The world's first diamond made from peony-derived carbon elements made its debut on Wednesday in Luoyang, Henan province.

The 3-carat diamond was sourced from red peonies from the national flower garden in Luoyang. It was donated to the Luoyang National Peony Garden by Luoyang Time Promise Co.

"The diamond is valued at 300,000 yuan. It is cultivated from peonies using our biogenic carbon extraction technology, subjected to high temperature and pressure, and then cultivated," said Wang Jing, head of the company.

At the end of March, the peony garden cooperated with the company and used a nearly 50-year-old peony in the garden to carry out the diamond cultivation.

Bones and hair contain carbon elements, of which diamonds are composed. So, the technology adopted extracts carbon elements in a specially designed device and breaks the chemical bonds between the extracted carbon atoms. Then, those elements recombine into a diamond structure before forming a diamond, according to the company.
