Because the more valuable this diamond becomes, the more we will be able to fund life-saving research against breast cancer.

How was The World’s Most Precious Stone made?

Hair and diamonds are made out of carbon. In nature carbon is compressed and heated during millions of years at the center of the earth to make a diamond. Lifegem ® recreated those natural conditions in a lab and turned a single lock of Danielle’s hair into a perfect 1.59 Carat diamond.
