Elaborate arch-shaped man's amulet case, ga'u, made of copper alloy. The cover has embossed decoration depicting the yidzhin norbu, the wish-fulfilling jewel. The case has two squared handles at each side and a loop for suspension at the top. Lining the base is a piece of paper in the shape of the box and painted with a robed figure.
Large g’au such as this example could have been worn whilst travelling. Travelling was a time when people were particularly vulnerable and often several g’au were carried to provide extra protection. When travelling this g’au would probably have been worn on a sash, slung from shoulder to waist. However it’s flat bottom also allows for it to be placed on a shelf as part of a shrine.
