A very rare natural diamond has been unearthed in India and given the name Beating Heart for its breathtaking “diamond within a diamond” formation.
After being recovered in the rough and named by diamond manufacturer VD Global in Surat, India, the gemstone was analyzed by De Beers Institute of Diamonds at its facilities in Maidenhead, England, in November 2022. Experts classified the 0.329-carat gem as being a type IaAB diamond of D-color, with an internal cavity encasing a smaller diamond, ostensibly trapped, but free to move within the cavity.
