The Cora Sun-Drop Diamond, at 110 carats the largest vivid yellow pear-shaped diamond in the world, has gone on display in The Vault at the Natural History Museum in London. It has been lent to the museum for up to six months by US firm Cora International. Click the title link for a jerky (on my PC) video of model Jerry Hall flashing the gem to news cameramen. Eat your heart out, ladies. How many of you looked that good aged 25, let alone 55? And note she is 6 feet tall, the perfect height for a model.
