“Gems have been coveted for thousands of years—hoarded by rulers, looted by opportunists, used as bargaining chips by the desperate, and deployed in portraiture to signify wealth and status. Individual gems, inherited through generations, have dense and illustrious histories of passing between allies and foes that sometimes add to their value and allure. But many of the world’s most famous jewels hide a controversial or mysterious past behind their glittering façades.” – Mental Floss
