When a person dies, cremation is an increasingly popular option. The practice eclipsed burials in the US in 2015 and is expected to make up more than half of all body disposals by 2020, according to the Cremation Association of North America.
But instead of storing a loved one’s cremains in an urn or sprinkling them outside, a growing number of bereaved consumers are doing something more adventurous: forging the ashes into diamonds.
This is possible because carbon is the second-most abundant atomic element in the human body, and diamonds are made of crystallized carbon. Researchers have also improved ways to grow diamonds in the lab in recent years.
While at least five companies offer a "memorial diamond" service, Algordanza in Switzerland is one of the industry leaders — its services are available in 33 countries, and the company told Business Insider it sold nearly 1,000 corporeal gems in 2016. Algordanza also claims to be the only company of its kind that operates its own diamond-growing lab for cremains — one of two in the world. (The other is in Russia.)
"It allows someone to keep their loved one with them forever," Christina Martoia, a spokesperson for Algordanza US, told Business Insider. "We’re bringing joy out of something that is, for a lot of people, a lot of pain."
Here’s how the company uses extreme heat and pressure to turn dead people — and sometimes animals — into sparkling gems of all sizes, cuts, and colors.

Making a diamond from a dead person begins with cremation. The process typically leaves behind about 5 to 10 pounds of ashes, much of which is carbon.
Styles of cremation differ from culture to culture. Some use hotter temperatures for longer, which allows more carbon to escape into the air as carbon dioxide (which may mean more ashes are needed to form a diamond).
Martoia said Algordanza requires a minimum of one pound of cremains. "That’s kind of the magic number, where our engineers can guarantee there will be enough carbon to make a memorial diamond," she said.
When the company receives ashes from a customer, a technician puts a sample into a special oven to see if there’s enough carbon to grow a diamond. If there’s not enough, the amount of carbon in a lock of hair can make up the difference.
