ANCIENT MINOAN SIGNET RING
While Minoan women were always held in high regard, they did not rule the roost. They are depicted in positions of great honor and would appear alongside men. Examples of this are found in carved signet rings. Signet rings served as stamps of ownership and identity - and, according to Bettany Hughes, even speculated as the Bronze Age equivalent of a credit card! Thus, making it the first PowerJewel.
This gold signet ring is from an excavation of the Mycenaean cemetery at Aidonia in Greece, dated 1500 - 1200 BC.
