110kt Cora Sun-Drop is the world’s largest yellow pear-shape diamond

The National History Museum in the UK has added to its rich treasures, the 110-carat Cora Sun-Drop, claimed to be the world’s largest known vivid yellow pear-shape diamond. It was mined in Africa and lent to the museum by Cora International, the company that crafted the original rough diamond. The diamond gained its colour from the minimal amount of nitrogen in its carbon structure making it extremely rare in nature. The museum’s Vault gallery will display the Sun-Drop for six months. The Vault is ‘a permanent gallery dedicated to some of nature’s most rare, unique and valuable treasures’.
