The International Gemological Institute (IGI) has analyzed and graded the world’s largest lab-grown diamond to date: a 75.33-carat square-emerald cut stone named the Celebration of India.

The diamond was created by Ethereal Green Diamond LLP in collaboration with RockRush. It was displayed to the industry at the JCK Show in Las Vegas from May 31 to June 3.

IGI graded the Celebration of India as a type IIa diamond with excellent polish and symmetry.

The stone took approximately 270 days to grow to 190 carats in its rough form. The Ethereal Green team then spent another 30 days cutting and polishing the gem.

Ethereal Green director Hirav Virani stated, “At Ethereal Green, we are constantly innovating, adopting new technology, and creating benchmarks. It gives me immense pleasure to showcase Celebration of India, which has not only created a new milestone of 75 carats but also commemorates sovereign India’s remarkable achievements over 75 years of independence.”

The lab-grown diamond creator also showcased a unique 30.69-carat ring-shaped diamond, crafted via Chemical Vapour Deposition (CVD) from a single crystal-grown rough stone.

IGI identified the Infinity Ring as a type IIa diamond with excellent polish and symmetry.

“The Infinity Ring is a testament to our skilled workmanship. This unique ring was carved from a 98.88-carat rough CVD stone,” added Virani.

According to the manufacturer, the Infinity Ring took around 146 days to grow. Its transformation to its final ‘freeform modified shape’ took 90 days of meticulous crafting at Ethereal Green’s state-of-the-art facility in Gujarat (Surat), India.

CEO of IGI, Tehmasp Printer, commented, “These achievements are striking examples of Ethereal Green’s dedication to innovation and ingenuity in consistently breaking their own records. We congratulate their team on developing these extraordinary creations, which showcase limitless possibilities with advanced technology in the lab-grown diamond sector.”

Both the Celebration of India and the Infinity Ring will now be displayed at the RockRush store in SoHo, New York.
