Found inside a mine in Botswana last April, the second-largest rough diamond ever documented—at a whopping 1,758 carats—recently sold to Louis Vuitton. While the brand is best known for their leather goods and apparel, the purchase of the Sewelô (as the stone is called) is evidence of their commitment to the high-end jewelry market.
