They are sold everywhere. Arabs and Indians like gold. The price of gold is cheaper than that in China because its purity is not as good as that in China. The biggest gold jewelry market I have ever seen in Abu Dhabi is the gold center next to Madinat Zayed Shopping Center. Just take a taxi and tell the driver that it should be on the new airport road. I even saw a gold ATM in Marina Mall. You can buy gold ornaments by swiping your card directly on the machine.
