Relics dating to 6,000 years ago, adding papyrus scrolls, are facts of the exchange of braided rings of hemp or reeds among spouses. Ancient Egypt considered the circle to be an emblem of eternity, and the ring served to symbolize the perpetual love of the spouses. This was also the origin of the custom of wearing the wedding ring on the ring finger of the left hand, as the historical Egyptians believed that this finger enclosed a special vein that was attached without delay to the heart, denominated in Latin the “Vena amoris”. The Western traditions of marriage ceremony rings can be traced to historic Rome and Greece, and were first linked to the marital dowry and later with a promise of fidelity. The modern exchange of rings derived from the customs of Europe in the Middle Ages as a part of Christendom.  In the United States, marriage ceremony rings were at first only worn by wives, but became common for both husbands and wives during the 20th century. For example, see the picture below of the Byzantine ring depicting Christ uniting bride and groom. Also, in the Middle East the puzzle ring was a ancient custom: this ring consisted of a couple of pieces that joined in combination into a cohesive band when worn correctly. The object of this variety of ring was to render it very challenging to put on the finger correctly such that, if the wife removed it, her husband would know. The fede ring, being a band inclusive of two hands clasped in betrothal, is another old custom of Europe that ostensibly dates from antiquity. Limited gold content material in the United KingdomIn 1942 during the Second World War, British wartime regulations on the manufacture of jewelry resulted in “utility” wedding rings that were limited to a maximum mass of two pennyweights, being a bit of heavier than 3 grams, and were forged of 9 carat gold in preference to the traditional 22 carat.  The Regional Assayer Office hallmarked these rings, which guaranteed their gold content and compliance with the wartime regulations with a unique utility mark adjoining to the mark for the year on the inside of the band; the hallmark resembled a capital “U” with the base curve absent or two parentheses enclosing a space, i. This could be a new ring for the bride or both, or reusing the engagement rings. Any engagement rings can then remain on the left hand or be transferred to the proper hand. In Germany, in has been well-known for both the bride and the groom to wear a marriage ring since at the least the 1870s and mentions of couples exchange rings during the bridal ceremony in the Netherlands are available as a minimum as far back as 1815.  In Brazil, Mexico, the Netherlands, and Spain both sexes also wear engagement rings, and the groom’s ring often turns into a marriage ring in the nuptial trade ceremony. Compositions and stylesIn Western nations, wedding rings are often forged of rose, white, or yellow gold; palladium, platinum, argentium silver, or, more lately, silicone.  The perpetuity of noble metals symbolizes the permanence of the wedding.
