Bronze to the lost wax. Inspired by the archaeological remains of Ribe, Danmark. This type of Viking brooch is part of the accessories used during the first century by many of the Nordic women, specifically those who lived in what is now Denmark. It was used to close mainly the thick woolen fabrics as a layer that they used to protect themselves from the cold. I have been found with similar strokes, in multiple variants in the different Viking sites of the country, dating from 600 to 900 AD. His name is honor to Harald Blåtand, son of Gorm and Thyra, last kings of the Danish Viking dynasty. Harald has gone down in history as the King who united the Vikings with the Christian faith. He was nicknamed Blåtand (dark-skinned man) The English interpreted his name as Bluetooth (blue tooth), in his honor the name was given to the wireless communication technology "Bluetooth" whose sign is the union of the two letters of his name H and B in the runic alphabet.
