Rare ‘diamond within a diamond’ is unearthed in India and is named the ‘Beating Heart’

A unique ‘diamond within a diamond’ has been unearthed, according to a company in India’s Surat – one of the rarest in history when it comes to such stones. 

V D Global named the 0.329-carat piece ‘Beating Heart’ and said it consists of a piece of diamond with a smaller freely-moving piece trapped inside, according to the Times of India. 

The stone was originally found in the rough in October last year by the diamond manufacturer that operates from Surat and Mumbai, according to the Independent. 

The Gem & Jewellery Export Promotion Council (GJEPC) set up by the Indian government said the ‘Beating Heart’ joins a little group of similar natural diamonds such as the Matryoshka diamond from Siberia, which was first recorded in 2019.

The authenticity of the stone was confirmed via further analysis, using optical and electron microscopes.

‘I have certainly never seen anything like the ‘Beating Heart’ during my last 30 years in the diamond sector,’ Samantha Sibley, Technical Educator at De Beers Group Ignite said.

‘Using the expertise of De Beers Group, we can shed light onto the formation and structure of this natural specimen and share these insights with a wider community of diamond professionals,’ Ms Sibley reportedly added. 

The rare diamond has ‘etch features’ visible on both the smaller diamond in the inner cavity, it was found. 

Experts explained the cavity may have formed due to the preferential etching of an intermediate layer of poor-quality fibrous diamond.

In 2019 another unique ‘gem inside a gem’ diamond was unearthed in Siberia.

The 800 million-year-old two-in-one jewel was said to be priceless and the only such discovery in the world.

The so-called ‘Matryoshka’ diamond resembles traditional Russian nesting dolls, one inside the other.

Inside, the tiny nested diamond in its own sealed air space has an estimated weight of .02 carats and dimensions of 1.9×2.1×0.6 mm. The smaller diamond rattles inside the larger jewel.
