Technical Procedures

From Ashes to Cremation Diamonds: LONITÉ's Laboratory and Process

Cremation Diamonds Technology

A diamond is in fact crystallized carbon. Carbon (C) accounts for 18% of any animals’ bodies, which makes turning ashes into cremation diamonds possible.

Natural diamonds grow in an environment of extreme pressure and high temperature deep in the earth's mantle over millions of years.

At LONITÉ, we recreate these high-pressure and high-temperatures natural environments in our laboratory over a period of 9 to 12 months (1 ct).

To turn ashes or hair into diamonds, below ashes amounts are required.

Time - From Start to Finish

It takes an average of 10 months to turn ashes into a one-carat diamond. The actual time of each diamond is dependent upon the size ordered (normally 5-18 months).

Optional GIA or IGI certification, jewelry setting, and laser inscription services are offered at extra cost where it takes an extra 1 or 2 months for each service chosen.

Cremation Diamond Colors

The "Naturally Amber" color in our cremation diamonds comes from the presence of Nitrogen.

The presence of Boron in the ashes will turn the diamond into a blue color.

If our lab removes both nitrogen and boron from the ashes, cremation diamonds will become colorless.
