The price of gold is higher than it has been in 17 years - pushing $500 an ounce. But much of the gold left to be mined is microscopic and is being wrung from the earth at enormous environmental cost, often in some of the poorest corners of the world.
And unlike past gold manias, from the time of the pharoahs to the forty-niners, this one has little to do with girding empires, economies or currencies. It is almost all about the soaring demand for jewelry, which consumes 80 percent or more of the gold mined today.
The extravagance of the moment is provoking a storm among environmental groups and communities near the mines, and forcing even some at Tiffany & Company and the world's largest mining companies to confront uncomfortable questions about the real costs of mining gold.
Not just diamonds.
