Ex-US First Lady Jill Biden wrote about the 7.5-carat lab-grown diamond PM Narendra Modi had gifted her. Calling it big and gorgeous in her book, Jill said, "It belonged to the federal government." She said that PM Modi told her the diamond's value was $2,500 (₹2.37 lakh) but US State Department appraised it at $20,000 (nearly ₹19 lakh).
