The company V D Global has named the rough diamond weighing 0.329 carats “Beating Heart” and reported that it contains another diamond moving freely inside, as reported by Independent on April 16. This gemstone was discovered last October by a diamond mining manufacturer in Surat and Mumbai.
The Gem and Jewellery Export Promotion Council (GJEPC), established by the Egyptian government, stated that “Beating Heart” belongs to a rare group of naturally occurring double-structured diamonds like the Matryoshka found in Siberia. The authenticity of the stone was confirmed through further analysis using optical and electronic microscopy.
“I have never seen anything like ‘Beating Heart’ in my 30 years in the diamond industry,” shared Samantha Sibley, a technical training specialist at De Beers. “With our working experience, we can clarify the formation process and structure of this natural specimen.”
Beating Heart features deep engravings that are clearly visible on both the outer diamond and the hollow cavity inside. Experts explain that the cavity may have formed due to the erosion of the intermediate layer. According to Jamie Clark, the director at De Beers Institute of Diamonds, Beating Heart is a special example demonstrating that the natural diamond formation process is an intriguing area of research.
In 2019, a diamond encased within another diamond was discovered in Siberia. This 800-million-year-old gemstone is an invaluable find and was named Matryoshka after the hollow Russian doll. The inner diamond is estimated to weigh 0.2 carats and measures 1.9×2.1×0.6 mm.
