De Beers has just announced a rare diamond discovery — a small naturally occurring diamond crystal that moves freely inside a cavity of a rough 0.329ct diamond. De Beers has named the rare diamond Beating Heart.
Using optical and scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), fluorescence and phosphorescent imaging, the researchers conducted in-depth analysis of the diamond. They concluded that the formation of the diamond cavity is caused by the dissolution of the growth layer of the loose diamond structure, while the remaining smaller diamonds are relatively dense and thus preserved.
The origin of the rough stone was not confirmed, but is presumed to have come from one of De Beers’s mines in Africa or Canada. Given its small size, the stone will not be cut or polished by De Beers and will be an important future study of the diamond formation process.
Etching features are seen on the lumen of both the rough diamond and smaller diamonds, as shown in scanning electron microscope (SEM) images
