Lab-grown diamond producer Ethereal Green Diamond debuted the world’s largest lab-grown diamond at the JCK Las Vegas Show earlier this month. The 50.25 ct. polished diamond usurps the 30.18 ct. Pride Of India diamond, also grown by Ethereal Diamond, as the biggest lab-grown diamond; that diamond took the mantle of “largest” just last year.
Before its debut in Las Vegas, the International Gemological Institute (IGI) announced that it’s analyzed and certified the gem. “This gemstone is a paradigm shifting breakthrough, surpassing 50 carats while exemplifying preeminent standards of sophistication and quality,” said Tehmasp Printer, president and managing director of IGI India, in a prepared statement. “We are delighted to witness and support the remarkable advancement and popularity of lab grown diamonds IGI fostered 18 years ago, by opening our doors to the world’s producers.”
Named “Shiphra” (the Hebrew word for “beautiful”), the 50.25 ct. lab-grown diamond is a Type IIa emerald cut measuring 22.95 x 18.45 x 11.57 millimeters, with G color, VS2 clarity, and Excellent cut, polish, and symmetry. The crystal from which it was polished was grown over a period of eight months using the chemical vapor deposition (CVD) method of growing.

“This magnificent diamond represents the culmination of our team’s relentless pursuit of excellence,” said Hirav Anil Virani, managing director of Ethereal Green. “By pushing the boundaries of what is possible, we aim to redefine the perception of lab-grown diamonds. Ethereal Green’s commitment to sustainable practices ensures that each diamond produced is not only visually stunning but also ethically sound.”
Ethereal Green announced that the diamond has already been sold to NYC-based lab grown diamond brand Shiphra Jewelry, the gemstone’s namesake. —Ruby Baybei
