The custom of wearing the wedding ring on the left ring finger dates back to the time of the ancient Egyptians , who believed that there was a vein, in which feelings ran which, starting from the left ring finger, went straight to the heart.
Binding the ring finger therefore meant guaranteeing the fidelity of the beloved.
The ancient romans they exchanged iron rings.
According to Jewish law, the exchange of rings alone was enough to make marriage legal.
In the Middle Ages the faith was of great workmanship and preciousness and often the groom ringed the bride with three rings.
