These are 14K yellow Gold, vintage handmade Olive branch earrings.
The olive branch is usually a symbol of peace, harmony and hope.
The dove and olive branch is used as a symbol of peace, further to the Christian belief of the story of Noah and the Flood (with a passage that describes a dove returning to the ark with an olive leaf, a sign of life after the floods).
It is also a symbol of victory. It seems that the origin of this meaning comes from Greek mythology: the story of when Athena competed with Poseidon for possession of Athens. While Poseidon claimed possession of the city by thrusting his trident into the Acropolis, Athena took possession by planting the first olive tree beside the well. The court of gods and goddesses ruled that Athena had the better right to the land because of her gift. Olive wreaths were also worn by Olympic winners.
