How was gleninsheen gorget made?

A piece of gold was beaten flat and shaped into a crescent. The dots and rope molding design were created by a technique called repousse which means the design was incised into the back of the object so it would appear raised on the front. The circles were also beaten from gold sheet and decorated using a combination of incision and repousse. I do not know however how the circles were attached to the crescent but soldering was used in Ireland at this time so I'd say it was soldered.
