Tarnished reputation?

Gold maintains its lustre without tarnishing in air or water and is one of the least reactive of chemical elements. It is insoluble in nitric acid which otherwise dissolves metallic elements, a particular property that has been used to confirm the presence of gold and gave rise to the term ‘acid test’. However, while gold does not tarnish, the same may not necessarily be said of the reputations of those that handle it. Dubai’s reputation is under attack and, in particular, that of Dubai-based gold refiner Kaloti Precious Metals, the largest gold refinery in the Middle East.
