How ashes become a diamond
A remarkable process
Heat, pressure, time, and carbon. That's what's needed for a diamond to form in the earth's mantle. Our machines simulate these same conditions and grow a real diamond from the carbon in your loved one's ashes.
An intricate 7-stage journey
Order & secure shipment
You begin online: choose your diamond, material, and setting, then complete checkout. We follow up by email with pickup or shipping instructions for ashes or hair. The optional Welcome Kit page explains secure packaging if you want that path—most families proceed from the order confirmation email.

Carbon purification
We isolate carbon from the other elements in ashes or hair. Much elemental carbon burns off during cremation, but carbonates in bone remain—that is the carbon we extract. Roughly 0.5–4% of remains are carbon; purification takes many weeks. The result is graphite powder—the starter material for the diamond.
Want third-party testing of total carbon content in ashes or hair? We offer it free of charge.
Diamond growth
Diamond growth takes place in our Zhengzhou, Henan laboratory network, staffed by experienced materials scientists and technicians. Our machines replicate the extreme temperature and pressure found deep within the Earth. Over time, your loved one's carbon crystallizes on a diamond seed and grows into a rough memorial diamond.
“When you commission a RisenGem diamond, it is completely custom-made and as unique as your loved one.”
— Co-founder Adelle Archer
Diamond quality assessment
After the rough diamond forms, we scan it (like an X-ray) to map inclusions and confirm the planned shape and size will fit cleanly in the rough without visible flaws. Quality over speed—we want your loved one's diamond to be right.
Diamond cutting
Once your diamond passes inspection, a master cutter shapes it with care. Our cutters bring decades of experience. Cut has the biggest influence on brilliance—we are selective about who we work with.
The finishing touches
Diamond coloration*
If you chose a red, green, or black diamond, we run an additional coloration stage. High-energy particles combine with natural elements (such as nitrogen and boron) to create color centers through the stone. Black diamonds can take about three months to become fully opaque.
Grading & engraving
Your loved one's diamond is a real diamond, so we have it certified by independent gemologists. We work with IGI USA, a respected grading lab. They examine color, clarity, and cut—and can laser-engrave your personal inscription microscopically.
Jewelry setting*
We can help arrange a setting, or you can set locally. Choose from our curated line or work with a jeweler on a custom design. Setting planning starts after cutting so dimensions are final.
