Nowadays we are used to seeing rings on almost all the fingers of the hand, even several on each one, but until relatively recently, wearing a ring on one finger or another traditionally had a different meaning:
In the left hand it reflects creativity, but in the right hand it means that the person is very perfectionist.
If worn on the left hand it indicates a decisive and strong character. On the right, quite the opposite, an insecure character.
People who wear it on the left are strong, communicative and with the soul of a leader. Wearing it on the right pinky reflects patience.
Great self-esteem for those who wear it on the left hand and a dominant character on the right.
The meaning is the same in both hands. They are very sentimental people.
