The Carmen LĆŗcia Ruby. The 23.1-carat Burmese ruby, set in a platinum ring with diamonds was donated to the Smithsonian by businessman and philanthropist Peter Buck in memory of his wife Carmen LĆŗcia. The stone was mined from the famous Mogok region of Burma in the 1930s. While sapphire, emerald and diamond gems weighing hundreds of carats exist, high quality Burmese rubies larger than 20 carats are incredibly rare.
