The Viking Norse Calvarium Ring was a popular and widely used accessory in ancient Scandinavia. It is believed to have been worn as a protection against malicious spirits, as well as warding off sickness and bad luck. These rings were believed to have magical qualities, such as giving their wearer strength and good fortune. They were made of silver or bronze and often had intricate designs that symbolized various gods or goddesses. In some cases, the ring might even be inscribed with runes in order to strengthen the intended effect of the jewelry’s protective powers. The use of these rings was widespread across many Viking communities, and they remain attractive pieces today as memorials to this lost culture.
