Dubai’s internationally famous Gold Souk has its roots in the 1940s, when Indian and Iranian traders began setting up stalls in the area. Today, it’s one of the world’s busiest jewelry markets, with hundreds of shops and stalls selling just about everything that glitters—namely, gold. An estimated 20 percent of the world’s gold passes through the souk, with a whopping 10 tons (9,072 kilograms) for sale in the market at any given moment.
