I was friends with two western reared Indians whose family in India had a fabulous giant green emerald that their ancestors wore as they rode on horseback from village to village that they owned to show their leadership.

They still have what they say is the original - I was at a giant family wedding (thousands of people) where the groom wore it. However I assume they sold off the real one years ago because the family is in decline. They've sold off all of their land except one area near Hyderabad and when I visited them last they were in the process of selling even that. It only took three generations to lose it all.
