Which state produced the Green Diamond, which Prime Minister Modi gave to the First Lady and US President Joe Biden?.

Prime Minister Narendra Modi gave US President Joe Biden and First Lady Jill Biden a special gift. It was created by a Surat, Gujarat-based laboratory. Similar chemical and optical properties can be found in the lab-grown 7.5-carat green diamond as they do in diamonds that are extracted from the Earth naturally. Since resources like solar and wind power were used in its production, the diamond is environmentally friendly. It is accredited by the Gemological Lab, International Gemological Institute, and emits just 0.028 grams of carbon per carat.
