Human cultures are amazingly diverse and differ in a mind-boggling number of different ways. Yet, some customs such as marriage are shockingly universal. Consider the considerable geographic barriers, such as mountains, oceans and deserts that once separated mankind before advanced forms of transportation. However, marriage has somehow managed to permeate its way onto nearly every continent and culture. Likewise, some of the customs of marriage, such as the wedding ring, have also enjoyed a similar popularity.

Amazingly, weddings and wedding rings have made their way into every major culture and geographic region across the globe. Generally, wedding rings are worn on the left land and on the fourth finger. The exact reason for this is unclear, but it seems safe to conclude that this is due, at least in some part, to the fact that roughly three-quarters of people are right handed. Many people like to have their dominant hand free of any encumbrances. The custom of wearing one’s wedding ring on the left hand may find its origin in this fact.

Another common practice concerning wedding rings is to have the rings inscribed. Inscriptions can vary wildly, but will usually somehow reference undying love, eternal love or some other similar sentiment. Of course, this does make for some bittersweet awkwardness if the marriage ever ends in divorce. “I will love forever,” tends to be a bit awkward once a marriage has ended.

Metals have been used extensively in wedding rings due largely to the most obvious points, namely metal’s durability and beauty. It is only in recent times that metalworking has become more widespread and common. This, of course, means that in ancient times a metal ring, especially a beautiful one, would have been a rare and valued possession.

The association between weddings and wedding rings across cultures is truly remarkable. It is also impressive to consider that the circle has been so consistently used, instead of another shape such as a necklace or a pin on one’s clothing. No doubt this is partially due to the inherent geometric appeal of the circle. Considering that the circle has no beginning and no end, it is perfect for use as a symbol for something that is eternal, such as love.
