The custom of wearing the wedding ring on the annular has different origins. The Egyptians believed that in this finger there was the so-called “vena amoris” a vein directly linked to the heart.
According to Christian culture, the annular is the finger that the priest touches, invoking the Father, the Son and the Holy Spirit. In Chinese tradition, every finger of the hand symbolizes a familiar figure in our lives. The thumb symbolizes the parents, the forefinger the brothers, the middle finger symbolizes ourselves, the annular our love, and finally, the little finger symbolizes our children.
In our culture, the wedding ring is the symbol of the union between lovers; it can be made by varied materials, such as gold and silver or have many shapes, but in the centuries, its meaning hasn’t changed: it represents loyalty and love.
The wedding ring is generally worn on the left hand, while in the countries of Central and Eastern Europe the wedding ring is worn on the right hand. Its weight generally ranges from 3 to 16 grams and there are several types.
The Barbarians were one of the first people to use the ring as a sign of fidelity during the marriage. In Roman times, however, we find the "vinculum", an iron ring worn at first only by men, which served to celebrate the promise of marriage. The rite of wearing the rings at the finger after the wedding was established after 1500. The practice of engraving the names and the date of the wedding in the ring goes back to the 17th century.
