This is the story of precious gems, from emeralds and rubies, to sapphires and pearls. Explore their history and geology, as well as their famous owners, from Elizabeth 1 to Elizabeth Taylor, Marie Antoinette to Marilyn Monroe, Coco Chanel to Beyonce. Selecting ten of nature's most dazzling jewels, Helen Molesworth makes journeys across the world to trace stones from their discovery to the moment a glimmering cut and polished masterpiece is traded, and then fought over, adorns oligarchs and kings, falls out of favour, and then raises eye-watering sums in another age.
