The silver and gold that was used to make King Philip II’s diadem would have originally been mined, processed, and then shipped to a jeweler or expert artisan.
The adhesion of gold with the use of heat helps promote interdiffusion with the underlying metals which usually consist of silver or copper.
[3] While examining the diadem the most notable feature is the Herakles knot located on the front imitating a cloth headband.
On each side of the Herakles knot the metal makes a weave like pattern, continuing the cloth headband imagery.
While the current diameter is 25 cm, the diadem was made to be adjustable with the two ends that fit into a smaller section in the back.
