — about half a cup of ashes or a lock of hair.
Many families choose to begin with the kit and decide later when the time feels right.
Sending a Small Amount of Ashes
Using the prepaid, insured shipping container included in your kit, you will send a small amount of ashes or hair to our laboratory.
Every shipment is handled discreetly and tracked to ensure safe arrival.
“We treat every package with the same care we would give our own family member. You will be notified the moment it arrives safely.”
How much is needed
Typically about half a cup of ashes (around 100g) or a lock of hair is enough to grow a memorial diamond. In many cases, this is sufficient even when families choose multiple diamonds.
What happens to the rest
Only the required amount is used. The remaining ashes stay with your family and can be returned according to your preference.
Shipping safety
The Welcome Kit includes guidance for discreet packaging and a tracked, insured shipping method so you always know where your ashes or hair are.
If you’re not ready
Many families request the kit simply to learn more. You can take your time — there is no pressure to send anything until you feel ready.
Treated Individually — Always
Ashes are never mixed with others
Only the required amount is used
Remaining ashes stay with your family
Ashes or hair are carefully tracked throughout the process
Individual handling
Each memorial diamond is created from ashes or hair handled individually from start to finish. At no stage are ashes combined with another family’s ashes or hair.
Chain of custody
We maintain careful documentation during each stage of the process so you always know where your ashes or hair are.
Pause option
If you need time before the growth phase begins, the process can be paused. You remain in control of the pace.
Updates
Families receive gentle progress updates — enough to reassure you without overwhelming you with technical details.
Preparing the Ashes With Care
Once your ashes or hair arrive, we begin the first scientific step of the cremation diamond process.
Carbon is isolated from the ashes or hair through a specialized purification procedure. This produces high-purity graphite powder, which becomes the foundation for growing your diamond.

If this feels right, you can begin gently with a Welcome Kit.

No obligation. Take your time.
Diamond Growth Using HPHT Technology
The purified carbon is placed into a High Pressure High Temperature (HPHT) growth chamber.
This technology recreates the natural environment where diamonds form beneath the Earth’s surface.
Over several months, carbon atoms slowly crystallize — forming a real diamond grown from your loved one’s carbon.
Each diamond is grown individually to preserve identity and quality.
Expert Cutting & Polishing
Once the diamond is fully formed, our master cutters carefully study the rough stone.
They determine the ideal proportions and cut the diamond to reveal its brilliance and clarity.
This stage transforms the raw diamond into the finished memorial diamond you will receive.
Certification & Personalization
Each diamond is certified by Saint Diamonds to confirm its authenticity and origin. Independent grading by IGI or GIA is also available for additional verification of quality.
Many families also choose to add a laser inscription on the diamond’s girdle — a name, a date, or a small message preserved forever within the stone.
What This Becomes
“A physical connection that you can hold, wear, and keep close, forever.”
How Long Does the Process Take?
Because we grow each diamond individually, the process typically takes 4 to 8 months. We prioritize quality and respect for the ashes over speed.

There is no rush. Many families begin simply by receiving the Welcome Kit and deciding later.
Several factors influence the timeline:
Diamond size
Larger diamonds require longer growth cycles.
Color goals
Some colors require additional calibration during the growth stage.
Growth stability
HPHT cycles are carefully monitored to ensure diamond stability and quality.
Certification
Independent grading by IGI or GIA may add additional processing time depending on laboratory schedules.
A gentle first step.
Begin When the Time Feels Right
There is no deadline. Whether it has been weeks, months, or many years, you can begin gently and decide everything else later.
Many families start simply by receiving the Welcome Kit.
